Hi guys thanks for the replies so far. Well I had the battery off last night to recharge it as I pretty much drained it when I broke down. Slapped it back on this morning, and oh-my-god. The thing nearly caugh fire on me. No idea what the hell happened. It started with me trying to fire it up but no joy, wouldnt even turn. Just sum wine and ticking from the battery area. So I though maybe I didnt make the contact good enough so I tightened it up and still no joy, but only this time smoke start coming from the battery area. It kept coming even after the ignition was off, so it was a scramble to get the thing disconnected.
I suspect when I pressed the ignition, for some reason the starter motor wouldn't turn causing the motor to draw too much current so the relay fused shut and kept the connection even with the ignition off.
After the smoke cleared it looks like no damage was done to the bike, all the heat was in the battery, so it's a new battery now and probably major electric issue due to this short. Hopefully the relay is easy to replace and the starter motor isn't totally fucked.
In terms of history, the bike had a major service 3000miles ago, with the ABS removed. No electrical work was carried out, apart from checking it was ok. I don't have the full details with me, but it included things like new fork seals, plugs, brake hose's, pads, oils and tyres.
What vex's me is I did 130 miles no worries, then the next day all Pete tong. Somone else suggested perhaps the injectors were stuck open?
Either way I gonna need a good parts place, apart from eBay where's good for cheap k100 bits?
