Title: CB550 refurb
Post by: Johnny4428 on August 27, 2024, 09:40:59 AM: Well after a nice run out on this machine on Sunday (although it drizzled the entire afternoon) I came back and parked bike on the bike lift and have decided to start a bit of resto work. I donâ€™t know how far this one is going to go in cash pit terms. I think it is mostly a cosmetic project as the engine runs great without any clattering or rattling. There s the usual head oil leak that I will sort so hopefully just a top end rebuild. Not decided whether I will remove engine from frame or sort with engine in place. I have done quite a bit to this bike already to put back on the road such as swingarm bushes, brakes, new handlebars clutch basket rubbers. Looking forward to all the fun ahead! Winter project? Maybe more than one winter, Iâ€™ll see how thing go on the expenditure.😜

Post by: taysidedragon on August 27, 2024, 11:28:35 AM: These projects grow arms and legs as you go on. It doesn't look in bad condition as it is.
Apart from cleaning and polishing, what do you think needs doing?
Title: Re: CB550 refurb
Post by: SteveW on August 27, 2024, 01:27:21 PM: I got my 550 out of the garage last October, just for a wash and polish.
By the end of the day the engine was out, it just sort of happened :o

Slowly going back together now.

Post by: Laverda Dave on August 27, 2024, 02:20:40 PM: It will go one of two ways Johnny and usually the more expensive one once you dig into it! It is surprising though what a strip down of wheels and guards off etc followed by a good clean getting into the nooks and crannies with a final polish can achieve with no big expenditure, just hours of time. My VFR came up like new with the same treatment 8).

If I can offer one piece of advice though following a very painful experience last week......use ratchet straps on the bike whilst it is on the lifting bench to secure it. I put my Triton on the lifting bench last week (it only has a side stand) and went to tie it down but the straps were under the lifting table. I jacked the table up about 300mm to get my hand under to reach the neatly rolled up straps and whilst I was down there the bike rolled off its side stand and went crashing to the floor hitting the nearly completed Ratty on the way down. Damage to the Triton was two badly dented mudguards, Bent number plate and taillight, bent clip-on, bent headlight bracket, twisted headlamp and indicator with a pint of oil leaking all over the floor for good measure. I was very lucky to have removed the alloy fuel tank and seat before I wheeled it onto the bench otherwise the tank definitely would have been toast. Damage to Ratty was a gouged generator cover and badge. If I had reached to get the straps from the other side it would have fallen on me (a softer landing ::))! A very expensive lesson learned, I should have taken the bike back off the stand to reach the straps.

Post by: Johnny4428 on August 27, 2024, 04:04:23 PM: Holy shit Dave! Was going to say at least nobody hurt! Very easy overlooked, thanks for advice â€œbelt and bracesâ€of course. I have started with the wheels for some reason, new bearings and seals, new rims and spokes and new tyres of course. Iâ€™m not going to fix what ainâ€™t broke as far as engine goes. Ash has kindly got hold of paint for me which will be picked up in October by Ian, and that will be a job for next spring. Iâ€™ll see how it goes, some bits and pieces to re chrome otherwise maintain patina. Yes I probably will overspend on it I have with every resto I have done so far! Going to juggle garage work with a bit of house decorating too just to keep the peace.😂

Title: Re: CB550 refurb
Post by: McCabe-Thiele (Ted) on August 27, 2024, 05:05:28 PM: Bryan is right lol - I estimated what mine would cost to rebuild based on my 400. I was close enough - about Â£700 over in the end as there were some unexpected costs. It's probably worth half of what I'm into. My last major project I've told she who must be obeyed.

Are you planning on rebuilding the wheels yourself Johnny? My 550 needs new rims and spokes but as I have never worked on a wheel before Iâ€™m thinking that for my build this is a job I wonâ€™t do but I would be very interested to read about any work you do on the wheel rebuilds.

Title: Re: CB550 refurb
Post by: Johnny4428 on August 28, 2024, 07:52:08 AM: Yes Mike I will do the wheels myself, very satisfying job. As Ted says some good videos on YouTube. If itâ€™s something you think you could have a go at itâ€™s a very handy skill to have. I thought if I can do it anybody can. Many years ago I read a bicycle maintenance book which contained a section on wheel truing. After mucking about with bicycle wheels i managed reasonable results in straightening and truing up.

