The bill for my engine rebuild will be £850-900 ish. That includes new alpha big end, main bearings, rebore, new
piston and rings, valves and springs etc, plus cams and larger inlet valve. I'd hoped it would be around £750:00 but I suppose the cam
and inlet valve modification are worth the extra. I see no point in doing so much work on the
engine, knowing that the head needed sorting out, and not completing the job
properly for the sake of £150:00.
At least the bike will be up to spec apart from the front forks and indicators. We can then fit the indicators and put some oil in the forks and see if any oil leaks and, depending on how fast any leak might be, that will help me decide whether to just keep topping the forks up, or consider having the forks repaired!

Pushrod woe
As usual, click any image to zoom in.
I've taken the inspection cover off and you can see the exhaust push-rod seated tightly under the exhaust rocker arm (at the 3 o'clock position).
At the 10 o'clock position the inlet valve's rocker arm has been separated from its push-rod which is now wedged firmly behind the rocker arm's downward facing semicircular nipple.

This
means the inlet valve is jammed open probably resulting in a bent valve stem.
Hope there hasn't been any more damage done.
