what would this be? im cruisin along in usually any gear, nail the gas... then pop wahhhhhhhhhhhhhhh it kicks out and revs like a mofo! after the rpms come back down it slips in and i can keep goin. also when this happens if i quick push the shift selector sometimes it will go in sooner. otherwise i have to ride around holding the selector down or up the whole time. please tell me what i need to fix it if you know! thanks!
