When is cylinder honing required?<br />Replaced cylinder head on Yamaha TDR 125 (second hand part). When the bike is driven, power fails. New rings were fitted. Thanks, Dan

What is the compression on your scoot?
Honing is for small imperfections.If you can run your finger nail over Imperfection and it clicks or hangs up you need a BORE job..Honing is for very small issues. Seconhand parts also must be inspected and checked for wear.Mic the cylinder for proper specs. Please get back at me and Ill try to be of further service.
