Your cylinders bored to fit.

Boring a cylinder needs attention to detail, if it is going to be done right. Here at Full Bore we take every precaution to make sure it is right and will custom size to what your needs are. Our strict quality control policy ensures specifications will be met. The cylinder is bored, sized, and followed by a three stage chamfer to ease the rings back in and increase engine life, and final hone for the proper cross hatch and finish.

Full Bore Platinum pwc engine rebuild .

The difference Is the attention to detail and the Quality of the parts.

These aren't SBT remans and we don't and won't use SBT parts in anything we do.

Take pride in your ride with our Platinum rebuilds.

Our platinum engine rotates easier and produces less friction. This results in less heat, less drag, and more Horse Power, while increasing the dependability.

All of our engines are built to last and we stand behind them, with a warranty on parts and craftsmanship. Our Platinum engine rebuild now comes with a 2 year warranty.

Engine rebuild kits.

Need more than a top end kit but don’t have the time for Full Bore to do the complete rebuild and don’t want hackmasters with false claims and shoddy work doing it. This might be the Ideal solution for you.

The hard part for the guy at home to do a "QUALITY" engine rebuild is getting a good crankshaft and cylinder boring that is even close to acceptable . We eliminate these problems with this kit.

We bore your cylinders to match new pistons. Currently offering kit's with WSM platinum Pro X Wiseco or Wossner pistons. Your rave valves (when applicable) are trimmed for clearance. Your cylinders are returned with new pistons, a complete gasket set which includes crank seals, and a brand new (not rebuilt) crankshaft.

If you send your old piston and spark plug, we can usually tell you what caused the failure so you can keep this from happening again.

Please note old pistons and spark plug will be disposed of and not returned.
