Didn't replace the exhaust yet! I usually only do one modification at a time so that I can easily trace problem. This popping problem, is just after changing a few valves shims and removing the switch valve. I would like to correct the popping problem before going further with other mod, alough I already have a mod plan in the same line as wolf grampsizing, actually more scooterizing, but with my own twist. Îll let you know when îll get there, but in the meantime can anyone suggest a solution for the popping on deceleration?

Robert mon amie ne vous supprimez l'échappement ?

if you removed the exhaust then you might have to tighten the bolts at the heads. I had the issue with a bit of backfire on deceleration and that cured it, if not then you might want to grampsize the carb. I'll pm you the info. Give me a few minutes.

Just remove the afterburner tubing on my drifter 800, as many user suggest, and by following the instruction carefully. Many people claim that this will make the engine and exhaust run cooler and in many case decrease popping and backfire on deceleration. My motorcycle never had popping and backfire problem, but since i' ve done this modification it does! Did any of you encountered a similar effect?

Thanks
