Yes it's a shame the bike is sound, recent tyres & battery. Just lost patience with it, needs a fresh mind.

Cable's fine, slides close correctly, I've had enough, at my age life's to short to waste on this. I will put it on classifieds for any member here before it goes on the bay.

Thanks so much for your reply, it is so frustrating, I have checked over & over all the points you raised, timing, a/r system etc.. Just at a loss now, back to the drawing board.

Carbs have been ultrasonic cleaned repeatedly with heat and carb. solution, no difference. timing re-checked, auto advance checked. Any more suggestions guys?.

Thanks

Thanks for all your constructive replies. Have ordered a decent Ultrasonic cleaner & solution so hopefully it should be sorted.

Yes I saw that post, didn't seem to get his problem sorted. I've been over everything I can think of over & over without result. very frustrating.

Thanks.

Thanks for that, just can't understand why it runs fine until it gets warmed up??. When warm it takes probably 7-8 secs to die down, nearly stalls then settles to perfect idle.

Are you sure this is the problem?, the carbs have been completely stripped down, jets cleaned, settings checked. If I am sure ultrasonic cleaner would solve the problem I would buy one, which would you recommend?.

I have a 1981 XS250, the problem is the revs don't drop or drop very slowly when revved. It seems fine when first started but as soon as it starts to warm up the problem starts. I have thoroughly cleaned the carbs twice with air line without success, diaphragms are ok, it has good compression, timing good with good spark at the plugs. I fitted new manifold rubbers and can see no leaks elsewhere. Any suggestions will be much appreciated before I put a light to it.
