Hey everybody I have a 98 yz250 project I’m working on. When I got the powervales out of the cylinder I noticed there was some scoring on one side. Are the power valves damaged beyond use or are they ok to run after I clean them up?



Thanks for any help.

Looks okay to me, if you're worried about the grooves take the dremel to it to flatten it out and clean up with some fine grit wet and dry.

Another little tip with powervavles is to leave them to soak in full fat Coca Cola. It will eat through all the baked on carbon, and is a little trick learned from cleaning the gas plugs from the machine guns in my former life.
