just put a custom snorkle 2", down to 1 1/2" over carb and into air box, i cant get it to run right , it pops and sputters a high rpm, i had a 165 main jet, and needle set on second slot from top, that's how i set it with the hmf exaust and it ran fine until i put the snorkle, now i have tried one bigger and one smaller jet and also tried adjusting the air fuel mix screw, and i'm having no luck at all, any suggestions would be greatly appreicated, thanks

So it only runs bad at full throttle? You need to adjust the main jet. Usually popping means its running lean and you need to install a bigger jet. Also, do a plug chop. Hit the kill switch at wide open throttle and pull the spark plug and check the color. White = Lean, Black = Rich, and Brown = Correct jetting. email me [email protected] if you need some help.
I built a snorkel for a 06 foreman and we only had to turn the air/fuel screw out some. It had a pipe and filter with a 165 main jet. Pictures of it are on my website
I dont have one but Ive snorkeled them. They are hella nice and I'd take on over a atv anyday!
