There's no substitute for displacement when it comes to raw power, and the best way to increase displacement is to increase the bore size. Kustom Kraft's Big Bore Kits are just what you're searching for. A Kustom Kraft Big Bore offers the most reliable way to get the power you expect. In most cases it's just bolt it on and tune the carb and you're off to the races (after break-in that is). Another advantage of doing a big bore kit is when your cylinder is fried a big bore kit becomes a no brainer.

Just pop your cylinder off your bike and send it to us along with the printed work order form. You'll find the link to the order form in red above Fill it out completely and put it in the box with your carefully packed cylinder. Don't forget to remove everything from the cylinder that's not needed for modification.
