Hi, I can't believe I couldn't find anything while searching for this, but I made the mistake of removing the camshafts before looking at the flywheel. Now, on my older Yamahas, the flywheel clearly had an "H" for whatever, and an "I" for TDC. This new one has three "I"s with what look like two scratches in between the first two ones (the ones that would make up the "H" in the old bikes). Is TDC the last line? The manual says crap all about this, only to align the "TDC mark" with the marks on the cover.
