For sale is a pair of OEM cylinders that have been professionally bored, chamfered and finished honed to match the new ProX pistons so the kit is ready to install. Wrist pin bearings and top end gasket set (as shown) are also included in the kit. Cylinders are included in the listing price but I will offer a $200 each or $400/pair core refund if you return useable cores.

If you would prefer, you can send your cores to have refurbished and I can also use a different brand of piston if you send your cylinders. Please see my other listings or ask if you don’t find what you are looking for

Please note: I try to take good pictures that reflect the actual condition of the part! Please look at the pictures closely as I do not accept returns! Parts may contain normal wear from use but are in good useable shape with no visible damage unless specified above. Being that these parts are use they are being sold as is. What you see is the actual part or parts you will get. I often have other parts that are not listed so please feel free to ask if I have them.

Full payment is required no more than 7 days after purchase! No exceptions! All items are available for sale locally so I reserve the right to end items early. Items typically ship quickly but I do occasionally travel for work so it may take up to 5 business days to ship.

Due to the nature of the power sports component and necessity of proper installation I recommend having a professional perform the installation and I cannot warranty any components once installed. If your engine had a failure before and that is the reason for purchasing this you need to find the root cause or there is a high likelihood it will happen again. By installing the components you consent that all dimensions and part conditions are acceptable. For all engine components please be sure to put startup lubrication on the necessary items to prevent dry startup. Cylinders are typically are shipped with a protective oil on the bores that will need to be wiped off with a lint free rag prior to assembly.

If you live outside the contiguous 48 states, please contact me before purchasing as I primarily ship UPS ground. Shipping outside of the contiguous/continental 48 states often incurs additional/excessive shipping charges which will be the responsibility of the buyer unless all of the items can be fit into a single large USPS flat rate shipping box. Returns are subject to a 10% restocking fee to cover labor and shipping.

Measuring tools and bore bar pictures are not for sale but rather for reference of the boring process.
