whilst i wait for a gasket for the mighty thou i thought i would take a look at the replacement engine for the 600,wired the starter motor up to a battery and it turns over well with good compression, going to sit the new engine on the floor next to the bike, extend all wiring from bike to new engine and use the bikes ecu etc to start the replacement engine, sounds good 
...got an old wiring loom in the shed,stripped it and took coil and tps wiring and fitted to new engine,generator wiring was different so loom must be from a 2000> bike, will fit gen from bike to new engine,wiring looks long enough without having to extend it,got a remote fuel tank and a spare battery which i will connect with jump leads,probably will need a earth lead linking both engines...
not my favourite subject wiring/sparks but i`ll give it a go...and who knows i might learn something :lol
