Stage Two 120cc Cyl. Kit for XR100's 
The EO Stage Two kit is the most complete and well engineered kit on the market. Sure, you can stroke them and use higher compression...but did anyone tell you the about the dark side?  If you build your motor past 120cc or use one companies cam and someone else's piston kit, and maybe someone else's head... you bend valves, break cranks and shear off kick shafts. We know how far you can push this little motor and still have it live through your kids childhood or your couple of seasons of racing backyard Supercross! (Mom, Dad stole my bike again.)

 

Includes: everything in a Stage 1 kit plus 1) Camshaft (exchange) 1) set  Valve Springs and Heavy Duty head nuts "NO CASE MACHINING REQ."
