I like the use of the magnetic gauge pins.
Some interesting discussion in some of the replies :

rollies replaced primary seals a couple years ago not sure if main crank seal was done ,i replaced that seal 3000 km ago, looking at the old sleeve/race the marks where the seal sat they look even not sure if the seal is oe just stabbing in dark,

found the problem, put dye in engine went for a 85km ride after couple days didn't think gone far enough but checked anyway dye in all three compartments ,checked crank runout at compensator outer edge .016 thou (.4mm) checked  lock nut washer the same, marked the spots runout in the same spot.i know some will say check at crank but to far out to go any further if it was close id go further. I believe this all stems from head on  accident 11000 km ago complete front end replacement, have reopened insurance claim waiting for assor to visit

well insurance says wear and tear looks like I'm going to rebuild the old girl i have a pinion shaft runout tool on the way ill check properly to see how much the shaft is actually out and decide weather to replace or repair flywheel assembly , seems the only ones available are s&s looking at 3 grand i cannot find a cheaper brand than that,why cheaper you say 1 budget tight ,2 im not a boy racer give it a bit of stick occasionally and do mostly touring im 69 done 85000 km so i think ill be doing well to do another 85000 on her  ,anyone out here got a take out flywheel sitting around let me know,surely there was a lot of upgrades from when these bikes were new if anyone interested ill keep you posted

I've seen take out engines for sale for less than the S&S crank, obviously they are an unknown. 

i know someone who used to do flywheel straitening in their workshop and still has the gear we are going to have a crack at it and see how it turns out
