I would do the clutch adjustment. i also had a problem last night, but mind was at the other end, I was going ~70, tach shows 3K, wanted to pass some slower traffic, turn the throttle on, tach goes from 3 to 4 to 5+, but I'm still going 70, wtf. The clutch can't be slipping with only 2500 on the bike. Stopped by the stealership and asked if the clutch adjustment was part of the 1k service, they had no clue. Went home, and the clutch adjustment should have been done per the manual. So i just did the adjustment per the service manual, what a difference, the bike never pulled that hard before. Last week I put the bike on a dyno at a local event ($75) just to see where i was at with FM stage1 setup, was a little dissapointed at the hp number (78 hp, but torque was 96ft-lb). Now i believe that the low numbers was because of the clutch slippage. All is well now.
