Hello, Quick question about valve clearance on my newly purchased '00 XRR. The previous owner uncorked it and put an XR's only competition exhaust on it but kept the stock header. As I was going over the basic maintenance on the bike I noticed the exhaust valves were way out of spec. This is my first bike with auto decompression, so I'm wondering if that has anything to do with it, or if uncorking/changing the exhaust caused the previous owner to alter the exhaust valves but not the intake???? or maybe its indicative of an engine problem that might require looking into. According to the manual I got, the intake should be set at 0.006 ±0.001 inches, and the exhaust should be at 0.008 ±0.001 inches. My intakes were set at a reasonable 0.005, but both exhaust valves were at 0.015, nearly double where they should be! In my limited experience, valves usually tighten up with use, not loosen up. I'm hoping somebody could shed some light on why they might be set so high. I took multiple measurements multiple times to ensure I was TDC on compression stroke, and tried my best not to let the flywheel rotate backwards. I'm planning on setting the valves to within spec, but thought I would ask in case there is some bike specific reason why they are so far out. Thanks guys, Mike P.S. sorry if I posted in the wrong spot!
