Hey all, My name is Kasey, im just looking for a little advise because im a little lost. 3 months ago i bought a 09' 1000RR from a guy about 2.5 hours away. the gauge says it has 3,300 Miles on it and this thing looked clean, no wear and tear anywhere. So i ride it around, decided to buy it, then ride it 2.5 hours back to my house, everything was fine. then i decide to ride it to work and while at lunch im sitting at a red light and the idle suddenly drops from 1500 ish, to around 1000 causing it to chug a little, and starts spitting white smoke out of the exhaust, and it smelled sweet, not like oil. when i would ride between lights it would be fine, but at idle it would do it again. The bike didn't run hot either, the fan came on at 220 and on the highway it ran about 180 degrees. so i get it in the garage and strip the plastics, tank, and air-box off. I notice the coolant level was low, the reservoir was empty. I run the compressions and they were 170/170/170/80, so number 4 was very low. then i did a leak down test and with 80 PSI in each cylinder they were 100%/100%/100%/60%. so once again cylinder 4 was leaking, and it acted like a head gasket with the smoke, and smell. but during the leak down i could hear #4 leaking into the throttle body,past the valves. at this point im not sure what to think, im well aware the motor is going to have to come out, but im not exactly sure what exactly could be the problem. any insight from the gurus out there would be appreciated.
