My 650 has 46,000 miles on it. I just changed oil in the engine, transmission and final gear oil. I used Shell T6 Synthetic for the engine and transmission. I initially overfilled the transmission then remembered the oil level bolt, removed it and let the overfill out. After driving this a couple of days, yesterday, I noticed a couple of what seemed to to be slippages on a 30 mile trip to work. On my way home no slippages noted. Today on my way in, the slippages were much worse - I had about 6 of them and the bike stalled a couple of times with the red oil indicator light coming on. I drove it home and parked it. Any advise on what is wrong and how I can diagnose or fix or this a dealer item? Thanks!
