ok so when i had my cbr 600 f4i i would hear a rattling noise when i shifted up sometimes...same on this bike. it feels like when i shift up i must be doing something wrong. i know its me and not the bike.. i shift up and i hear a rattling noise..if i give it gas it feels like its in neutral cuz its just revving up. then i kick it up and then it gets in gear. what the hell am i doing wrong??? not engaging the clutch all the way in or whats the deal??? like i said..i know its me NOT the bike. when i shift up properly everything is fine. any advice????