Title: Re: CB550 refurb
Post by: McCabe-Thiele (Ted) on August 29, 2024, 09:02:20 AM: Doing your own wheel building must be very rewarding that's a given. I've read with admiration here those members who have done it including overcoming issues like having been sent the wrong spokes etc. I am quite risk averse plus a serial overthinker especially in old age.
As I wanted my Hubs powder coating, anodised rims and to avoid any issues with the SS spokes I realised that as I was sourcing everything from CWC the actual labour charge for building the rims is a relatively small component.

I did not want to risk damage when fitting the tapes and tyres so had CWC do the lot. Twenty years ago I would have done them myself that's for sure. I look forwards to reading your build progress.
I believe one of the reasons we tinker with these old Honda's is the problems we face in learning to overcome obstacles picking up new skills in the process. That said we each have individual red lines.

Recently at the ripe young age of 76 earth years I leant how to fit a Helicoil for the first time as a carb bowl thread had stripped. My second Helicoil was visibly better than my first - so much so that I ended up removing the first attempt making it as good as the second one.
Title: Re: CB550 refurb
Post by: Johnny4428 on August 31, 2024, 11:58:10 AM: Never really thought about the original finish on these hubs before but looks like the outer flanges were lacquered but not the centres?
Title: Re: CB550 refurb
Post by: Sesman on August 31, 2024, 02:12:00 PM: Iâ€™m firmly of the belief that the hubs were satin polished and lacquered. Other opinions may differ.
Title: Re: CB550 refurb
Post by: Laverdaroo on August 31, 2024, 02:15:10 PM: Go look at Allan Millardâ€™s wheel building video on his you tube, itâ€™s on his Z900 build. Rather than lacing them vertically he does them flat in the vice on the bikes rear spindle. I copied him and found it much easier and you donâ€™t need any special kit etcâ€¦â€¦. Worth a look, helped me immensely and Iâ€™ve done 4 sets now. I had em checked at a vintage bike shop in Chard and he said he couldnâ€™t have done them any better so well chuffed!

Worth a look Johnny

Post by: Johnny4428 on August 31, 2024, 05:00:51 PM: Interesting Roo to see how the great Millyard does his wheels. Iâ€™m actually quite happy with the building process but can definitely take a tip or two there. Previous wheels I have done I have just buffed the hubs with a scotchbrite mop to leave a nice satin shine but just wondered if thereâ€™s anything to be gained by applying lacquer?
Title: Re: CB550 refurb
Post by: Laverdaroo on August 31, 2024, 09:53:53 PM: Only the fact that if it chips or comes away, youâ€™ll have to do some cunning masking to redo it if the wheels built. I part polished mine, that Kanuba wax is easier to apply than lacquer was my thought train when doing that job.

Post by: K2-K6 on October 07, 2024, 06:57:31 PM: I agree with Ian, unlikely in this material.

Looks to have been scraped by another object, then still used which has flattened any burr.

They are really, really tough material spec .... at the end of the world there'll be just cockroach and these old 70s Honda disc :D

There's no tracking at either end of that mark either, not inboard into mount flange or outboard in evidence of how a crack would ordinarily propagate.

Post by: Johnny4428 on October 07, 2024, 09:22:34 PM: I agree that I donâ€™t now think it is a crack. If it was manifesting itself from the outer edge of the disc it would be plausible.

Post by: Johnny4428 on October 10, 2024, 12:13:07 PM: No excess spoke Ted! If they are the correct spokes for the rim they and hub they should be sound. The tape will undoubtedly cushion the seat for the inner tube, I suppose there could be small burs on the nipple ends if it had been built using a screw driver. I just use fingers and spoke spanner.

It's really not that hard Mike once you've watched a few videos, the critical bit is getting CWC to send you the correct spokes, they've got mine wrong twice out of two builds. Quite enjoyable really.

Title: Re: CB550 refurb
Post by: McCabe-Thiele (Ted) on October 13, 2024, 07:54:06 AM: I don't know what mileage your bike has covered. As the engine is out have you checked the Primary Drive chain for wear, you can get an idea as to it's condition thought the sump hole.

I have to be honest I do not like the idea of a split link on a camchain, presumably you will have to take the barrel off to replace the base gaskets & liner O rings to avoid any chance of an oil leak.

