Thanks for the tip Colin. First thing I did when the old girl died was pop the fuel cap to check the fuel level. I took your advice & tonight I checked the vent line to find it OK. Failing any other helpful advice from some very experienced BA members, I've just arranged to get some Magnacore HT leads made up tomorrow with some very waterproof caps. Prior to my return to motorcycling, I was heavily involved in competition 4WDing and Magnacore custom HT leads were the ducks guts for keeping your petrol engine running while giving it a decent dunking in rivers & creeks. I'm hoping I'll have the same success with these leads on my TBA. The reason I'm fairly confident the problem was spark related is that when I did manage to get the old girl running, she ran on just one cylinder for about 30 seconds before settling down as a happy twin again. I would nearly bet my left gonad it was the r/h cylinder that died due to the tremendous amount of road spray coming off a series of B-Double semi's.
