I am going to put a snorkel on my V force very similar to the one that XC 800 has on his v force. It is a twin hose deal. I am currently running 138 and 142 jets at 5300 feet and am curious to know if I am going to need to up the jets or not. Not sure if adding snorkels will make me need to jet or not.

 

yes you will definately have to jet up to 155 158 or a number up or down depending on altitudes ect but those should be an almost perfect start if not right on. Don't forget to do a plug check or choke pull.

P.S 12 1' holes would give you a lot more performance gains.
