Ok...need a little help here please. Hopefully you more experienced wrench-turners can provide some pointers. At the risk of sounding really dumb I am going to ask your advice with some issues I am having today with my '91 R100 Monolever/Classic. The bike has run perfectly since I bought it earlier this year. It has always been properly taken care of and all the maintenance is up to date. A complete service was done by a BMW shop in March. I rode it for more than 2,000 trouble-free miles in the past month.
Earlier today I washed the bike thoroughly and air dried it with the blower part of my shop-vac. When I went to crank it up so I could ride for a little while, all the lights came on and it would crank normally but would not start. I checked the fuel level and all the other normal things, tried to start it again but nothing other than the engine/starter just turning over. I then pulled each plug and while cranking touched the cylinder to verify I was getting spark....check. Towards the end of my spark check I got a loud BANG that surprised me....a backfire.
Frustrated (and worried I was going to screw something up) I pushed the bike back in the garage, and since I wasn't going to ride, I poured a beer. A little while later (20 minutes) I turned the key and the neutral light would now not come on....only the red GEN light. The key was on and I was not trying to crank the bike and about 10 seconds later the bike backfired again.
I fear I got water in somewhere I didn't want it to be. I removed the gas tank and will let it sit overnight.
Any suggestions on what to check tomorrow?
Thanks in advance for any advice.
All the best,
Brian
