Don't do this!! If you really have to jump start, connect from car battery direct to m/c battery.CheersGarry
I'll second that.Jumping battery to battery should be OK.In fact some 1150 GSA’s and some later 1150 GS’s have external terminals for just such eventualities, and I’ve considered wiring something similar on the 80.However, if you want to start a bike from a car the other thing to remember is that an alternator on a car will chuck our enough current to fry bike electrics (HAMHIK), so make sure the car engine is OFF.
