I fixed it!....sort of I replaced the LHS engine cover, broke the basket getting it off (lucky I bought one in anticipation), filled it back with oil, and it didn't leak. Hurrah. The bike still wouldn't turn over, I managed to bump it, so the electrics seemed OK, I figured a broken starter motor, the sidestand switch or some other connection disconnected. Turns out it was the clutch lever switch that was knackered (should've noticed before, as the bike landed on its left hand side, and the little ball on the end of the lever was grazed), I got it to turn over and run beautifully when I bypassed the switch, just used a bit of wire to connect the terminals in the plug and voila. Only problem with this is the sidestand cutoff switch doesn't work when it's down anymore, but at least I can get to work now! Just need to find myself a clutch switch, and im set. That and repairing the cracked fairing =/
