Hi I recently picked up a nice 03 Predator 500 for $800 At the time the only issues were it had a rip in the seat, a stripped shifter and the grips were worn out. Now I have a new seat on it but heres my issue. When you come right on to it it bogs around half throttle then feels like it has no power. Then if you keep holding it pinned it comes out of it and rips. It just started doing this. It idles fine and I cleaned the air filter but the problem is still there. It also is not charging the battery. If I ride for a long time and shut it off when I go to start it the fan comes on then slows down when you hit the starter and it cranks slow and wont start. And does any one have a shifter they would sell cheap?
