Earlier today i was riding my polaris Predator alone and i noticed it was making a weird sound(like i was in 3rd gear when i should be in second) so i shifted down and went to first and it cleaned up. About 5 minutes later it bogged WAY down so i shifted all the way down to first and it just quit. It was really hard starting but i got it going i rode about 100 yards and it quit again and it would no longer start. It is getting gas, and oil. It has a clean air filter. We brought it home and some how got it started but when u would give it gas it would die so obviously the spark is still good. I NEED SOME HELP PLEASE. thank you in advance.
