Hi everyone, I am new to this forum and do not own the bike mentioned in the title yet. I would like everyone's opinion. The bike is a 2001 f4i, it starts and runs, however, it will not idle. As soon as you let off the throttle the bike dies. As long as you keep on the throttle, the bike will run. I am considering purchasing this bike from a friend for a very reasonable price. Has anyone had this problem before and if so what did it take to fix? I was a mechanic for a number of years and intend to fix the bike myself, if purchased. I am thinking it is a bad fuel pressure regulator combined with fowled plugs. The bike has 14,000 miles on it and I do not know if the valves have been adjusted. Any suggestions on what the culprit could be?
