Got a chance to put a few miles on the 351, wow what a difference.Lotsa low end torque and power all over.I would definately rate the 351 kit way over any mods/add on out there.Feels like its got twice the low end grunt, just have to break it in now!!thanks bill for the great kit.

 

Cant wait to get the 331 kit for my 2012.....make me not regret passing up a wr250r!
