I got a beast of a bike and i am in love with it. the only issue that i am having is after riding it for a while, it will decide it doen't want to shift. when hauling ass, when i go to shift it feels like there is something blocking it from going into the next gear up, or it feels kinda spongy........i guess thats the best way of explaining ghe feel and if i slow down a bit then it will shift fine. i have been riding for a hot min and i am sure that it is not operator error, so leave the sny marks out. i broke the bike in and changed the oil aqnd then again after my first ride, and i am going to change it again before i ride again. i am wondering.....is this just a break in thing or is there something wrong.
