I know exactly what your talking about. Got the Yoshi today and installed it along with the first oil change on my FZ8. I absolutely love it! R77 is just what i was looking for, not too loud nor too silent. I actually don't mind the popping either. I'm coming from a Ninja 250 with a Yoshi and it used to do the same thing on that bike so it's nothing new. Now all I want for now is a fender eliminator and the engine protection cage.
Just out of curiosity, is there any how to's of blocking off the ais? Just in case for some reason down the road I decide I don't want to hear the popping anymore.
