Title: HM323 Update
Post by: AshimotoK0 on October 27, 2015, 06:25:54 AM
Hi Got this back from DS

Hi Ash,

We expected the first batch this month but due to production problems never received any. Best I can say is hopefully before the end of 2015. They

Will be to the exact same spec as the originals, both inside and out.

Best Regards
David

People are always quick to criticise Dave Silvers prices, but I bet he's laid out a fortune getting these made, I asked him some time ago about getting a system made for 750F1, he reckoned it was in excess of £50k to get one to prototype spec, and he'd never sell enough to recoup the investment, which is understandable. Let's hope the 323's aren't exactly like the originals inside, many rotted out in less than a year and cost Honda a fortune in warranty claims!

I spoke to Mark at DS yesterday when I was checking on an order and I think he was talking 7->800 plus VAT I know CMS NL must be in the the throes of bringing out repro's too. Just hope it's not going to be another CB350F experience like Roy had. Pretty sure DS's tooling is their own though. I suppose repro'ing is the way forward for DS as NOS parts are gradually drying up and Honda keep discontinuing key parts ... like CB750K1 rear shocks that are now NLA. Just wish DS would give free delivery over a certain spend though, like a lot of other traders do. BTW if anyone buys Yamiya parts then internal shipping in Japan is free if your  spend is over 35k  Yen .. around 190 GBP (very easy to spend over that amount with Yamiya).

 good news that HM323's will soon be available (again),CMSNL used to have them till earlier this year,at about 1700euro a set,
about the corrosion,cast your mund back to the 70's and 80's.not only did bike exhaust rust through,but cars,I can remember
replacing car exhausts about every 30 months,

I feel the main cause was lead in the petrol,as it was deposited inside the pipes it started a galvanic action,and the pipes rusted ,

the HM323 on my bike are over 22yrs old,a little tired,but look good at 70mph plus !!!
just don't do short journeys,and try to get the pipes good and hot !!

That price is outrageous. It's not that long ago, you could have a new set (brackets included!) for around € 800,-. That cepok is to be boycotted.

Not mine. The exhausts on later models (like mine) were a bit thicker (1,0 mm X 0,8 mm). Source: Motorrad 13 1976 p.15.
The important thing is to avoid short rides and to check the little drainholes are still open. At the moment I have my set removed. I was amazed the exhausts are still so good after 55.000 kms. BTW, my first set served me 78.000 kms before I donated them to the janitor who was happy as a child with them. The second set now is still as new outside and I don't hear loose parts inside. So ride them hot, that's the secret.
What I don't understand is this: why don't sellers like DS and CMSNL offer the possibility to subscribe with a down payment? It gives them certainty and us a better price. And with more CB500s with HM323s fitted they'll have more loyal clients. And... it's fun too. Why don't they?

Not a bad price if you take in to consideration that these are the last NOS 323's available .

The OEM were double-walled (pipe in pipe), the replicates not, hence a slightly higher operation noise and instant temperature discolouration of the downpipes...

I'd do like to know if the DS edition features double- or single walled downpipes though...

 Hi, There are production issues which have resulted in all production having to be returned to the factory. Unfortunately no ETA as to when the next batch will arrive.
 
 


I will ask about double-skinning.

Those unchromed from 'coastpath' he got in a pallet of 'sell-offs' from CMSNL

That chromer he lists is interesting . Anybody know them?

Bit confused what DS himself  told me about the 323's being the same as CMS because CMS are available and DS has rejected a batch and no firm date when available. Why would CMS have them correct and not him?  I was told by Mark at DS that they are being made along side the HM341's at the same factory. Anyone bought HM341's from DS and can confirm double skinned or not. BTW he has some  'seconds' sets for sale of the 341's available discounted. Just wish Yamiya would start doing 500/4 parts

I seem to recall a member on here bought a set of pipes from cms, think it was royhall for his 350/4, and they were crap!. When he told them, they checked all the others in stock and they were as bad. Maybe D S. Is a lot fussier about quality control than cms.

Wasn't just the CMS exhausts that were crap it was the whole production run including those at DSS and a German supplier. To Silvers credit he pulled the entire stock after he found out about the quality and doesn't sell them now (except for a few oddments that he's selling off).

I re-asked the question and got this back:-

Mark (DSS)  is correct, the same factory is supplying the CB750K pipes and the CB500F. These will be the same ones that CMS are supplying but I haven’t seen them yet to comment on. I have been advised that they are same spec as O/E and am surprised to read from other members this is not the case. Once I have seen them I will be in a better position to advise on this.

Is this another case where if 'HM' was stamped on the pipes it would be a case of IPR infringement, as with the Honda logo on the back of seat covers?

I'm sure your right Chris about the 'HM' being an infringement, very sad if that is the case. I bet they will have 'HM' stamped on them for other countries.

