Yambits. For the silencer rubbers not sure about the sync screw washers.

Guess you mean the medium size rubber that fits on the main mounting point, that is available gen Yamaha from Fowlers, as is the rear rubber bung.  Very generally, the gen rubbers are good quality, pattern ones are a mixed bag.  The "carb sync screw washer" is strange.  What washer is it that you mean?

its the rubber seal from downpipe to silencer, and the washer is the one where you undo the screws ro view the dimple on the slides to balance the carbs

RD250C doesn't have a rubber joint, unless you are using 400 downpipes and silencers? If so, Yambits seem to have a kit, unless you find NOS.  The Slide viewing blank washer is also unavailable.  I don't see a Yambits one?

If the washer is part number 256-14956-01, then Fowlers have plenty on ebay.

If it's not, please accept my apologies and I'll butt out!

Hi Al, well, the 256-14956-01 is a copper washer that is not quite the same as the alloy original in look or fit.  I should have said.  You can get closer to the OE with cheaper special alloy washers off ebay but, I have not found an exact match.  OE is about 1mm thick and very narrow with a non standard I/D and O/D.  Cheers

Thanks for everyone's help i don't think they are 400 pipes but i could be wrong?
They  have a castellated collar nut joining the silencer and downpipe together and underneath that is the rubber type joint im looking for if still available anywhere?
Thanks for the help guys much appreciated

I used this gasket, http://mad4bikes.co.uk/exhaust-gasket-seal-45-3mm-id-50-0mm-od.html   cut in half, to make two for my 250e.
Your size will be slightly smaller so you will have to measure the tubes.

Aha! Yes, the castellated tube nut join is 250.   :)  Unfortunately, the seal that goes inside is a special hi-temp plastic that is not available as a dealer part anymore.  NOS are rare.  The pattern versions are a mixed bag AFAIK.  Anyone found a good pattern part?
