I have done the search and found one post with the guy having the same exact problem, but did not post what fixed the problem, some people said to check the parking brake switch, I did a search on that and nothing. The bike starts up right away and idles purfect. the carb was cleaned and the plug is new. still doing it. I am running 145 and 150 main jets and 25. pilot. I am at 800 ft elevation and the A/F screws at 3 turns out. Please help with this problem
