[QUOTE="Trfsrfr, post: 206117, member: 3959"] Update: Haven't gotten a video yet that I can show, but I measured the valve clearances today; Spec : Intake .100 to .190 mm (.0039 to .0074 in.) Midpoint .145 mm / .0056 in. Exhaust .150 to .240 mm (.0059 to .0094 in.) Midpoint .195 mm / .0076 in. Actual : Intake (L) .004 (R) .009 in. Exhaust (L) .005 (R) .010 in. As you can see the left side intake is very close to the minimum tolerance, the right side intake is .002+ beyond the max tolerance. The left side exhaust is below the minimum tolerance, and the right side is exhaust is just beyond the max tolerance. Does anybody have any thoughts on these numbers? Would they cause excessive noise? Attached is a pic of the cam chain as it sits currently. Does it look weird, strange, or not right to anybody? It doesn't look right to me. It doesn't look like it's fully sitting on the cam gears. It makes me wonder if it has stretched, or if maybe it's a cheap Chinese after-market chain, or possibly the all-together wrong chain for the bike? It is noisy, and when I installed the tensioner I used a screwdriver to push the ratcheting thing in 1 notch more than it did under it's own spring power, just to tighten it up. I figured I would rather have a chain that was a bit to tight, than have it skip a tooth, which I have seen this thing do. Also - I tested the cooling fan; it pulls approx. 3.3 amps at around 13.7 volts. [/QUOTE]
