Shannon Clem runs the shop with his father and has been building Kawasaki's for years. PH 317 523-4049.
My motor has J & E 13 to 1 pistons with stock bore, race valve job and head porting and valve springs. Removed the 2 balancer shafts, reworked oil pump, low clearance oil pan. After the motor work I had Ryan Schnitz build the motor only and nitrous maps. I have a BMC air filter and a Brock's 4 into 1 system with a street meg. If you need motor work, check out OSR. They offer great work at a very good value and they are building some very fast motors!
What kind of power is that bike putting down with those mods? I ask because I also have an 06 and wonder how a modified first gen motor compares with the new version
