Correct spec for valve clearance 1854 cc V-Twin
You are going to need to purchase a feeler gauge that goes down to 0.0015, Grainger sells a single feeler gauge and a gauge set that goes down to 0.0015. You are likely not going to find a feeler gauge that is specced at 0.0016 and you are going to have a hard time finding a feeler gauge that goes below 0.0015.
Most feeler gauges will stop at 0.002 which is outside the spec for the valve clearance i.e. a touch too much clearance.
The Yamaha spec is virtually zero clearance at 0.0016 as it is.
If you are having a hard time finding a feeler gauge that goes down to 0.0016 check Grainer as they go down to 0.0015.
I ordered a feeler gauge set from Cucamonga Yamaha but it only goes down to 0.002 and it is for checking valve clearance on Yamahas. Don't order this feeler gauge set as it does not go low enough.
So I have now ordered the single feeler gauge that is 0.0015 and the feeler gauge set that includes the feeler gauge in it that goes down to 0.0015, I have not been able to find a feeler gauge that is below the 0.0015.
I have a hard time believing that valves could be noisy at 0.002 but the spec is below that for the maximum clearance.