FWIW as you have spoked your own wheels splitting the crank case is pretty straight forwards - its costs that mount of course as you go further into the engine.
Title: Re: CB550 refurb
Post by: Johnny4428 on October 13, 2024, 12:04:48 PM: Yes I havenâ€™t checked the primary drive chain yet Ted! I was just assuming by the way the engine ran that the lower end of the engine was not needing a lot of maintenance. The clock was reading in the region of 32,000 miles. Iâ€™m not daunted by having to split the cases but just thought I was not going down that route if I didnâ€™t have to. So the primary drive chain wear might dictate the next move.

Post by: Bryanj on October 13, 2024, 05:37:08 PM: At about Â£50 for the kawasaki one its one of those while you are there jobs(unlike theÂ£110 Honda one!) The expensive bits are the rubber dampers in the primary drive as there are 8 of them

Title: Re: CB550 refurb
Post by: Seabeowner on October 13, 2024, 06:41:13 PM: The Kawasaki primary chain is 92057-1011. I've fitted a couple. One has been in for about 5000 miles over the last 9 years. It was Â£39 then. But the 8 rubber dampers are another Â£35-Â£40. Plus the cam chain and the new seals and gaskets to it does mount up. I'd never split the bottom end of an engine until then and it was pretty strait forward with no special tools. A puller is needed to remove the primary shaft, but a long bolt with the correct thread was all that was needed.

Post by: Bryanj on October 13, 2024, 10:54:14 PM: You do need to pull the alternator rotor if you want to swap the crank seal
Title: Re: CB550 refurb
Post by: Sesman on October 14, 2024, 07:41:46 AM: You do indeed, and Iâ€™d recommend renewing the seals. What I was very poorly alluding to was if you donâ€™t have the special tool, leave the rotor on, split the cases then ease the rotor off with aid of a rubber hammer, applying judicious blows. Not ideal, but it works for me. You do need to be careful though as over enthusiastic blows will create problems. If in doubt Iâ€™d recommend buying or borrowing the rotor extractor tool.
Title: Re: CB550 refurb
Post by: Johnny4428 on October 14, 2024, 07:49:21 AM: I have a universal puller might be able to do something with that, I also remember something about a car wheel stud being of size, maybe it was a commercial one? Important to protect crankshaft thread though.

Looking at your alternator rotor what are those symetrical marks on the steel has something been binding or is it how they are machined when new? I think mine had a similar appearance.

Yes pleased with the wheels, although the spokes that were in the wheels were in remarkable condition although dull in colour. I have kept them with a view to replating them. But 30 odd quid for a replacement set from DS is it worth it?

I am a little behind you in doing the same thing with my engine I managed to strip the top half down and separated the head and bores, Then lower part of the upper engine casing, Can I just confirm the thread size is 16mm diameter x 1.5 thread that is required to remove the rotor? Unfortunate y compressor is not got enough power to undo the nut so will have to source anther way to crack the bolt off.

I look fwd to reading your progress I am a bit worried that this looks ever so complicated once you lift the upper engine casing off there's loads of moving parts that need carful stripping down and cleaning.

Can anyone suggest a good economical way for cleaning these parts I though of a cut open plastic drum and some petrol and just wash them in that .

As to rotor bolt use decent socket with tee bar and whack/shock with hammer of decent size

It's always difficult when replacing an old dog eared part with a new one and not to continue to replace other parts whilst you are there and winter is coming anyway etc, etc.......
Title: Re: CB550 refurb
Post by: McCabe-Thiele (Ted) on October 20, 2024, 11:06:01 AM: Not that it needs confirming, Bryan is correct, once you have the head & block off it's easy to work with the engine upside down,
I just made a sort of small wooden tressle to hold the casing. I use an old bakers oven tray underneath to hold any bolts or liquid spilling everywhere - large cat or dog tray works as well.

This photo is my high tech arrangement, I had some small extra bits of wood to use if needed as wedges. The casing did not sit on the head studs they were just clear of the base by about 1/3". The second photo was taken before I put some wooden packing in place.

Youâ€™re right Dave! I have gone from a top end strip to a complete strip. But nice to get a right look inside. The good news is I havenâ€™t found anything that desperately needs replacing apart from chains and primary rubbers.

