    [IMG]I have a 14 TC250. Been reading that the airbox air flow is restricted because of the sub-frame. I bought a few of the little uni-filter 1" filtered hole grommets to try and see if it improves the performance. Anyone else try this yet?

    I also have installed a 38mm carb from a 125. Now that made a significant improvement to the performance.

    hey, I am looking forward to your observation of the added air flow. I still run the 36 carb, 40 pilot, 3 clip needle and 165 main. It is a bit more top end rev, but still has the bottom and mid of stock; I still like the stock jetting my bike came with though, too. 0 issues.

    I've read about that mod but I'd be concerned about all the dust. They did it on the number plates if I remember right

    Air still has to go through the air filter no matter if it comes through one hole or 50 holes.

    Yeah I know your right. I just figured the only major change between a husky and KTM he's about to drill holes in :).

    Either way, test it for us. You're a good guinea pig for when I get mine :)

    I will this Thursday if the track is open. Lots of needed rain in the forecast. I will take a pic of where I drilled mine and post it tomorrow.

    One more thing to add about the carb swap. If you do go to the 38mm, you need to run a 40 pilot, 175 main, a Suzuki NECJ needle on the 3rd clip and use the slide from the 36mm carb. The guy who originally figured this out, Digger29, says if you run the above carb and put the V-force reeds it will make a huge difference. I haven't swapped the reed cage out yet.

    These settings work great for MX. I know must of the guys here are enduro types so you might be happy with what you have.

    Did your lap times go down with the added performance?

    I haven't clocked the times yet but my friend has a bone sock bike just like mine. You can really tell the difference between the two. I'd compare it to adding an aftermarket exhaust pipe to a Yamaha yz250 its that good.

    Dick's racing taper bores it to 39 if I remember right. Sounds like an awesome mod with all the tests I've read on the 250sx's over the past couple years. You're kind of past that point though, figured I'd write it down here so other people see some options.

    I figured you've seen that thread. I've read it a ton now. Not much out there for TC builds. After you're testing the air box mod. I need you to test nekken triple clamps, 300 kit, zip-Ty suspension, the husky parts blue hubs, akrapovic exhaust, and a factory services 6 spd transmission. Feel free to add to the list :)

    LOL, Well, the 300 kit might be doable:D . I installed the Factory Connection Oil Control Rings in the forks to stop them from bottoming and they work very well. The KTM cone forks would be nice to have but I think they cost more than the bike did. Speaking of that, I see RT&T in Muskogee has the 14 TC250's for $5999 out the door. A good deal on a great bike IMHO.

    Get on the Munn Racing email list. Factory parts go to 25% off frequently. It'd help with the kit you need to test ;).

    I'd called them. If you email them requesting it they'll add you to the email list. I'm on the list because I'm a member at ktmtalk. Which you could join and be enrolled

    I'm only assuming but getting more performance out of the Lectron would ruin the awesome fuel mileage and smooth throttle response. I'd ask Motosportz about it. He'll know probably better then anyone here

    Well I guess that makes sense then. Air flows never bad. I'm the kind of guy waiting for fuel injected 2 strokes :)
