Smaller shims? File them down?

Recommended Posts

I have a 2003 crf250r. It is like my friends 2002 crf250x, but it's the race version. Time for another valve job on my bike. I have the smallest shim in my bike and it needs to be smaller but they don't make any smaller. I just bought a full titanium washer set so I can use these as my shims. Can I file these down so they will fit better, and the will be the right size thickness. Thanks

Your valves are done its time for a valve replacement/seat recut valve shims are hardend steel titanium is softer you do not want titanium particals going around in your motor oil

This is a really bad idea!!!!

 

They're really hard treated steel and if you are able to cut into them, you won't be able to get them flat.

Seeing you know so much why don't you just take to the shims with an angle grinder, cut them in half, put them in and see how it goes.

Read your manual, this is not rocket science.

2002 crf250x does not exist.

When you say look fine have you taken them out?if your at the smallest shim they are done I bet they have a large step worn into them where they meet the valve seat.

REPLACE YOUR VALVES, VALVE SPRINGS, VALVE SEALS, AND HAVE THE VALVE SEATS RECUT BY A PROFESSIONAL. STOP RESHIMMING!!! UNLESS YOU ARE JUST TRYING TO DROP A VALVE.

Maybe he could just remove the shims and weld the top of the retainers shut?
