I've had a problem now for a couple of weeks that I just can't find the solution to. A few weeks ago, I finally had my CNW starter motor fitted to my MKI 850. What a fabulous product. However, about two weeks ago, the bike started to backfire and lose power until it stopped and wouldn't restart. Now, the bike starts easily, and then it runs well for 10 to 15 seconds and then starts backfiring on the right cylinder and then stops completely. I have changed the following to no avail. Same result. Plugs, plug wires, coil (single Accel coil) ignition unit (Trispark). I have stripped the carb (VM34 Mikuni) and checked fuel flow which was good. I have totally run out of ideas. I have two mates coming over tomorrow for a look. Charged the battery and while it is running, the Smiths gauges start doing slow revolutions, which is usually a sign of low voltage, as is the backfiring. However, the starter seems to have plenty of juice. Any ideas?
