being as it was a nice day, I thought I'd haul the bike out of the shed and see if it still runs... kicked the kickstart quite a bit, and also tried pushing it down the yard, to little effect (yard's dead flat) so I thought sod this. dug around in the shed and found the electric starter, fitted same, dug around some more and found the switch, went and looked up which wires to connect where, connected it all up. dead as a dodo. hmmm. looked more at the wiring diagram. aha. starter relay. found that and looked at it, after a bit noticed that the trigger wire was on the wrong terminal, which of course with the switch missing made no difference. put it on the right terminal and it worked. bike turning over, battery mostly flat. fetched spare tractor battery and jump leads. Now *thats* what I call turning over... after a few seconds, it fired up on the right pot, and after a bit more, the left one decided to play as well. Ran it for a bit, shut off, put all miscellaneous bits back on and now it'll (just) fire off its own battery. will give it some exercise this afternoon.
