Need some help gentlemen. I rebuilt the top end on my 07 ktm 250 sx with a 300 sx conversion kit not long ago. Have maybe an hour on it. I also installed a jd jet kit on there. Stock pilot, 162 main, red jd needle using the 3rd clip notch. Bike ran great. I purchased a fmf gnarly pipe with the turbinecore 2 silencer and installed it today. I kicked it over and it fired right up. It idled for a minute or two, i then turned the throttle and it bogged down and died and refused to start back up since. I tried kicking it over and no luck. Any ideas?
