Yeah, i' m running it for about 1,5 years now works perfect.
advantages: somewhat faster( feels ALOT faster lol) works best if you're engine is already free'd from restrictions, loves high rpm( because of cdi mapping)very good throttle response, it's somewhat exclusive,
Disadvantages: doesn't fit straight out of the box had to make a base plate myself(old aluminum dirtbike rear sprocket lol), NO woodruff key, no light coils
