I just found something that will put back my CB750 from running even if I do establish oil pressure this weekend, I need a new / secondhand carb plate. The alloy plate that often cracks is fine, but on top is the bar/ quadrant that opens the carbs. One of the forks that go round the carb slide has broken, probably fell off the shelf I n storage, though no ones owning up, but I don't know, anyway it needs replacing and the whole $&@?/ assembly is one part!
Of course it's no longer available, not at Silver or CMS so I need another. However as my carb plate is fine then a broken one would be fine, I only need the carb opening bit. Part number is 16035-300-004, helpfully called plate set, stay.
Can anyone help? , there's one on flea bay I found, but it's in Nebraska, so the usual hassles with shipping, duty etc.
ETA Found a job lot of CB750 carb bits in Towcester that look right, including the bit I need. I can't see any differences, but I need to get the bits from the garage to study the photo, i hope there were no significant variations.

I don't suppose that it is of any help, but I have a complete set of CB350/4 carburettors with all linkages, fittings etc. that I bought in case of need when I was readying my own bike for the road. I do know that some of the internals are missing from the carbs though.
Is there any chance that the part that you are seeking might be the same across the range?
-
I Have a broken set of carbs at home i'll have a look tonight and see what that part is like
-
The only picture I can Google of a CB350 plate, the plate looks similar but the shaft looks shorter, I think the carb opening mechanism is different, but thanks.
RGP750, is it a CB750 set? The bit I am after has the fingers that pull open carbs 1 and 2, its fastened to a chrome shaft.
The ebay set in Towcester is http://www.ebay.co.uk/itm/262596843703 however I don't need the carbs, and the alloy plate looks to be slightly damaged, there's only one picture. However it does't matter as long as the opening part comes off the shaft OK.
-
Yes a 750 set
-
If you mean the circled bits here I have one side but can't remember which one. The carbs on it were 064's
The seller in Towcester BTW is the guy who runs DS's museum. Bought a few things from him and always been fine and reasonably priced. He is ex-Honda UK.

On your photo, Ash with the open prongs of the forks facing towards you, it would be the left hand set circled in red.
From what I read on here, in a thread Richard started way back, they are not meant to come apart and can be a sod because they are held on by hardened pins.
I have emailed they guy in Towcester for more info about the set he has, or better photos.

Hi, just back from the garage, and your right, it's wrong. :(
Thanks for looking though. There's still Richard, otherwise we'll see what reply I get from the Towcester guy.

I reckon you could get quite a bit from selling the bits of those Towcester carbs you don't need if the bodies are OK
-
It might be worth trying Van Gerben to see if he has a replacement plate: gerbenhilly@hotmail.com

Hi Dave those carbs were in a job lot of parts I sold to Roger the guy from Towcester, they really are only suitable for spares, I can't remember if the carb plate was damaged or not ? but most of the chrome parts were badly rusted and pitted and one or more of the float posts were broken , cheers Mick.
-
Sorry had to go out last night so will take a look tonight.
-
I wish I'd seen your post earlier Mick, as I now own your old carb bits! What model CB750 are they from?
Broken float posts and rusty choke linkages etc don't matter, I only really need the carb plate and opening forks, they look OK other than a bit of rust, if there are any issues with the backing plate I'll get the pins drilled out if necessary and reuse mine. At the end of the day its that one part with the fork I want, and there aren't any other options available right now.
The rest of the bits will go in an ever growing collection of parts to one day ebay / autojumble.
Can anyone tell me where to get the 8 O rings for the carb T pieces between the carbs, without buying a full carb gasket set?
-
I have the 'O' rings in stock Dave
-
I got my 'O' rings from Yamiya ..... Maybe Gerben in Holland might sell them separately. If I get a chance I will try to measure my Yamiya ones and identify the size. Unless Trigger knows already !
Whoops on the carbs.. If the plastic floats are OK you should get reasonable money for them. Or do what I do with DK .... if there is obvious damage inside, have a moan to the seller about float-post breakages rendering them useless. I met him at DS's Museum launch ..seemed like a reasonable guy with a reputation to keep. The spares guy at DK told me their remit from the boss was 'on all accounts do NOT upset Mr eBay'
-
O rings ordered from Trigger, along with new discs for the carb tops.
-
Sorry keeping you in suspense. i think this is what you want.

Looks like yours are broken too, Rich, but at the other end. With some drilling out of pins I could've made a good set with those, but if I've bought a whole set now I'll go with those for now. Thanks for looking.

Drill what pins out ? NO drilling to get any part of the rail apart.

According to eBay, it's too late to cancel my order, although the parts have not been marked as shipped yet.
-
Try contacting the seller and see if he can do anything for you.
If he is as helpful as others have suggested and hasn't actually sent the parts yet he should be able to cancel.
-
The parts are still marked as unsent, I have asked if I could cancel as I don't actually need the carbs, and told him to deduct any fees incurred and accept my apologies.
Rich, I'll send you a pm.
ETA: Roger says no problem to cancel he's been away & couldn't respond to my queries. Harder than he thinks as eBay only lets you cancel for 30 mins.
