like ciao said its a BITCH to remove the header restrictor on this pipe but with a dremel and some hard work it'll come out. the pipe makes insane crazy power at 9k+...definitely a ripper. im running it on an doppler 50cc kit / clutch pulley setup and the thing absolutely destroys with a tiny 15mm amal carb (lol)

Faster than a ninja

taco eater :
Ciao from SF
Took my old 103 racing engine, put it on a new frame, swapped out the old ninja G3, didn't tune it, didn't change anything and gained 5-10mph at least. I'm not even sure what will happen once I tune this thing. The mounting is easier and has more space than the G3 too, Only down side is drilling out the restriction is a total pain, it is thick and seemed like it was welded all the way around, you have to hack and pull at it to get it out.
insane power
