Does anyone else feel like their bike is struggling 2-2.5k RPM? It goes from really struggling to...about to blast off at 3K RPM. With the throttle staying at the exact same spot. Notice every time I take off from a stop. It seems super touchy, goes from no throttle to riiiiiiiinnnngggg with like a mm of twist. Maybe it's just the break-in period and me keeping the revs low, but it is not smooth down low. Everywhere else, it's like butter. This is my first in-line 4 bike, is it normal?
