Many apologies for the delay in posting - my feet haven't touched since Christmas.
Anyway, just to let you know what happened, I finally swallowed my pride and gave it to my friendly local mechanic, who, after much poking and prodding (and calling in a mate of his who's an auto electrician), found the problem was a short on the ignition barrel. It wasn't blowing because the bike was revving, it was blowing because the bars were moving and causing the dodgy wire to short. Must admit, I wouldn't have looked there in a million years. At any rate, it's all hunky dory now, just in time for lots of snow and ice. Ah well. On the positive side, only 23 days until Spring!
Many thanks for all your help, and hope to catch some of you on a ride out when the weather's less brass monkeys.
