Valve clearances - out of spec
« on: 19 March 2017, 11:44:50 am »
Well I guess Im one of the unlucky ones.....


This job started as a simple AIS removal and, typically, has progressed to a much bigger job. The classic - "I might as well just do so-and-so while I'm at it." Anyway, decided to check the valve clearances while I had the front end stripped. The bike has just about covered 26k miles so is due for a check anyway.


All except one is within spec (see picture). Question is.... is it that critical?


I haven't yet looked up how big a job it is to re-shim the offending valve. My instinct is just to get on and do the job properly while it's stripped down. But what are the consequences of just leaving it?


To be honest, I rather expected that any out-of-spec readings would more likely be over-tight valves rather than loose ones. But perhaps that's just exposing my ignorance of the engineering...


The other question is .... is it worth re-shimming any of the others that are close to spec while Im at it, or just the one that needs it?


Cheers foccers.

Now I'm really confused. Is 0.27 out of spec or not?

So I guess I should have searched the forum before posting this.  :o

So what was the answer?

I may be attempting to do mine in the near future.

The answer is in the FAQ sticky - the very first post in this section under the heading of "valve clearances". Pretty obvious really but anyone can make mistakes in the stress of the moment....
