So far this has happened twice with about 3 weeks in between. First time a rider in a group ride wrecked. I killed my bike ran back to see if he was ok. Off the bike for about 5-10 mins and knew I had left my key on. Went back turned it off. About 2 hours later went to start it and no workey. Turned over a couple times and died.

Then last night got off my bike for about 10 minutes again. Went to start it and again turned over and it was dead. As far as trouble shooting. I checked the brights and revved up the motor. The lights did get brighter when doing so. Any ideas? Every other time it starts just fine. Don't really have any issues while riding either. BTW it's a 01 929RR.

 

strangely enough, this sounds like a problem with the fuel pump/injectors for my truck. that just stumbles pretty bad on a hot re-start. these bikes have sensitive regulator/rectifiers and stators. check the manual for testing these first. since the problem is intermittent, it's pretty hard to diagnose. sorry dude, i hope someone has more for you.

 

check your battery, negative terminals can corrode and ya need to shave the corrison off them to get good electrical flow. if it runs one day and next day its dead thats why. happened to mine last friday. just shave it off with a pocket knife

might me time for new plugs also, i bet they are stock too.
