How Would You Like 15% More Low End for Your Suzuki?

Then we've got just what your looking for. Kustom Kraft Performance has been designing and building Big Bore kits for over 40 years. Our Suzuki Big Bore kits can produce up to 30% more displacement and 30% more torque and the best part is they totally reliable. The horse power gains are mostly in the low RPM range and not wholly above the redline like some other modifications.

Not sure you can handle the wrenching task? If you can rebuild a top end you can do the big bore kit. Here's how it works. In the case of most 2 strokes. Tear down the top end and send us the cylinder, cylinder head, and exhaust valves if any. For 4 stroke models all we need is the cylinder. Be sure to print out the job order form and fill it completely. Carefully pack your parts so they don't get damaged in shipping. Send them to us along with the order form. We will bore out your cylinder and re-plate it or sleeve it as needed. We supply all the special big bore parts such as piston kit and gaskets when needed. Complete instructions will be included.
