So, I own a 2007 Kawasaki VN900 Classic LT motorcycle, she's approaching 26,000 miles. I generally use it as a commuter when it's dry and/or warm, to work and back home. The only service I've done is replace the stator a couple of years ago when the original went belly up, tires when needed and the usual yearly oil and oil filter changes at the end of the riding season. The one thing I never gave any thought to was the valve clearance so I decided to check to see what the service manual says; they should be checked at the 600 mile interval, done; should be checked and adjustments made at the 15,000 mile interval - oops, never did that or any checks since the 600 mile check. So, I'm nearly done tearing her down to check the valve clearance. The great thing about this is if they need adjustment, simply remove the shims that are problematic and replace with the one that will put her back in spec. The service manual has an easy to follow chart to show you which one that's needed. Oh, I need to change the Air switching Valve, the one in there is rattling like the dickins. It's nothing that's going to hurt the motor if I don't change it, it's just the rattling is driving me up the wall. Roger
