oh sorry, only rebuilt top end. I took the engine out before hand because i was expecting to need a full rebuild (even brought a new crank), turned out the front cylinder was seized, so replaced front cylinder, both heads and pistons, rings etc. Started bike up after everything is back together and ran nicely.

the spring hook thing at the engine end seems to work properly without the cable on. Have another engine to compare it too. I'll Play around some more and see what i can do.
