Last night I did my season tune-up (power-valve clean-up, hifax, grease blah blah blah) then hit the field for a little romp. Sled ran for 3-4 mins. before I took off then about 1/2 mile to riding area, made a pretty fast run across the field and was turning around when I noticed the throttle was real boggie at low rpm pumped it alittle and it took off. I reproduced this several times. Went home and measured the servo cables they were good, checked the plugs they were warm and dry. Sled has 1600 miles on it BMP pipe mod, D&D y-pipe, stock can and high flow intake. The mods have been on there for at least 1100 miles with no problems. Any ideas would really be appreciated

Just cold dry air and she was off the pipe. Just a guess

Thanks Dono I'm on a 5 day/ 12hr shift stretch, gonna try and get out on Monday see if the condition persists. I'll warm it up good before I make another post.
