Valve Clearance

Intake 1 .003 2 .005 3 .005 4 .005
Exhaust 1 .005 2 .003 3 .006 4 .003
According to my manual it's supposed to be anywhere from .003 to .007. Can I ride another season or is it time to reshim?
I don't really understand that I need a thinner shim to increase clearance. I know the valve wears down in the seat and gets tighter. It seems to me a thicker shim would increase clearance, thinner would make the gap even smaller.

Should I reshim...or wait? I suppose I should get it taken care of sooner rather than later.

If the measurements are in thousandths of an inch, they are dead on perfect for a 750 twin. Not sure about a 750 four.Spectre1982 wrote: I just checked the valve clearance on my 82 Kz750 N1. They were as follows:
Intake 1 .003 2 .005 3 .005 4 .005
Exhaust 1 .005 2 .003 3 .006 4 .003
On my bike, the clearances moved very slowly when they did move at all.

Harbor Freight has a decent cheap torque wrench that does 200 Inch-pounds full range. I believe the spec on the cam cap bolts is 120 inch-pounds, probably better to go maybe 80 - 90 I-P. If you use a large range torque wrench that is not accurate at the lower range, the bolts strip VERY easily.650ed wrote: I probably would re-shim the tight ones before another season. Do one cam at a time rather than removing them both together; plug up the cam chain tunnel with rags so you don't drop anything down into the abyss; and be sure to use a torque wrench calibrated in INCH pounds to torque the cam caps to the proper torque setting. I would keep it to the light side of the torque range to be sure not to strip threads. Ed

Thanks for the warning on the cam bolts too.
