Hi, folks! Long time no type. The important part starts a few paragraphs down, after you see "trouble" written in bold red. So I just bit the slowest bullet in history, and I'm glad I did! Bought myself a Bee-Em-Double-You! Dream come true. My first "new" bike, after years spent on Muraveys, Jawas, Dneprs, a Moto Guzzi and other such creatures. I said "slowest" because I met a lovely German couple who were touring around Europe for the nth time on their BMWs - this was two years ago. The gentleman rode an R1200R. The lady pulled up on a gray 1995 R100RT Classic. Had only seen the latter in pictures (we don't have them in this part of Europe) and had dreamed about one for years already. I took it as more than a mere coincidence that one just happened to pull up in front of the shop I worked at. The lady got off the saddle, walked in and asked politely if I could help with a flat rear tyre. They had caught a nail some couple hundred kilometers back. The luckiest nail in my life! Here's a shot from their photo album, the day we first met: And help them I did. They let me keep the bike for a whole day and I was hooked! Long story short, I promised I'd save up money and buy the thing from them once I'd be able to. Check us out (boy, was I chubby!): Fast-forward two years later to our time: the gentleman sadly lost the fight with cancer, the lady almost ran out of patience after the initial 3 month deadline and I barely scrounged up the cash. But scrounge it up I did. Went on the roadtrip of my life all the way to Northern Germany with my small trailer, homemade wheel chock and everything. There were even a few stops in between, which made for a lovely journey. But that's a story for another time. Still, it warrants a few photos: Will post more if you so desire. Got it home and registered it after a lot of hassle. Fixed some minor stuff, like some superglued air intakes in the fairing that were rolling around from vibration. Installed the plate. Went for a 50 km (35 mi) evening ride and I was in heaven. Best sound, best feeling, best ride ever! But now I'm in trouble, guys. I'm in trouble. The next day it died on me. Suddenly, on the open road, at about 40 mph / 60 kph. Total loss of power on both cylinders, with a loud backfire a few moments later, as I was coming down to a stop still in gear - all while trying every single roll-restart trick learned along the years on my old Commie-block bikes. Even boxers. I don't know BMW airheads, this is terra nova for me. But the trouble seems definitely electrical. First thought it's fuel starvation, but it never happens so clean or sudden, neither does it kill both carburetors at the exact same time. Pulled out the fuel lines - gasoline gushing out. Went back to electrical diagnosis. Bike could restart for a few sparks on both jugs, then it would die again. Could even restart it throttling up, but still only got a second's worth of engine activity, then complete cutoff again. Pulled out plug, grounded it against the cylinder head. Started the bike at idle on the remaining cylinder, saw the spark how it misfired every third or fourth cycle (mirroring the stuttering activity on the working side) - and, surely enough, it died again in an instant. Still got lights and everything. Checked fuses between seat and tank, nice and tight. Checked kill switch and bypassed it with a delicate screwdriver - no difference. Moved coil wires a bit under that barndoor fairing - same. Waited for it to cool off a bit and the restart got me about half a minute of engine works, then the circus came back around. I dread the notion that my coil's busted. Checks out with a multimeter at 0,5 ohms in the primary and slightly more than 12,8 kohms in the secondary. But it was a hot 90F / 32C day today. Trailered it to my folks' place, took the gas tank off, snapped a few pictures. Looked pretty clean, apart from the dust. Noticed old paste between the ignition module (is that what the Telefunken bit is?) and its heatsink. Also, the right-hand coil wire had a lot of play in the coil output (Bosch twin coil, "red plugs"), but can't tell if it's been like that before or if it started after I pulled it out by the side of the road. Fixed it temporarily, started the bike (cold this time). Idled and revved fine for about a minute; you can see the rest in the video below. Should mention it has more or less sat over the past two years, except for the occasional garage-5-min-start-and-idle routine. I know that long storage periods tend to "dry off" (for lack of a better term) electrics. Any leads on this? Thank you kindly!
