Pod Filter - Removing Stock Air Box

(1/2) > >>

fletcjk:
Hello all I am new to the forum and this is my first post.  I picked up an '82 FT500 for $300.00 and I am slowly combing through it and replacing anything questionable.  I am going to change the jets and sprocket, but I'd also like to remove the stock airbag and replace it with a pod filter.  I can't find any information on doing that here on the forum so I thought I'd start a thread.  Has anyone done this?  What kind of results did you have?  What filter did you use?  There are plenty of small generic pod filters on Amazon pretty cheap, but I questioned myself due to the fact that nobody else had mentioned doing this.  Any help would be appreciated!!  Thanks!

Welcome to the board.

I have a stock FT with the OEM head-pipes & a straight through glass-pack type of muffler. I removed the air box & used an oiled foam UNI filter. I had already performed the jetting swap like is described in the FT Ascot Essentials, but I still need to add more fuel. The engine breaks up a bit in the 3800-4200 RPM range if I recall correctly. You will also need a small breather filter for the crankcase breather. I used one of those small generic K&N type of filters with a mounting screw in the top. I mounted this filter from one of the original air-box mounts at the top left frame rail & then ran a hose from the crankcase breather port to the filter. I'll post a pic or two below of the crankcase breather.

When it comes to filters, I don't trust the K&N screen & gauze type of filters. They allow fine dust to pass through & sucked into the intake tract. I much prefer the oiled foam filters like the UNI.

You can easily run a pod type of filter, but you will need to adjust your jetting. If you remove your air-box, you might lose your battery mount & one of the side panel mounts. I can't remember for sure on that.

Good luck & please let us know what you find out.

I made an adapter to fit a large K&N filter to the stock rubber boot. Like J mentioned, the stock air-box acts as part of the battery mount, so you will have to do some fabricating. I ended up using something like a 185 main jet. BTW, I removed the filter and boot after logging a few dusty miles and found no evidence of dust inside. :)
