I've got a 107 built from a 96 ,. Would there be much to gain from going with an intake such as a big sucker compared to my stock airbox with a drop in kn style filter I currently have? Bike has se204 cams and stock heads so it doesn't rev all that high but torque and mid range is great Might be influenced by the exhaust which is short shots with quiet baffles.

 

You need an entire high flow air cleaner not just a change in the element so yes get a Big Sucker or anything that's an equivalent. Also get rid of the short shots and pick out a good 2 into 1 exhaust set-up.

 

Ya I'm waiting to score a good deal on a 2:1 exhaust. Short shots came on the bike. A decent 2:1 exhaust costs more than the 107 and cams since I did all the work.
