About nearly two years ago my '94'k1100 got power issues. I eventually found out that the intake tubes were not in the best shape. Just replaced these. Now in fairness the bike has not been that active for the last two years although i regularly turned on the engine. I replaced the spark plugs. It isn't running smoothly though. At idle the engine seems fine. But when i take it on the roads it loses power at about 2000 rpm and as i apply more throttle the rpm or speed will not increase then suddenly it will get a boost of power and accelerate in rpm and speed. At idle after one or two miles of this behaviour the idle might experience the same behaviour.
