Odd issue driveline
My K1200R has developed a disconcerting problem. 39500 miles. When accelerating HARD 1st or 2nd gear, possibly and probably all the other gears, the driveline will let loose for a split second. It feels as though the teeth on a sprocket have rounded off and the chain slips around the sprocket one tooth.. I know the bike has a driveshaft, I'm only describing how it feels. I've been doing a lot of searching online and can not find anyone that seems to have a similar issue. I've called 3 dealerships and none of them say they've ever heard of anything like this. My first thought is possibly the clutch, it works normally. Feels like it always has and does not slip at all under load. As long as I don't get on it more than about 75-80% torque, all is good. It feels very abrupt, no noise that I can hear, when it happens and it will let loose for a millisec then hookup normally for 1 or 2 full seconds then again it will let go for a millisec and then grab. I've only done it about ten times, I'm afraid of catastrophic failure! I would love to hear if anyone has some good theories before I do a search and repair. The engine is not misfiring and runs strong. Thanks for any time spent helping.