Post by: Johnny4428 on October 23, 2024, 07:04:40 PM: After a bit of thought about the cost of plating, I had to remind myself that I was wanting to retain a bit of patina on this 50y old bike right from the get go. There is always a temptation to try and disguise every blemish or age related mark. After another look at everything I have decided to try and source some reasonable looking bits and pieces and keep the plating as a last resort. I have cleaned up the rear indicators and am quite happy with them but the front ones have suffered quite a bit of the old metallic acne! So anybody by chance have a couple of these indicator shells? I have seen a few on flea bay but Iâ€™d try here first.

Title: Re: CB550 refurb
Post by: McCabe-Thiele (Ted) on October 31, 2024, 11:59:27 AM: In the winter months when painting small items (e.g.brackets) I put the item in my spray booth (a cardboard box) raising item off the ground on a block of wood. I then use a two speed 1.5 kw fan heater to raise the box temperature for about 5 minutes then switch off the fan. I keep my paint can in my warm office (70-75 F) shake ,spray, then after a couple of minutes put the fan back on for about 15 minutes. Part then moved into my office. Not a lot of electricty cost.

Calling it an office is a bit grand, it's my former fish house that is fully insulated with 50 mm Kingspan on all four sides & roof then clad in MDF about 30 years ago, small outside window & door is double glazed. Internal door to garage and widow single glazed. Heated by a 50 year old night storage unit on a 3 hour time clock on Econmy 7. In extreme cold periods I up the hours on the timer.

Post by: Orcade-Ian on October 31, 2024, 12:08:43 PM: Looks great Johnny,
Was that a local supplier? Could try it in Eddie Ratter or Colin Ross oven to see if there is any difference. I've been doing the lower edge of the door on the Mini today (pissing down of course) but I gently heat the cans and the panel until they have 'flashed off', just with a hot air gun - keeps the bugs from landing too! Don't do it while spraying though 👎

Title: Re: CB550 refurb
Post by: Johnny4428 on October 31, 2024, 02:57:39 PM: Yes Ian! Macgregors. I use the heat gun too just to heat item to be sprayed and warm up spray can too.

Never tried the cement mixer for polishing, Graham always does the polishing on the polishing machine. He also uses the wheel with a wire disc thing for cleaning all the threads out of bolts and cleaning nooks and crannies out of parts and awkward corners prior to sending for BZP. Usually about 20kg at a time that are barrelled BZP'd.

Post by: AndyD on December 17, 2024, 11:52:04 AM: I've had the larger version of the tumbler for a few years and it's certainly not a perfect answer but I have found it very good at cleaning up brackets and fixings if given enough time.
Also found that adding the tumbler liquid seems to help the process.
Seems to work brilliantly on flatter surfaces - brackets, large bolts, washers etc., less so on intricate smaller parts but that mat be down to the media type / size.
I've left them in for a good 6 or 8 hours and quite happy with the results - always dubious about leaving something running overnight but may give it a go one day when feeling brave.
Size of the media makes a big difference - I found that recessed bolt heads etc. weren't good but then got some much smaller cones and results were then much better - downside being they easily get stuck in any nuts or recesses etc.
Haven't tried many other types of media yet but I have got a bag of walnut shell for polishing and some fine glass blasting stuff which may be good for more aggressive work (but not great for the tumbler itself!).
Cheers,
Andy

Post by: Johnny4428 on January 30, 2025, 10:40:34 AM: So hereâ€™s the confession - after filling the carbs with fuel and quickly discovering I hadnâ€™t closed No3 carb drain screw 😡 I pressed starter button and turned over to nothing more than banging and cracking and misfire I quickly realised something is not right. I kind of ran out of time and left it til later in the day buying myself some thinking time. My instinct was to check valve timing which I did and resulted in the realisation that they were not set right. I had set the valves when I assembled the top end but had set the valves on the exhaust TDC stroke and not the compression TDC 🫢. Anybody tried that? Just me then! After setting them correctly all is well, fired up immediately and running well maybe try a carb sync see what like when I give it a right heat up. Slight leak at camshaft end cap mounting bracket. Is these aluminium sealing washers still available?

First start up rides always fills me with apprension, I remember one of my early runs on the 400 during its two cylinders only period (plug leads not in correct order) as I'm going up a fair hill the engine started to die. I pulled onto the pavement to look on my phone for breakdown recovery. That's when I turned the petrol tap to R, it flooded a carb, tarmac was stained, I thought for a moment it was engine oil. Rocked the bike, rode home on 2 cylinders. Wow was it a different bike when I switched the leads. Rookie mistake left coil to one & two, right coil to three & four. I beat myself up with that mistake.

