Has anyone replaced the air filter housing with a pod filter?
 

I'm a heavy guy and I have a knobby on the rear wheel, which means the tire bottoms out on the airbox. I'm wondering if I can't fix this by removing the airbox and replacing it with a UNI foam "pod" filter. Has anyone attempted this before?

Would it reduce or increase the intake noise that reverbs between the rider and the windshield?

I assume you've already maxed out your pre-load on the rear shock?

Yup. It's fine for the street, but not so much for off-road.

I have no experience with this particular bike but plenty of others and of cone filter conversions; intake noise is the least of your problems as it will totally throw off your fueling. It CAN be made to work but expect a lot of fiddling with your carb settings, needle positioning, main and idle jetting changes etc

No need for any of that with the RX3, since it's fuel injected.

I have the same problem as you charlie, that's why I ordered this shock and will see if it will come on, because I don't see any other solution.

Dang it of course, that's what you get for trying to be smart :doh: just have had such bad luck with pod filters I wanna stomp and jump on any that I see

The only issue I can see ... where is the air temp sensor located..
they are usually in the air box... relocating it somewhere else may
not give a correct reading of the intake air temp...

This is not the only problem, because the air box is connected to the crank pulley, also any reduction in air flow will weaken the bike (I know, because I tested), but the worst may be the noise, and the original box can be lined with rubber in the middle and make a slalom for air or put a mesh, such as it is in db killer to the muffler and it is quiet for this reason it is not worth replacing it you need to lift the suspension and do it right the shock absorber I ordered has already left Belgium and should reach me next week wait charlie only you shortened the swing arm and on the YouTube video the ukrainian did the same and when he put longer shock the spring rubbed against the engine and he had to return to the original swing arm size.

Seems like the easiest solution would be a shorter rear tire or slightly longer shock. If you go the shock route it can still be a gamble because a new shock might be 10mm longer, but have a 10mm longer stroke (some aftermarket shocks have more stroke than the stock ones) so you're back to the tire hitting the air box.

Yes it is, but if on the original shock it rubs against the air box, it will not change anything, remember that originally this bike has a rear wheel size 15 then changed to 17, after changing the shock you will probably need to lengthen the side stand.

Yep that's why a shorter tire would be easiest, but a slightly longer shock (compressed) is also a possibility... and you're right, that could require a longer stand and maybe longer legs too. Lol

The tire will not give much, because maybe 1 cm, and the motorcycle on the original shock absorber rubs with 1 Charlie, and I would like to take a passenger, and it comes out 1.5 Charlie, so changing the tire is a half-measure that will fail with a higher load.So you have to be prepared for different possibilities.

You're right, I didn't realize that those bikes came with such a narrow range of tire diameters. My tbr7 with the odd 17" rear tires have tires available in several sizes with several diameters, with a couple inches difference in heights. My bad.

So, the reason I'm doing this is because I did raise the rear suspension. I cut 6mm out of each dogbone and welded them back together. This gave me about 0.75" raise in the rear, which is a finger's width from bottoming on anything. I can get a finger between the upper fender and tire, and when the wheel is all the way forward in the adustment it's still not touching the airbox. This is with a 130/80/17 Kenda Big Block tire. When running a golden boy/SR244 in 5.10x17 the tire still rubs the fender but now misses the airbox (though it's VERY close). I did have to weld an extension on my side stand.

However, with the rear lifted this much the bike is VERY unstable at 70+mph. It has a dangerous wobble. I tried sliding the forks down in the trees as much as I could, but this only made it slightly better. The bike is also a lot taller and I am less confident when the trail gets nasty.

So, my aim here is to return the bike to the stock height (I've already bought the parts from CSC) and remove the airbox instead. My other option would be to buy the 19" front wheel and run a slightly-oversized 3.50x19 front tire. But that's quite a bit more expensive than going back to stock and throwing on a foam uni filter. A lot more work tho, that airbox doesn't look like it's coming out easily.
