I realize that this forum is dedicated to the trusty K100 and I have a 1984 one of those also. The problem I am having however is with my 1993 K1100LT. I took a leisurely early evening ride out to a local beauty spot two nights back and on my way home I hopped onto a dual carriageway road in order to get home for an appointment. Bike was running flawlessly at this point. I was getting harassed by an Audi driver so I decided to leave him well behind and hit the gas quite hard. All of a sudden I was missing a cylinder and running on only 3 - I managed to limp the bike home and park up for the evening. My first thought was that it was a failed spark plug, as I have not changed the plugs in nearly two years and I ordered some replacements from Motorworks. Today I got around to fitting the new plugs (the old ones were in a terrible state with hardly any central electrodes left at all and one at least seeming to have a light grey deposit almost crossing the plug gap, however they all showed signs of a good mixture and clean burn etc.) I did notice that upon tapping the spark plug caps that there was an awful lot of whiteish dust/powder that came out of them! When I had gapped the new plugs - NGK DCPR7E - and came to fit them, it did seem to me that, although the rubber boots seemed a good snug fit, the inner connection was not all that good at all. I wondered if all the dust that I had knocked out had perhaps been oxidised aluminium etc. and that the plug caps were not so good. Anyway, with all 4 new plugs in place and all HT leads reconnected correctly I hit the starter button. Damnation !! The bike is still only running on 3 of its' four cylinders ! Any suggestions as to the possible cause of my continuing problem would be warmly welcomed from the knowledgeable members here
