i was riding in the mourning, and it ran perfect. Then i went riding in the same place and day, but in the afternoon, and it ran like crap. It would backfire, stumble really bad, and just sometimes die. Is it running to rich or lean? or something else????

Have you jetted before? If not you need to jet if you running open air lid. Have you tried to check your PB wire?

If it was running fine one day and then not the next, I suggest you have fuel contamination problems or dirty carbs, start by changing fuel and then dismantle and clean the carbs.............
Another scenario is electrical problems such as a rev limiter engaging, PB or Reverse, this will cause rough running, check your reverse light if it comes on when the problem starts, it is does you most likely have a problem with the contact of the green and white wire at the reverse switch, clean and crimp it............
