It seems as if I'm having a more than one issue at once. The bike feels like a John Deere when shifting. Hard engagement of gears, beyond a little notchy. Also, it simultaneously started 'chugging' off the line in first gear, and to top it off, it has started to 'hunt' at partial throttle openings. Just does not have good 'carburetion' at say 3K putting around town. The chugging almost has a valve tapping quality to the sound. I'm a little over the 5K mark for mileage with no valve adjustment yet (due on the to do list). Thanks for any input/advice.
