ok, when they do a valve job at the dealership, all they do is change your shims right?

A valve ADJUSTMENT is when they change the shims if needed.A valve JOB is removing the head,removing the valves and replacing or refacing the valves,seats,etc.

The intake valvles from the CRF will go right in and is a small upgrade,the exhaust valves are 1mm larger and will require CRF valve guides to be used.. I have done both and have had no problem with the vavles going out of adjutment!!!

The springs will work but you need exhaust retainers and keepers and seals ..
