popping and banging

Post by markymark » Thu Nov 26, 2020 8:15 pm

hi guys its me again about my carbs
(right hand carb as sitting on the bike)
as i put in my other messages my right hand carb is popping and banging when i try to rev it up but fine on tick over.
so i tried other peoples suggestions. i have changed the inlet manifold o rings and rubber carb mounts and jet kits on both carbs, i even went as far as replacing the
cyclinder head and the timing and cams are spot on and i mean SPOT ON.
if any one has any other idears then im all ears...........

Have you tried swapping the coils and plug leads over already?

The small white/cream coloured plastic cover on the outer side of the right hand carb will get very small cracks in it as it ages, and this will cause popping/backfiring. I glued up a crack in mine which solved the problem. I don't know if the same thing happens to the on on the left carb (in between the carbs).
