This listing is for cylinder boring service that I provide to you on your single cylinder Honda motorcycle. Here is how it works: You provide your cylinder and a new oversize piston, (OEM or aftermarket) and I will bore and hone your cylinder to factory clearance for that piston using modern boring and honing equipment. You get your own cylinder back ready to install and run. Shipping back to you is free too, even Alaska and Hawaii. I have been rebuilding Honda motorcycle engines since 1977. Let my years of experience work for you. Check out my other auction services/store/feedback and buy with confidence. After you hit the BuyitNow button I will send you the address to ship your cylinder and new piston to. Thanks for looking!
