      Do I need to rebore my head I have a noise coming from my bike sounds like a knock from the piston I'm gona strip it down and order a piston to fit the current bore my question is is there anything I need to check will I need to rebore if the cylinder looks OK or is it literaly a case of ordering the correct size piston and popping it in

        A specialist will tell you if you need a rebore.

        I would at minimum get it honed. Don't need to touch the head. Depending on clearances, may need to modify the powervalve.

        Always Originate, Never Pirate!

          @ward4014 take it to your bike shop have them measure it and buy a piston while you are there
