hi fazerider..............................thats a bummer but got home in the end :rolleyes .....might be worth checking those connections again after going over that bump    let us know how you get on 

Thanks, Red.
For months I'd thought there was an occasional misfire when the bike hit bumps, that was part of the reason I'd gone over the connections a few weeks ago. Balancing the carbs at the same time made the bike so much smoother I thought that had cleared the problem. It's definitely electrical, but I'm pretty sure the cause is elsewhere... and I spent a fair time checking nothing had come loose under the streetlights last night before admitting defeat and calling for rescue.

Tried to kill some time while waiting for the van to arrive by taking some arty-farty pics, but only managed two snaps before the battery in the camera died. :lol
