Everyone knows K&N made a filter for the XS air box. And...everyone knows they didn't make one for the XJ.
Well since I'm doing a complete performance upgrade to Zilla I had to figure out a way to install a K&N filter without going to pods. I don't want pods on Zilla because it's my road bike. Occasionally on one of those 3000 mile road trips I'll get caught out in the rain. Besides I don't particularly care for the look of indivdual filters.
This is a very simple modification. I took an OEM breather and cut the paper element out leaving the metal frame.
Then I used a K&N "drop in" panel style filter that was very close to the dimensions of the OEM filter frame. The K&N number is 33-2586. I ordered direct from the K&N website.
The width was exact. But the length was slightly long by about 1/4 to 3/8 inch. I cut it to length and used RTV to seal it in the frame. Then I used JB Weld to reassemble the frame cross-member to the frame.
In theory it should allow the engine to breath more readily...but I can't prove that. If I feel like it I do an A-B dyno run while the bike is locked down on the rack to see if there is any difference between the two. I'm not betting it will be discernable but ya never know.
