All work is guaranteed!!!

After we receive your cylinders we will inspect them and determine what oversize pistons it will take to make the cylinders straight (usually 1st or 2nd over) then bore your cylinders on a boring bar, final sized with a rigid hone.  The ports are chamfered in a 3 stage process to ease the rings back in, including a final hone to extend engine life, and improves performance. The kit is returned to you with everything needed for your top end rebuild

No more trips home from the machine shop without your cylinders because the pistons weren't big enough to clean it up.  Let alone the fact you have to send those pistons back and order another set.  We keep it simple and offer solutions for your top end rebuild and get you back on the water.

All cylinder work is done here at Full Bore.

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 and not returned.
