I have been lirking around and reading stuff for a while and found some really good information. Thanks for everyones contribution. Now I have a question:
I have an 06 Speedy with TB pipes. Recently I installed K&N filter, removed the snorkel and AI, and rejetted(just main jet). I notice now that I have less power through the middle than I had before and now I get a pop under my seat when I crank the throttle from idle. Anybody ever get that pop(explosion) or know how to fix the middle power loss?
