Air filter/airbox setups

[gtilley45]

What kind of airbox/filter set ups are all of ya'll running? The way it is done on my CRF is a little too rigged up for my liking and I'm trying to get ideas. Anybody have any experience with the K&K aluminum airboxes? I was talking to a guy that used to have one on a LSR/CRF and he said it worked well with the no-link rear end. Here's the only pic he could find of it.


I talked to another guy that had a LSR/YZ hybrid and here's the setup he had.


He said it was a radiator hose off of a backhoe, and a YFZ airbox eliminator kit from ESR. I like the looks of this but, 1) will this be any better than just getting a filter that clamps on the back of the carb? and 2) I don't really want to use a K&N filter, I'd like to stick to foam.

The way mine is now, it has a short metal tube with a rubber clamp that clamps to the carb. The metal tube comes to about even with the rear shock, then it has a LT500 air boot connecting the metal tube to the 250R air box. All of this doesn't really fit together that well and it's a pain in the butt to take off and put back on. I will try to get a pic or 2 of it tomorrow, it's dark out and there isn't enough light in the garage for me to get a picture now.

heres my set up.

K&n filter with a bracket from jlatv. Then the intake tube is just dryer vent tube.

Here is the one on my CRF250. Custom aluminum megaphone tube, some radiator hose and a 400ex stock air box I modified.

outacontrol- That looks something like I need. What kind of aribox and air filter are you running? I was thinking about trying to make an airbox our of aluminum or stainless steel, and then going to an exhaust shop and have them bend me some tubing to go from the box to the carb.

[outacontrol]

its a 250r box, the only mod to it was having to cut out a small piece on the bottom of the box where the chain could hit it when the shock compresses. The tube was handmade by mark baldwin and it allows me to use any 250r filter. hope this helps some, i can take better pics if you need me to

[gtilley45]

Yeah, if it's not too much trouble I'd like to see some more pictures. Do you know if Mark Baldwin still makes those tubes?

mine looks almost the same as outtacontrols except walsh made mine, not sure if they still make them though
