Been riding Harleys fo 30 years, and just picked up my first BMW. 1994 R1100RS with 17k miles and full service records. I bought this in time to make the rally in Great Falls. Had new tires installed and the 18k mile service done before the trip. Everything went great! 1700 miles no problems. Then last week, the bike started hard. Then ran rough all the way home. It won't rev above 4k rpm. Checked fuse 6 and swapped the relay, all ok. When turning on the ignition, I can hear the pump pulse, and fuel returning to the tank. But when the engine starts, I can't hear the pump running in the tank. With the engine running, should the pump run continuously? Like I said, everything was fine since June until last Friday. It has only had non ethanol gas since new. I love this bike, but could use some help. Could it just be a fuel filter?
