Made my 2014 sxf 350 pull nice. Id give it a 5 but the only reason i didnt is because it really works much better with a jdjetting tuner of something similiar to really make it shine! Nice power at a lower rpm and "lofts" the front wheel easier now. Nothing negative ro say about thw kit whatsoever! Was going to get a 450 but was cheaper to try this and glad i did! Still not thw torque of a 450 on bottom but pulls great and does not sign off early....just keeps pulling.Read All Reviews

Excellent results, I ride single track at 7,000' + elevation. This has proven to be a very good addition to an already excellent machine. Gettin a two stroke dialed in at high elevation is no easy chore. The HC head has helped alot. Throttle response has increase considerably as well as usable tork. I am getting much more carry out of each gear. "GREAT PRODUCT", at a reasonable price.Read All Reviews
