My bike had been sounding kind of ill for a month or two - it sounded like a tractor up to about 4-5k RPM, and there was increasingly a sort of clattering noise at low RPMs. A few days ago, it finally died in the RNP. It had been down on power a bit that day and the engine even noisier than ever, but when I hit 18k on the last straight before the ride down to weir, it all went to shit. I suddenly lost all power, it wouldn't rev over 6k (I guess that means I lost one or more of hte cylinders?), and the motor/clattering suddenly became deafeningly noisy. I limped it out of the park (so glad I got it back up the hill to the entrance), but it kept stalling and I couldn't restart it at the lights. The thing that made me curious is that I noticed that, even in neutral, when I rolled it back and forth there was a loud clacking noise. I could just be a complete noob, but I thought the engine was effectively disconnected from the wheels in neutral, so is it possible that I've either farked something other than the engine, or that I've farked the engine as well as something else?
