Trick intake mod 400EX
#1
I was cleaning my filter one day and noticed a clean spot on it where it rests on the white intake tube. So I cut the indented flat shaped area out with a pair of shop scissors (2x3 square). It is a wasteful design that covers about 6 square inches of the filter. That is like 15-20% of the filter surface area. Next time look in there trim the snorkel tube so you can get more air. It just makes sense. I run a K&N so it may be larger than stock? Be safe!
