We are introducing our new ISR Race Legal Performance Head and Carb Kit for the Yamaha Snoscoot and Arctic Cat ZR 200.
The head has been CNC ported for better air flow and machined for higher compression. Add stainless steel valves and light weight valve spring retainers along with a PZ22 Walbro Carb and Filter and you will see up to a 2.5 HP + gains and significant increase in torque over the stock engine. Kit includes head gasket and instructions. Part # GYR-E1121-10
