Question about BMW K 100 RT Motorcycles
Ok. So, I have been using a battery regulator the past few weeks and hadn't had any issues with it. Although my battery is only a month old, I was told that I should use this to maintain it...Anyway, I unplugged this the other day and left for work. On the way there, my tach/speedo lights and headlights/turn signals began to flicker. On my way home, the lights did the same thing and eventually went out completely. I turned off the bike for a few minutes and when I went to start it, all I got was a buzz...I let it sit for 20 minutes or so and it fired up. Today it started up, and I rode a mile, turned it off for a few minutes, went to start it and buzzz...Let it sit for about an hour, and tried again...buzz...Since I was relatively close to my house, I had a buddy push me a bit and I was going to push/coast home. After moving fifty yards, I turned the key and 'boom', it started... I removed the battery, cleaned the contacts, had it tested...All are fine.... What do I do???
Check your grounds, check your alternator, check the diodes in the charging system

Hi, seems to be eletrical issue. Make sure if the battery works properly- check voltage. Weak battery can have correct voltage level when it is retiring, but when you e.g. push the starter, it quickly looses power.
If the battery is OK, it could also be a short circuit somewhere. You mentioned the carburetor cleaning- check if the heater unit cables on the carburetor are plugged correctly. Also, check fuse.
