Yes, also check around the muffler clamp for air leaks, although up at the head/port is more likely.

Air leak in the exhaust. when you decelerate it goes, "pop, pop, pop," and if you hit the throttle it stops.... Right?

I bet your exhaust washers need replacing on the side that is mumbling OR, you need to tighten the exhaust nut to close the air leak.

YES,

POP POP POP POP, when i decelerate, and stop if i hit the throttle.

But i don't think it is an air leak from exhaust system; it is very very thight.

Thank you

Piero

change the sealing washers at the exhaust port and it will go away....
