I just had my bike torn down so I could check the valve clearance. I attempted to follow the service manual in doing so, but ran into a few snags. First off, my rotor had two marks on it, and H and and I. When the I was lined up with the hatch mark in the case, the cam lobes were not opposite eachother, indicating TDC on the compression stroke according the service manual. The lobes were actually never truly opposite each other, and the E and I on the cam wheels were directly across from another. Am I just being dense, or is this normal? The bike runs fine, so I know the timing isn't as haywire as it seems like it should be. Any help would be appreciated.
