Took off the frame to get to my rear cyl head for removal. Broke a tap... FML

- Does the engine need to be at TDC before I remove the head?
- If it does, how do I put the bike in gear without using the clutch lever?

If you had your frame off, what is all of the work/maintenance you would do to your motor?

I'm picking up a used XB9R to ride while my XB12Scg is down... I'm willing to take my time.

I don't want to do a full rebuild, but if I'm taking off the rear cyl. head, what else should I do?

Thanks in advance.
