I'm not asking anyone there opinions on my engines or how they run I simply ask if anyone else has experienced the same results as I have as far as the expansion chamber NOT making any noticable power increase over just having a good free flowing exhaust on these china girls.

I'm very good at tuning these engines so I'm not looking for any advice in that area.

thanks for the words though

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
