hi guys in new to this site and bmw motorbikes ,but i have a years of experiance of the oriental stuff.. my bike is a 1991 model k100rs 19v which has covered 29000 miles approx.ive been out a couple of times on my bike since i got it and ive had this fault both times,i was out a run yesterday and did about 20 miles when i rolled of the thottle coming into a 30mph limit and the bike lost power and backfired so i diped the clutch and freewheeld into a fuel station that just happend to be close by..started the bike up but she ran roughly and would not take the thottle,so i let her idle for a few minutes and the engine note changed and she ran smoothly again and woud throttle no problem.so i did the rest of my journey abot 60 miles without any more problems.the riding was varied from 60 mph to 95mph as roads were patchy in places:wet:.ive serviced the bike with new plugs set to correct gap,all new fillters and oil,i have also replaced the coils for gen new units and ive drained the tank as well ,there was very little crud at the bottom and the fine filter on the end of the pump was almost spotless.i have done a lot of head scratching over this,an intermitant fault like this seems almost impossible to diagnose,or i will have to let the fault develop,but i would rather solve this problem in case it does damage.any hints or tips would be much appreciated. .toecutter
