Update;
painter phoned today, he's just finishing off the base paint and ordering the vinyl today.
I picked up the machining job yesterday from MSC (or western rebores) in manchester. top bloke,ex bike racer and checks clearances for you too.
so he puts in a head stud after i snapped mine trying to get it off, swapped over the liners to the ones that match the pistons,honed and skimmed them, then checked all my valves (one was bent)
Took the best valves from the spares motor, then recut the valve head and valves.
Then he skimmed the head all for £200.
love the machine oil smell too
here's the skimmed barrel
and the head work
