2nd test ride... new problem

[Dragonslayer]

OK The brakes are blead and now feel fine. I just took the second test ride and it is now back firing just a little bit on the # 3 and 4 cylinders when de- accelerating any hints on this new problem?

[utadventure]

you might be running a touch rich?

Usually, "backfiring" as loud explosions in the exhaust is caused by either leaking exhaust/muffler connections (allows air into the hot rich exhaust that then combusts) or sticky carb slides or carbs in need of synchronization.

BTW, how do you know it is #3 and #4 backfiring?

I said 3 & 4 because it seems to be backfiring from the right side (as your sitting on it) exhaust. That is also the side there is a possiblity of a loose exhaust pipe connection where the muffler connects with the exhaust header.

I suspect you found your problem.

Must have cause it seems to have gone away with the help of a little foil tape on the exhaust header for thickness and a minor adaptation on the clamp which allowed me to tighten it a little more.
