Hello Alex, those studs are 5/16” UNF, most of the 5/16 bolts on your bike should be that thread, but goodness knows this far down the line!What a day. I'd be far more despondent if you weren't here, offering advice and encouragement
Mick, great idea! The long but fits. Tried every bolt I took off bike, none fit. Do you know the spec of these two central bolts?
Peg; thanks for the detailed reply. ATF leaks out of the exhaust ports, so pressure won't work
The pistons are a long way down. I ripped in 750cc of ATF/acetone. Sticking a screwdriver in, from top of plug thread to back of piston is about 13cm.
I've cut up two curtain poles, done as you suggested. So far not budged, but can relax knowing there constant pressure applied.
I'll try splitting crankcases in a couple of weeks if no joy. Almost embarrassing to say, so far can't get cylinder barrel higher than about 8mm at back,4mm at front. Problem for another day
