Brute force 750 snorkels

[TMONEY]

Installed new snorkels and found quad to run rough at full throtle afterwards, pulled intake pipe and test drove found same... anybody have any suggestions on what it can be?

A buddy of mine built his own snorkel and he needed two intake pipes at 2"
for each. It's on a 750 BF. It sounds to me like you are not getting enough air, but i could be wrong.

When I did my 650i I had to go to 2 2" snorkels.I was popping really bad.Now it runs like a raped ape.
