Electrical cut-out R1100RS tipped to left


First I would like to thank all of the regulars on this list who have  
been so helpful. A couple of years ago I had stretched head studs on  
the right cylinder that was causing an oil weep and you all helped me  
sort it (new studs and the correct torquing procedure). Although I  
don't contribute much, I appreciate the dialog and I've learned a  
lot. So here I am with hat in hand again. I think this could be  

Here's my new challenge. When my 1999 R1100RS (32K miles) is tipped  
even a few degrees (less than 10) to the left, the electrics cut out  
completely. Tip it up straight and the electric's come back on -  
lights, idiot lights, ABS flashing correctly etc. - although the  
engine shuts off. I thought it might be a fuel problem but my test  
case is: key in "on" position, no ignition. Tip to the left -  
everything goes dark, tip it upright, everything comes back on. I  
touch nothing in the meantime. It's not intermittent - does it every  

Background: Last fall I smelled a hot electrical odor. The the engine  
ran erratically - and got worse the warmer the engine got. Because of  
the intermittent but severe nature of the "cut-out-rough-running- 
stutter", then normal running for a minute or two, then repeat, in a  
very erratic pattern, I suspected the crank-position sensor (Hall- 
effect sensor?), but I have no diagnostic tools, so this time sent it  
to the dealer. They confirmed the sensor was burned and some wires  
melted. They replaced the sensor and the wiring.  I also remember,  
one of the symptoms before the sensors were replaced was the bike  
often cut out briefly tipping into a left-hander. Not pleasant.  I  
had them synch the throttle bodies also. The bike got back so late in  
the winter I never had a chance to test it on the road.

I just put on dual horns and steel brake lines, a new Optima battery,  
and ran it through the pre-season check, let it idle on the center  
stand. it sounded really sweet. As soon as I pushed off it died. It  
took me a while to to figure out that it was going to die every time  
it was tipped slightly to the left.
