And there's more...
Got the selector mechanism assembled and checked all the gears appear to work...
Prepared to put the barrels on... that was a bit stressful but I think I managed to do it without breaking any rings. Those oil rings are a bugger though - once they're on the piston, each end does like to tucking under each other rather than butting up.
I used Laser piston ring compressors, which worked pretty well - the biggest issue was keeping the pistons level. I was using bits of wood, but a proper tool would have made life much easier. Hey ho. Engine seems to turn over smoothly though - and of course it's pretty snug because it's had a rebore.
Then I lapped the valves in and refitted them with new valve stem seals. Head ready to go on soon!
I've put the engine as it is so far in the frame, as it's easier to lift the frame over the motor when you only have your wife to help and with lockdown you can't really get someone strong round to help...
I've since added the timing advancer, the oil breather and oil pressure switch. I've been farting around with engine mounting brackets cobbled together as these were missing when I got the bike. The ones in the photo are some second hand chromed ones I got, but the chrome it flaking off. I also had another set which were normal black paint and rust, so I've rubbed them down and resprayed them. Soon to be reassembled with new bolts and spacers.