And yes, your totally right, the move is next Tuesday. For one reason or another there are more new and used bike bits and associated paraphernalia coming through the front door than rubbish going out the back door. I will definitely need a bigger lorry !!!  :'( :'( :'( :'(

So 'James and Julie'  (sounds like the reading books I had at school)  ..oh sh*t that was Janet and John.... forgive me  ;D

What are the welds like?.. are they double skinned? ..whats the chrome like? ..where are the markings stamped ?... photos? How do they generally compare with the originals or late production oem.

Can't understand why CMS have them but DS don't if they are from the same manufacturer?

If they are OK I think I will hang on and get some from DS because I know that they will definitely let you return stuff if not happy. I know people who bought off CMS and had hassle returning stuff.

Post by: JamesH on November 25, 2015, 09:12:23 AM
First inspection is they're ok. Not Honda standard, but pretty good for the price.

Single skinned.

Welds at header / silencer interface seem good.

Drain hole in correct position and is larger than the oem hole by a few mm and isn't 'flared' just  a straight hole so probably less prone to blockage?

Marking convention is: CB500 'xx' 323 (where xx is IL, IR etc..).

The welded seams could have been finished better and do show some signs of 'serration' similar to the 350f pipes that Roy sent back. Not ideal but just about acceptable imho.

Pictures to follow in a few days...

Same old rubbish then. Serrated welds and single skinned?
DSS did say earlier that there were production issues, they are more picky than CMS about quality. I'd send them back, as they wouldn't do for me at that price. Although some may have no option but use them.

Must admit I am kinda agreeing with Roy.. something doesn't stack up as the HM341 factory DEFINITELY makes the  headers double skinned (look at pic previously in this post). How about this for a theory ... both CMS and DS have had production probs .. so CMS have, as an interim measure, got some from elsewhere.

interesting about double skinned pipes,

 I bought my set about 1992,all in Honda packaging,all with HM323 on them,
I have not had them off for a couple of years,but I am sure they are NOT double skinned,

if you check any photo ,all the pipes are blued,

maybe in the late 80's onwards they were into cost cutting ?
Title: Re: HM323 Update
Post by: AshimotoK0 on November 25, 2015, 12:43:31 PM
I think the way of checking is to see if there are spot weld marks near to the flange part of the pipe.

If find this all so bleedin' confusing ... I reckon those CMS pipes are 'stopgaps' till the DS/CMS ones are sorted out see below. The ones 'Coastpath' is selling must be prototypes of what's in the 'pipeline' from DS /CMS. SO both DS and 'Coastpath are saying double skinned but James's are single skinned from CMS?



Hi Ashley

Dear honda_four_rider,

Hi Ashley
They are double skinned - facsimiles of the originals as described.

QUESTION--------------------------------------------------------------------------------
From: honda_four_rider
To: coastpath500
Subject: Other: honda_four_rider sent a message about Honda CB500 to K0' K1 & K2, exhaust set - new #262168364375
Sent date: 07-Dec-15 13:17:37 GMT
Dear coastpath500,
Hi ... Could you post or add a link to a close up of the flanged outlet of the header pipe please so that I can ascertain if these are double skinned or not. The Honda OEM ones were definitely double skinned originally with 4 spot welds near to the header outlet.
Kind regards ,... Ashley

Hi Ash (again)
I can promise you that CMS’s headers are double skinned – I know this for a fact, I was working for them at the time of development and I asked an old colleague who still works there and he confirmed they are double skinned.
   
Cheers
James

Some mighty fine crocs in the shop next door too for a fiver !!  ;D ;D ;D ;D No worries about being out of stock .. I will wait for DS .. his QC & returns policy is better than CMS anyway, plus my mate in York has a trade account.

Pipes changed for K3 - so the 'tulip' end style of the pipes on earlier bikes are not correct for yours...the parts listed by DSS are correct...

I have a set  of 374 'tulip shape'  repros reserved paid for from David Silver but he's holding delivery as I have other parts to order and I only want to pay one set of postage. If they look OK I might take them the CB500 guru in York to let him appraise them. Evidently he told that DS had a go at reproving these a few years back and this guy had two sets but returned them as he said that on the 1st set the chroming was crap and on the second set they didn't fit properly. I have high hopes for the latest incarnation though as they are from the same source as CMS but hopefully with tighter QC and evidently the CMS ones are decent with double-skinned header pipes.

Hi, I got all excited by the news that these were back in stock. About 3 years ago I bought three replacements from DS but when I went back to get the fourth one there was no more stock! ( I know I should have bought all four together but funds were tight and I replaced the three worst ones ) Anyway today I dusted of my debit Card and phoned DS. :-\ Yes Sir we have these back in stock......but you can only buy a set of FOUR. The MAN was very understanding of my plight, but he has been instructed they are only to be sold as sets and that's it. They do have three, top left ones classed as imperfect they can sell, but as he couldn't actually see them to describe them to me I really don't want to take a chance.
So...........anyone need a set of three pipes, but not the left upper? I know, I know, it's a real long shot but............

