What happens when valve adjustment = out of shim range?

Recommended Posts

I just bought a bike with a bunch of engine work done to it and checked the valve clearances. I am down to a 1.25 shim on the right intake shim and am wondering what I need to do if it goes out of spec again when the shims only go down to 1.20? Would this require that I replace the valves? I'd rather not if possible since the valve work that has been done was pretty expensive.

That doesn't mean it will last forever. :cry:

unfortunately when they start going, reshimming is nothing more than a temporary fix. Pull the head off, if your familiar with 4-strokes do the work yourself, if not find a reputable shop and have them do it, or send it out to get it done.

If things arent too bad, all you may have to do is replace the springs on the intake side, lap the valves in, reshim and go. If the valve seats are damaged, then that will require some machine work and someone with the knowledge to fix it correctly.
