advice needed: valve shim time

[Jim Hyman]

Robb, Mark's advice is right on the money. Kawi specs are intake 0.004 to 0.008 inches [0.10 - 0.20 mm] exhaust 0.006 to 0.010 inches [0.15 - 0.25 mm] In theory, replacement shims change the clearance by 0.002". I'm a fan of loose clearances and suggest doing all valves so that your new settings will be: Left Intake .007/in Right Intake .007 Left Exhaust .009 Right Exhaust .010 KLR valve clearance tightens up over time. My KLR pulls stronger at low to mid throttle & runs much smoother with looser settings. I seldom run at high rpm & can only do 85 - 95 mph (indicated) with a full load of camping gear.

I don't want to stir up any big debate over shims.
