Hi my name is Ernie and i just bought a 2000 Magnum 500 yesterday. Well i did every thing anybody would do when buying one, checking everything and riding it. I rode it for 10 minutes with no problems rode great. when i got it home i rode it for about 10 minutes again untill it died. I would get it to start right back up and ride a little longer. Well it did that for a couple more times untill the only thing it would do is idle. I got it back home checked every thing out, coil, spark plug and wire, bowl, seat, needle, jets, air filter, made sure the air box was seated properly checked all fuel lines, air lines, put every thing back together and no change just idle and when i hit the gas bogs down, but there was one time where i drove it for 5 minutes and ran strong and died again. The only other thing i can think of checking is the fuel filter. If any one else has any idea of what else i can check out or do please let me know thank you.
