Great story Tumu ... I think it's a big deal when I do 500/600 mile day's in good weather. I don't know how you do it in rain, ice, snow and a bum foot. Thanks ....

This means that if you do a leakdown test on a KLR, it'll leak like all hell through the exhaust valve even at the peak of its compression stroke. You need to pull the valve cover off and manually wire the KACR disabled while you do the test. If you don't do this, the leakdown test is meaningless. ------------------------------------------- Good point, but I would argue that the KACR, if you look at how the mechanism works, requires rpm to be low (as you point out) but ALSO for the cam to be in a certain position for the small dowel to push on the valve shim to crack it open slightly. So as long as it's not in the 'wrong 30 degree range' - a very rough estimate at where it contacts - you're good for the test. It would seem that the recommended crank position to do the test anyway is TDC on the compression stroke - where the KACR isn't pushing on the valve shim. If you've ever done one a leakdown test before, you can't fight the crank rotation at anything else than BDC or TDC. Given the camshaft timing, valves are still in transition so this only leaves TDC on the compression stroke. So I don't think you need to wire the KACR in any position. This might save you some work.