Or is there a member local to DS who could have a look on your behalf?

Asked DS at his museum launch what the deal was on re-manufacture of the 323 pipes and he said it's CMS who own the tooling. I guess he guaranteed them a whopping potential order when they were getting tooled up to make them. Still can't work out why the first few batches he got, he rejected due to poor quality. Surely the Dutch didn't try to stitch him up with shoddy goods  ;) Please don't threaten me with 'yer rolling pin or some form of gruesome medical instrument for daring to mention DS in a post Julie  ;D ;D ;D

What is your problem with Dave Silver then Julie? He goes out on a limb to find parts, or have them re manufactured, parts that simply not be available if he didn't. Never met the guy, but on the phone he is very friendly and helpful, as are his staff. I think without him, a lot of people on this forums bikes would be a pile of bits in a shed, rather than on the road.

I have not got a problem with him as a person Hairy, never met the chap but would like to very much. I just get p'd off when you order parts, they send the wrong parts and then make out it's your fault. It's the business practices and ethics that I don't like. I agree with you though, we would all be in the poo without him at times but luckily he's not the only supplier of Honda parts so my money would go elsewhere firstly and DSS as a last resort.

I'll come clean ..he was the guy who sold me my 'dealer take off' seat for my 500K0. Without him, I don't think I would ever have found a seat like that in my lifetime ! It wasn't cheap but he gave me 1st dibs. When you see the number off staff he has, he must have fairly high overheads. Surprised at his dealings with you both though Julie. I once ordered a CB750 front guard and there was a slight blemish in the chrome. He had a carrier pick it up FOC and return posted the only 'perfect' one after going through 14 he had to get one that good. This is before I had actually met him in person. His only worry at the time was that if he complained too much to Honda, they might just delete the part ...like they did with 750,500,400/4 genuine pipes and 400/4 seats.

Hi All ,

Today i dismantled my newley installed replicas HM323 to carry out some work on my bike.

I noticed when I dismantled them that they have soot at  the rear around the bolts which you tie the brackets to. Not too much but Obviously for me these are leaking from this place. I shall post pictures tomorrow of these.

I do not think that any seal should be installed there? Also has anyone experienced this ? Is this also on the original ones ?

I have only yet covered 200 miles since my rebuild.

When I fitted my set of repro's I had exactly the same issue. I contacted CMS, they were surprised and asked for pictures, and after a couple of days they came back to me with an answer.

The old ones used to do it so the new repro ones do!! Ha ha.

I was told that I could either 1. Seal it around the stud area with exhaust gasket glue sealant stuff (exact wording!!) or 2. let soot from the engine seal it over time.

I opted for rubber o rings placed over the studs, pushed right up against the exhaust. Seems to have worked with no issues, probably done around 400miles since fitting.

Think I will get mine out of the loft, bung up the drain holes and and outlet, pressurize and see if they leak, better to seal before they have been used than after running them.
My new 400/4 headers (Gen) came with silver painty stuff on the welded joints ... 'bikepusher' agreed that this was how they were on a few NOS sets he's had. So his input/contribution was indeed useful on here before he threw his toys out of the pram   ;D ;D.

Sorry I misunderstood, do you mean around the clamps? There should be a copper /asbestosy crush seal in there, plus there can  often be  one or two old crushed flat ones left in there from previous exhausts.

New 500 pipes used to have the silver paint around the stud area as standard. Maybe it acted as a sealant until it coked up around that area? I also seem to recall it was where the downpipe and silencer met as well.

No silver paint on the NOS ones I got from you around the pipe to silencer, only round the bolts and a little dribble out of the drain holes.

Last year I bought some 323 pipes from DS. Today I failed to fit them. I have existing brackets that although a bit rusty were fine on my old set. The RHS were a bit of a struggle, but they are on. (and nearly aligned!) The LHS are a nightmare. There is no way I can get the balance pipes at the rear to anywhere near line up. Tweaked the bracket for hours. Anyone else have this problem? I'll order new brackets, but don't hold out much hope.
Title: Re: HM323 Update
Post by: Seabeowner on April 14, 2017, 04:49:08 PM
Well they're on. A cup of tea helped followed by some more bending and twisting of the lower bracket. Not perfect and the bracket is a bit of a mess to look at, but at least I've a bike on the road. And louder than I expected.

I vaguely recall having the same issue when I first took my exhausts off my brand new 500, I turned out I had re-installed them incorrectly, one bracket goes behind the footrest hanger and one in front of it, I put them together and this caused the back end to miss align so much it was a real struggle to get the balance pipe on, once I figured out what I'd done the were fine again. Check the position of the brackets is my advise.
Same here. To check your brackets the photos in this post are very helpful: http://www.sohc.co.uk/index.php/topic,10228.msg73340.html#msg73340

Done it, and the set I fitted lined up perfect with both brackets on the front of the hanger. The PO had tweaked them that much, the pipes would not line up with the brackets on the right way.
