SANTA Posted January 22, 2013 Share Posted January 22, 2013 background r1100s with motronic 2.4, twin spark with 48000km as far as i know the TPS and the idle stop screw on the left side have never been moved. over time as miles have piled on it would require more and more RH BBS to get an even balance at idle. and the high speed syn was funny, it would change from left to right, it would not hold steady. i came to the belief that one of the idle stops screws had somehow moved, the only solution to set the both BBS screws to 1.25 turns out and then use the right idle stop to achieve manometer balance. i have done that and it runs very well now, with only ONE ISSUE; when the throttle is rolled on to accelerate, one can feel just the slightest left/ right imbalance initially, almost like a single cylinder engine accel, don't know were to start to correct this. suggestion are requested, Oh and its -30deg outside right now, the garage is a freezer, so nothing is going to happen for a while but i want to make this go away thanks Link to comment
