2003 XR650R, 150 miles When checking Valve clearance the Honda manual (pg 3-8) has you roll the fly wheel CCW 2-3 turns to align the "T" mark with the index notch. And then make sure you are at TDC on compression. (decompressor has free play) When I roll the engine CCW 2-3 turns I observe the intake valves open with the piston lowering in the cylinder(intake stroke). Intake valves close(exhausts are already closed), piston starts coming up in the cylinder (compression stroke) "T" mark lines up, but piston doesnt reach TDC for about another 1/8 inch of stroke. At this point the intake and exhust valves are on the flat part of the cam so the valve clearance is not impacted, but whats up with the manual requiring the "T" to be lined up with the index and the piston at TDC on compression(my engine does not line up). Also while adjusting the valve clearance the intakes were right on .006 with a slight drag on the feeler gauge. The exhausts were a little tight I could get a .008 gauge in but it was real tight so I lossened the exhausts up. Now I have some tappet noise. I would rather have some tappet noise rather than tight valves. Part of the exhaust clearance problem was probably the straight feeler gauge I was using. It is hard to get at the exhausts because of where they are located. I have ordered some bent tip Motion .006 and .008 feelers. The exhausts should tighten up some with time right? Comments?
