There is no replacement for displacement

750cc big bore puts you in the neighborhood of 86 ft/lb. torque and 140hp at 8600-RPM with pipes, reeds, trail porting, and boost bottle kit.

Where your see the most improvement is not at peak but in the bottom-end, increases of 30-40ft/lb. torque and 40-50hp at 6000-RPM.  $475.00(Parts Only)

Our custom porting and head work adds 10-14hp and 6-9 ft lbs or torque to your sled with “stock” reliability. Through extensive testing on our shop sleds, we have found a balance between high horsepower and reliability. All porting is hand profiled and headwork is CNC machine cut to maintain proper squish band and volume. Beware of just flat cutting the head to increase compression. You have to re-cut the squish band also. We have recognized detonation problems through testing, caused by not enough clearance at the outer edges of the squish band if it is not re-cut. Porting starts at $650.00


Big Bore Kit
