For the 2008 models, Kawasaki finally corrected the problems associated with the 07 and older output shafts. If you have an 07 or older model and are splitting the engine cases to add a stroker crank or do other mods, we highly recommend replacing your output shaft at the same time. We are very confident in the quality of this new output shaft and thus, will warranty it for a full year if purchased directly from us.
