Hey guys I'm having a real bad problem with my chain flailing wildly from side to side. It starts doing this from about 45 mph and up but somewhat intermittently. Throttle position seems to have an effect too. It makes the bike feel like one of my wheels is badly out of true. The vibration is causing my headlight shroud, instruments, and mirrors to jiggle side to side rapidly. This side to side play is causing the rear chain guide to wear very rapidly (down to the metal on one side). I put on a new chain and sprocket set about 2-3000 miles ago and this problem has just shown up within the last 500 miles or so and it's getting worse. I'm running 14/49 with a renthal sprocket on front and a steel JT on the back with a lower end RK chain with clip master link. The clip is on tight and installed correctly. I've tightened up the chain as much as I dare, about .5" play with the swingarm pivot, axle, and countershaft aligned. Anybody ever have this annoying problem before?
