We can repair most cylinders with a steel bore by boring for over-sized pistons.

We can Bore & Hone any cylinder, including cylinders with a steel liner in them.

How It’s Done

When we receive your cylinder we measure the size it is now, look over the general condition, evaluate it, call you and let you know what we have found out. At this point, we normally take a credit card payment and proceed with the work.

Your cylinder is first bead blasted to clean it to make it look new again. We do not remove factory paint on the outside, but we can at your request, for an extra charge.

The cylinder is then bored from the base side down as this is the most accurate way to be true to the crank, obtaining the proper RA finish to the manufacturer’s requirement.

Then we hone it to match the piston size. This is blueprinting the piston to the bore size.

After honing all cylinder edges are chamfered, this includes all port edges on 2 stroke cylinders, as this aids in ring wear and ease of assembly.

Your cylinder is then rinsed in parts washer, washed in soap and water, then lubed so it won’t rust, and bagged and boxed for assembly.