So left with no choice but to drain oil and remove sump pan found that the sump gasket rubber is too thin for the groove! (I might be wrong) IMO. I thought about making a gasket to fit but thought Iâ€™ll try a thin smear of blue hylomer to see if that does the trick. Has anybody else found this?
Iâ€™m quite sure after checking that the mating surfaces were clean.
I wish I had the old gasket I could have compared the two.

I had the same problem a while back - can't remember now if it was the 350/4 or one of the 400/4s. I made a shaped tool out of an Araldite spatula and part filled the groove with Hylomar, then used the tool to leave a couple of mm of it in the bottom of the groove. Left for a few days to firm up, then used the gasket as normal. We are starting to experience the same problem that Brit bike owners have had for years, with aftermarket stuff not really fit for purpose,

Title: Re: CB550 refurb
Post by: Oddjob on February 07, 2025, 03:41:58 PM: If you had a new gasket and could measure the thickness I could compare to a genuine Honda sump oring and we could see if they are supplying thinner ones these days. I have quite a few genuine bottom end gaskets sets for the 500, around 6 or 7 IIRC, the sump gasket is the same as the 550 one, just stuff like the clutch gasket is different. As soon as you use it and it compresses I'd imagine it alters the thickness so measuring a used one probably won't work.

They are available to buy separately, 11398-323-000 which has been superceded to 11398-426-000, which is the CB650 IIRC. Cost about Â£10-11 plus P&P.

You can easily measure the existing oring and see if they make one that size. If not you can get some specially made but you need to order 500 as a rule. Theyâ€™d be cheaper than buying genuine though.

Thatâ€™s interesting Roo. I think the ring was thinner at the ends of the sump pan it seemed to just sink right into the groove, unless the groove in the pan was deeper at the ends? More investigation required. If I can get the drain hole threads repaired on the original I will fit it back on at first oil change. Itâ€™s in better shape than the replacement I put on. Might purchase an original seal from DS.

Title: Re: CB550 refurb
Post by: Oddjob on February 09, 2025, 12:55:42 AM: Cheaper and much easier to just buy a genuine oring Dom.

I could do with an old one to cut so I can measure itâ€™s length then measure the diameter of a new unused genuine ring to get that figure. Of course I had a few lying around and threw them away when I was cleaning up my collection of sump pans 😯😯

Just wondered what would be the best to do with them and indeed what other people have done. There is a condensate drain point on the air filter box and the same on the air plenum. And an inlet on the side of the air filter box for the now defunct carbon capture recycle idea from the breather hose. I was wondering if there was a problem fitting a short bit of hose and connecting the two condensate drains. Has anybody actually had any condensate with the breather bypassed to just vent to atmosphere? I am uncertain and slightly confused what to do. I donâ€™t have any hoses for these, I had a knackered hose from one of these, but nothing reordered till I find out what I need.

Saying that, itâ€™s something Iâ€™ve never done, they just donâ€™t seem to collect any, or maybe it evaporates during the summer months. As for the hole in the bottom of the air filter box, just leave it, itâ€™s not doing anything and it may help get a little more air into the box if anything obstructs the air duct.

500 filters last longer than 550 ones due to less contamination caused by the recycling system, what a waste of time and money that was, all because of California and itâ€™s anti smog measures.

Post by: Oddjob on February 11, 2025, 09:47:55 PM: Mine had the one way valve when I bought a new plenum from DS, was some years ago though, tbh I donâ€™t think Iâ€™d spotted it before till I saw a new one, the end gets covered in grease and crap and the last thing you feel like doing is squeezing that. TBH Bryan the one way valve is essentially just a split in a hose, closes up as soon as you release it.

Post by: Johnny4428 on February 11, 2025, 10:49:19 PM: So if I just plug the plenum one and leave the air box ones open that should suffice?

Could you not fit some cap ends on? A member here previously posted a link on blanking plugs that were on ebay in various sizes.

Post by: Johnny4428 on February 13, 2025, 03:51:59 PM: On the sump front most annoyingly it is still weeping a little oil. Discovered after giving the engine a good heat as I was balancing the carbs. I have now a Honda rubber seal from DS which I will fit either to the sump pan thatâ€™s on the bike or the original one off the bike that requires a thread repair on the drain plug hole. I will try to compare sump gaskets once I have the sump removed, will see how the thread repair goes.

