hi peeps, im hopeing i can get some help, ive got a 99 bus and the bike spluters and acts like its runing out of fuel until it hits 4000 rpm? after 4 it runs fine??? and also would like to know if the small gear directly on the end of the starter motor is replaceable or will i have to buy a whole new starter? cheers for any help!!!
