[Marunui]

Hi I found sometimes wen the bike hasn't Bn ridin for a few hours and I've got back on it starts up sweet then start riding nek Minit I'm coming up to lights or stop signs and she will cut off wen I'm stil trying to change down so then I clutch and start her up again and off she goes . The idol sound strong wen I'm starting the bike .but sometimes wen I ride it just cuts out sometimes I give her a couple of revs to keep her alive and it does work but does any one else find that with there bike she didn't do it wen she's hot and been riding for a hour or longer ......hhhhhmmmmm!:confused:
