breaks up at high rpms
i have a xr100r that i have built and it makes power all the way out to 12000 rpms and will turn 14k in high gear pulling top speed with stock cdi box. i figured i could buy this box and maybe get another half horsepower or so but it starts breaking up really bad around 10k and wont turn up past 10500. dont know if they are all like this or if mine is defective but i definitely wasted money on this purchase.

Does not work for 2008 CRF150F
I have a 2008 Honda CRF150F. Maybe the product isn't bad but the description is. It said it was compatible, it is not. It blows the starter fuse everytime. We made sure the battery was disconnected and everything had solid connections. Does not work for CRF150F. It may be a good value and good quality but I never got to try it out.

Very worth it, compared to competitors prices is even. Matched my big gun pipe well.
