Have excessive popping when let off throttle. All air leaks have been addressed. Any suggestions
[img]smileys/smiley11.gif[/img]get some reversion cones and put them in the end of the pipes...this will eliminate the popping noise
reversion cones belong no more than 4 inches from the exhaust port ,,, otherwise they are just a differant looking baffle,,, careful what you spend your money on
by looking at the other thread 1hydroman has it has torque cones/reversion cones already at the port end of the pipes and baffles at the noisy end ,may still be a little lean.
Have you jetted your carb Typically a Drag pipe (aka, straight pipe, shotgun pipe) will have a bit of a bark on decel, but this can be minimized with a good jet kit and turning in your mix to lean it out some.
