I got a 2002 R1100S a couple weeks ago and it ran fine. Tuesday I rode it to work and when I got on it to go home I saw the low fuel light. I stopped and filled up. On my 35 mile ride home it started surging and wouldn't rev all the way to redline. It made a "bogging sound" when opening the throttle all the way. The idle dropped from the usuall 1100 to 900 and by the time I got home I needed to keep pumping the throttle to make it up my street at 5MPH. I assumed I got bad gas and picked up a new filter the next day. After draining the tank and running the fuel through a paint filter it revealed NO DEBRIS. Inspection of a sample in a clear glass jar SHOWED NO WATER OR DEBRIS. I refilled with NEW FRESH GAS from another station and it's no better. It was poppin' through the airbox and generally running like crap. Here's what we have done so far
1. Drain fuel install new filter with fresh gas...No Change
2. Swap Coils.... No Change
3. Check Fuel PSI... It's 25PSI @ idle dropping to 21PSI when reving engine. I think this is too low?
4. Cleaned HALL SENSOR's.... It actually is alot better now, But still not right.
Any other ideas? NEED TO GET IT FIXED ASAP! Got a ride next weekend and local BMW dealer can't even look at it for 2 weeks.
