100% new parts. Mild porting, MX cam, careful assembly with synthetic lube, high quality seals, cam sprocket, hardened cam bolts, SS exhaust studs, 52/54mm gasket set. I even lash the valves. Bolt on and rip performance. If you run it, and don't like the performance, I'll give 100% credit towards a new TB Race Head. $125, with free shipping of course!
