yzf750 the rev counter goes to 9000 and back to 0

i know this is telling me the exup valve is not functioning. how can i bypass this so the rev counter works normally ?

Have you removed the exup? if so reconnect the motor only and jam it under the seat. If not you will need to do something like this www.r1-forum.com/forums/46-how-tos/279726-how-diy-exup-motor-eliminator.html
