I recently purchased a 2004 r1150rt-p with 48,000 miles. The man I bought from got it from the WSP online auction about a year ago. He knew nothing about BMWs and thought the bike was in perfect condition. It was not, but I did not think there was anything seriously wrong and the price was right so I purchased it. My friend and I (he's an A&P and has 3 BMWS) did fluids , brakes, and valves also did throttle body sync put on new steel quick connects and changed plugs. The difference is amazing. I have 2 issues. One is popping on deceleration and the other is a top speed of 109 mph. I have checked the speed on two occasions and in both 5th and 6th gear. Top speed is always 109. Any help would be appreciated.
