Does anyone Know what would cause my Fourtrax's throttle to hang after giving it gas, and why it starts shuttering while trying to go in any gear. I wasnt having any of the problems up until i put a snorkel kit on it.Please let me know if anyone has an idea of what could cause all these problems. thanks

 

Snorkel intake pipe maybe to small in diameter[not getting enough air to airbox,,Did you rejet carb?

 

I haven't rejeted the carb. Is there a certain size jet?