Post by: Oddjob on February 13, 2025, 05:03:37 PM: If you need a sump pan Iâ€™ve probably got one or 2 spare, even got one ceramic coated in satin black with the edges of the fins polished 😀😀😀 matches the oil filter housing Iâ€™ve also had done.
Title: Re: CB550 refurb
Post by: Johnny4428 on February 14, 2025, 07:56:54 AM: Thanks Ken! Iâ€™ll see how I get on with the thread repair on mine. Like the idea of the blinded up pan and filter housing, barrels too? Iâ€™ve just gone for boring silver! 😳😂

Post by: Johnny4428 on February 15, 2025, 04:40:54 PM: Repaired sump pan threads with a helicoil today, filled pan of water and will see if thereâ€™s any weeping overnight. This sump pan is in far better nick than the replacement I bought off eBay. Only changed because of the drain hole threads. Provided all is well I will clean up and paint and fit with new Honda sump pan gasket/rubber seal.

Post by: Oddjob on February 17, 2025, 04:44:43 PM: Can I suggest an improvement Johnny.

The problem with helicoils isn't fitting them, it's removing the bolt after some time, sometimes the coil comes out with the bolt, meaning you have to do it again and each time makes the repair less and less reliable. This location however is ideal for never having to remove the sump bolt, just fit a Stahlbus sump plug, it means changing the oil requires no tools at all, less mess as the oil runs down a tube and in fact you can have the bowl located outside the engine instead of under it. You can in fact direct the tube into the opening of an old oil can so you can seal it afterwards, no more decanting old oil into a suitable container. You just remove the cap and plug and twist in the supplied hose, it's really simple, it's really reliable and I've had one fitted for many years now to my CB1300 and it's never leaked a drop. On engines where the exhausts are close to the sump plug it also means no more leaking onto them and the unpleasant cloud of noxious smoke when the engine starts and it starts burning off all that split oil.

Fit one, forget one and smile everytime you change the oil at how easy it now is. Make sure the thread size etc is correct, some kits for the CB500/550 are saying M14 but M&P reckon it's M12, M12 seems to be the right one IMO. Oh and no more buying sealing washers, you save money as time goes by.

Post by: Johnny4428 on February 17, 2025, 10:37:51 PM: I do like that drain plug idea, could drain directly into my waste oil drum. Definately will be getting one of them. As for the helicoil, I havenâ€™t had one done before on a drain plug so canâ€™t comment on the longevity. Good candidate for Stahlbus!

Post by: Johnny4428 on February 21, 2025, 03:53:26 PM: I fitted this DS master cylinder kit a little more than a year ago. But it has failed big time. Not just a weep but a pool on the floor in the morning. Not even riding the bike! I would say the rubber is a touch hard and donâ€™t like the fact that you can insert the plunger with little or no resistance. Bore in the cylinder looks fairly descent, so the question is where can I get a reliable kit from?

Post by: Bryanj on February 21, 2025, 04:20:20 PM: If its laid out as it was assembled it was done wrong, the loose lip seal shoul be aginst the piston and the hard cup at the very end
Title: Re: CB550 refurb
Post by: Johnny4428 on February 21, 2025, 05:06:54 PM: It was assembled the correct way Bryan, doubt if would have worked the way itâ€™s laid out there, it was just a pic of the removed parts. I ran the bike last summer with no issues and not a drop of fluid leaking, because I had renewed the seals and internals in the cylinder. The master cylinder looks to be in good condition for age, had it been otherwise I would have replaced it.

Post by: Johnny4428 on February 21, 2025, 05:25:18 PM: Master cylinder assembly complete, cheaper than an OEM master cylinder kit!😳 maybe a no brainer.

Post by: Seabeowner on February 21, 2025, 06:39:19 PM: I looked out CB500T kits.
They tend to be cheaper. Paid a few quid less than this.

Post by: Johnny4428 on February 21, 2025, 10:23:50 PM: Thanks for the link there, Iâ€™m going to take another look at the cylinder bore before I order.
Title: Re: CB550 refurb
Post by: Johnny4428 on February 25, 2025, 05:56:15 PM: After measuring the bore in the master cylinder which was well within spec, I ordered another repair kit. Picture shows bit of difference in the piston seal diameter.
