Desperately Seeking!! / Brake splitter
« on: October 06, 2023, 10:38:44 PM »
Evening all, anyone got a spare front brake splitter in fair fettle that they need relieving of?

I think the 400 is the same as the 550,500 etc but haven’t cross ref’s the numbers yet. There’s some on flea bay but all too dear or a bit passed it so thought I’d ask here and see if anybody had any treasure??

Other Bikes / Roo's Viffer
« on: July 13, 2023, 10:24:41 AM »
Well I hoped to be posting a few shots of a sea of bikes at Squires Milk Bar at Sherburn in Elmet, last night but sadly, Houston, we have a problem!

The first time in 21 years Rosey has stopped a journey through failure!

Just got through Boston Spa, opened her up on the nice fat A road and a plug gave up and she started to pop on 3!!! Bugger.

Limped 22miles home on three pots and currently trying to find 4 plugs to get her fettled for the long ride home. Naturally these are the hardest plugs in the world to find unless you want to spend £29.40 each on them………..nope not I!

Found three, just need one more!

Bit of a worry as it’s either a plug or a coil……. Hoping on the former rather than the latter but a poke about will no doubt identify the issue……..fingers crossed!

Desperately Seeking!! / Rubber
« on: June 26, 2023, 09:55:57 PM »
Evening all, I’m just cutting bits of ally up to have ‘snotted’ together at the welding place down the road and been looking for rubber blocks, door stops, lumps of this n that to attach to the bracket I’m making, to use as a stop for the centre stand. Blimey it’s dear!

Would anybody have a lump of rubber block between 15-25mm thick and about 25mm square?

Just trying to avoid spending 8 quid on a Matt to cut the corner off and forever for it to be in the way until required for a job and by which point it’s knackered! I’m sure you’ve all been there? “I’ll keep hold of that as I reckon it’ll come in for something”, go grab it 6 years later and it’s shagged out and you bin it

Soz to be on the scrounge but cash flow has been crap this month and still skint 🫤

Went to get a ticket on the VFR today and the tech who did it was 21 and the owner of this little beauty. He passed his test in it and parked it for three years to get some dosh together.

He reckoned he’s spent £30k on it but it is quite frankly one of the best ones I’ve seen.

One for you Ted.

Cut slicks, 1380 motor, Koso dash, leather interior, the lot. Carbon bonnet and a super slick engine bay. He was just in the process of fitting a second rad as it was getting a little warm but what a great car

CB500/550 / Strange coil faults and sparking???
« on: May 22, 2023, 08:34:01 PM »
Hi after a good fiddle at the weekend (leave it Phil), and a tuning sesh getting the 400 sorted for the Boss, I turned to getting the 550 running a bit better. It's timed spot on, both statically and when running last weekend on 4 pots, done dynamically with good results. Valves done,carbs balanced, again last weekend when it was on all 4, and although kinda set up, needs finisheing off hence the twiddling yesterday.

I set everything up and it started with barely a touch of the button but only on 3 (2,3,4). Ok, pipe one cold, all other pipes nice and hot and all sparking with a test plug in each HT cap in turn when touching the head with the bare plug end, as you do.

So I have 2,3 and 4 all doing good and spot on so I take the plug out of cyl 1 and touch it against the head and press the starter.......nothing!          That is until I move the plug away from the head by about an inch and get a big long blue spark??? I number all my plugs with a marker to keep diagnosis easier should anything like this arise so I tried another plug and the same result, interesting!  Everytjing else behaving as they should and showing fat sparks on the head when touched while hitting the starter.

I then go accross all four HT leads doing the same thing and all are fine except when trying number 1 which then promoted the 'obligatory' wiggling of wires and leads to try to see how intermittant and where the fault might be coming from. Same results.

Went for a brew and a thunk after a small consise Anglo Saxon retort, as expected!

Went back out 10 mins later and preceded to do it all again except this time all four plugs were doing as requested when touching the engine and showing good spark, huzzah thought fitted all four after a second check and all looked spot on, HT leads back on and press fire..............3 cylinders except its 1,2 and 3 this time so the fault has jumped from 1 to 4?????     EH, how queer! ???

Do the whole process and the number 4 plug wont spark except about an inch away from the engine and you get a good arc! and as I was reminded, a good nibble if you catch yerself on it ;D ;D

Another wiggle and a prod, all four sparking so re fit, press go..........3 cylinders again but now its 2,3 and 4, so it's gone back to number 1!   I did this several times and always it would swap over for no reason.  STUMPED! ;D

Yes, the coils have had the 'Ash mod' and tested well afterwards so was happy with how they ended up afer the refurb which was done as the OE leads were so battered they just hung limp when you held them up and were snapped in various places. Anyway, questions, questions...

I realise there's nothing mechanical in the coils and nothing moves so I can't even picture this fault and how it might be happening or the reason why it might be swapping from primary to secondary coils, if I'm gettig that reasonably right?
 Has anybody had a similar fault or heard of anything that might be somewhere near a similar event that might explain it or promote it. As its intermittant  fault it's hard to pin down and especially when I have no 'concievable' way of thinking why or how it might be happening.

Me annd Ken had a chin wag the other night about it and he's stumped also but one potential thing to look at maybe is the engine cases behind the rotor plate of the points, possibly  There might be some cerekote on the end of the cases that might be breaking contact with the points plate and the motor? Probably not but I'll do the easy checks first before firing the parts canon or removing stuff,
Condensers were also mentioned and a test wil be done on those  whilst I'm at it but for the most part we were clutching at straws and a bit lost.

I'll have to get another coil set I think but I'll swap the blue and yellow wires to the current set and see if I can replicate the events but even if I can I think the safest bet is to buy a new set.  I would still like to understand how it can jump from one side to the other at will, all sparking outside the motor  but not when the plugs are back in the motor. Just a, well,  really odd one.  :o

Sorry about the epic but it took some describing...............

CB350/400 / Timing advance
« on: May 09, 2023, 09:04:37 PM »
Evening all, working on the 400 tonight getting it ready for the road and knowing I had to set the timing etc I set about it.

I’m having a real faff getting the test light to come on anytime before the T mark on rear plate, it simply won’t advance anymore. Any ideas?
Valves, done, cam chain, done. Points, done, just can’t get it timed. Any thoughts on my stupidity?

CB350/400 / Clutch cable guide
« on: May 03, 2023, 10:37:51 AM »
Could anyone tell me the DEFINITE place for this clutch cable guide, I just can’t remember and after trying to put it in various places, apart from the fact it fouls the tank I can’t for the life of me remember where it went and how. Sadly don’t have any shots in the camera from  disassembly to give me a prompt…..
Any shots gratefully received

Desperately Seeking!! / 400f front mudguard
« on: May 01, 2023, 04:28:32 PM »
Hi all, anyone got any spare, slightly knackered front mudguards? Just the guard not the stay,?

The one I’ve just started working appears to be badly holed under a raft of crap repairs.

Not a biggie, just don’t want to order a new one to then cut it up. I only need about 9” from the front of the brace and about 9” back.
It’ll get nannied and prepped for paint so not bothered if it’s a bit dinged and beaten up, if it’s summut near, yes please.
