Just an update, the raptor is fixed. after cleaning the airbox and filter and removing exhaust to vfy it was clr. after reinstalling everything it appears to be running much better. I have no explanation but will take it. thanks

I know this sounds dumb, but my yamaha has a run stop switch on the handle bar which i never use, (I use the key switch) but this has bit me before. i over look it because i never use it but it will keep the coil from firing. after that i would try to find a schematic for the unit. Good Luck. Todd

I recently purchased a raptor 80 for my grandson for christmas. I am trying to make sure it is running properly. i have rebuilt the carb and adjusted the carb idle then the mixture to middle of where it runs rough and it runs great for about a min or 2. then it stalls out. I can usually choke it and it will start so i feel it is lacking fuel. the fuel shutoff valve has been changed and i checked it for good fuel flow. any ideas of what to check next. I am planning to vfy fuel float height tomorrow. I visually checked it by turning carb upside down when i had it apart and it looked level. any ideas are appreciated. Thanks. Todd

Make sure exhaust is not plugged, possibly the spark arrestor?

Good info for us newbies, Thanks

Good luck with the big bear, I just bought a 97 big bear 350, I really like mine so far. Seem to be great machines.

Very cool

Just bought mine to work around the house, but hopefully can start riding some trails in the near future.

Thanks for the manuals, that will be helpful for those of us with older quads. Todd

Sorry I see I posted in wrong forum, still a newby Todd
