Even if you wire it backwards! Yesterday, I did a very vigorous run on my newly velocity-stacked Commando, in which I bounced it off the 7000 RPM rev limiter many times. When I got back home I noticed that the finned exhaust nut safety wires had big loops in them. WTF, I thought, that's impossible. Well, of course it's not impossible if you somehow managed to wire the nuts "backwards!" I have no idea how I did that - I safety wire things regularly but, of course, I immediately rechecked all the other safety wire! The good side is that even though the exhaust nuts were wired backwards, they still can't totally unscrew! Furthest they could go was less than 1/4 turn until the wire tightens up in the unscrewing direction. NOTE: I have the original Norton 7000 RPM rev limiter; when I see the tach hit 7000 RPM, I shift gears. Still not sure how I wired those nuts incorrectly but just goes to show you that even if you feel very confident that you know what you are doing, it is still possible to get occasional proof to the contrary.
