hi, i have a viper 700 and i been having a problem with it coming on the end of last year. I would be driving along and the machine would die out. The sled itself would be fine like it wouldn't shut off or the lights or nothen would die, but it was like i lost my throttle responce. I would have to let the machine come to a stop and let the rpms drop to idling speed. Then i could take off and it wouldn't happen for the rest of the trip, but it is just off and on. So if anyone has any info on this please let me know. thanks
