I was riding yesterday at the track and everything seemed fine till the last ride. I got on the track and the bike was making a weird noise and bucking back and forth. I pulled off thinking the rear axle might be loose. As I slowed, the clutch started to grab and pulsate. I was able to ride it around starting and stopping to try and figure out what was going on. The clutch was grabbing. Today I drained the oil and found metal on the drain plug magnet. Little bits and pieces. After the oil drained I put the drain plug back in and pulled it out to find a little more metal bits. No metal was found on the oil filter. I poured about 500cc of oil in to flush it and drained it again. No metal this time. I then put the used oil filter back in and filled it with oil. I started it and then put it in gear to run it on the center stand. When pulling in the clutch the rear wheel would still spin. Hitting the rear brake pedal to stop the wheel with the clutch in and releasing the brake the wheel would spin. The metal isn't clutch material. Maybe something with the clutch basket. I don't know. I guess I'll have to pull the clutch out to explore more. All this after 30 hours on the bike. Any ideas?
