Thanks for the kind words folks. Diesel can be so difficult to spot in the dry, easier in the wet. It was dry, but to be honest, I wasn't paying too much attention to the damp patch, because in my mind I was thinking it couldn't possibly be diesel as there was so much down. I'd sort of dismissed it as a wet patch, water or something.

Still, the bike's nearly fixed now (thanks to the boys at Phoenix), and at minimal cost. Having to fit the original pipe for now, until funds allow to get a fruity can again. To get myself back on the bike, I've had to get some kevlar jeans, because I can't get my swollen knee into leathers. Just hoping I haven't done any lasting damage to my knee (still bloody hurts)... >
