I have a 93 polaris 500 efi I have had problems with so I redid some wiring and cleaned up a bunch of stuff and put new exhaust manifold gaskets on bc it was making the motor all oily. Well I took it out ran it for a couple minutes and it ran great i was really surprized its the first time I rode it but wow didn't expect that. Well I shut it off and went to start it again and everything kicked out right and it wouldn't start. I thinking maybe im going to have to get a new battery? Any other ideas? Also my speedometer cable wasn't even hooked up when I bought it so I bought a new one and the old one was broke in the center. With the new one on it it still doesn't work? Could it be the bearing I have been reading about it doesn't seem to be loose but how hard of a job is it to fix? Thanks for the help!
