Question for all of you- When you are re-shimming valves what clearances are you aiming for? Example- Tolerances are .20-.25mms. Current measured clearance is .18mm. Are you going to reshim for .23ish mm to be in the middle range of the tolerances? .25mm to allow for the valve to tighten after more wear? Or anything in between? Does it matter? I have my valves shimmed for the looser limits, but since then the bike has developed the famous valve "ticking" sound. Wondering if this is the cause and if I should reconsider my approach.
