I know. Having the dealer perform a Valve Clearance check/adjustment ain't cheap. AND....most have reported that when done, all valves were within spec. So......many have decided to blow this particular maintenance evolution off.
I recommend you have it done. There is always the exception.............
On my first two valve checks, the dealer replaced one shim each time. In both cases, the valves with the shims replaced were within spec, but on the very edge of spec. And I know that when forum member vectervp1 took his 05 FJR to the same dealer I use for his first valvle clearance check at Thirty-something-thousand miles (several thousand over the recommended interval), had had several valves that were tight, and out of spec, and needed to be shimmed.
BTW, this is the best wrench I have ever had. He does stuff RIGHT. Period.
Well, I recently took my FJR in for it's fifth valve clearance check with 140,400 miles on the clock.
The results?
5 valves out of spec on the tight side, and one on the very edge of spec. The specifics:
Exhaust. In spec range is 7-10 thousandths (rounding)
Actual measured per cylinder:
1 - 6 8
2 - 9 8
3 - 8 7
4 - 9 5
Intake. In spec, 6-9 thousandths.
Actual:
1 - 6 5
2 - 5 6
3 - 6 5
4 - 6 7
So six of the valves were re-shimmed back into spec.
Now perhaps this is because I have a high mileage motor that they are getting out of spec. But is it worth the risk to your own motor to not know?
What value do you place on peace of mind?
I is just sayin...............
