Ive just bot a kawasaki Ultra 150, it seems to run alrite out the water but when i first put it in the water it wouldnt rev above 4000 rpm. After 5 minutes or so it seemed to clear itself and revs to 6000 rpm now. But now it seems to take a while to build up speed. doesnt do much when you first pull the throttle and then kicks into life. Can any1 help.
