Ok guys I have the manual for my 750 and Im rebuilding the top part of the engine and Im at the point now where i need to time it. It tells me this:

Using a wrench on the alternator bolt, turn the crankshaft
clockwise until “T-R” mark [A] is aligned with the notch
[B] in the inspection window.

Where is this alternator bolt at and where is the inspection window?

Thanks
