I am a new C109RT owner as of November 09. I just made it to 600 miles and ready for my first service. Already dealt with oil perking. I advanced from a C50 to this beast, and I love it. My question to all you veteran 109 owners is..... It feels like I am lugging the engine all the time. Any crusing speed any gear and a slight turn of the throttle and it feels like its lugging. Even at 80 mph 5th gear the whole bike shutters and vibrates until speed is not increasing. The dealer says its just the characteristics of this bike. Any and all feedback would be appreciated.:dontknow:
