That's very impressive for a bolt on part. Nothing shows in a search, do you have any contact information?

Yes, everyone in the dyno room was impressed too. I thought it was just another widget with outrageous claims, but you can't deny the dyno results and the track impressions backs them up.

The developer's name is Keith Peterson. He goes by KPRacing on thumpertalk. His email is keithpeterson75@gmail.com. I think he comes from a snowmobile and ice racing background in Wisconsin.

Haven't kept up in quite some time but is anyone still trying or have experience with the SmartCarbs. Weren't they supposed to have an updated version coming out?

Cool idea, excellent benefits if you could get it dialed in. Seemed to be a notch better than a Lectron when it came to not having to continually adjust it for changing conditions.

I wouldn't think twice about converting to a short body 38mm PWK air striker. I'd highly recommend installing a KPR Metering block while you are at it. The metering block made more power everywhere on the dyno curve and added 3-5hp at peak on my YZ carb equipped CR250.

Do you know if the carb off of a 2004 kx250 will work? I found one on ebay for a decent price but it has a bunch of electronics on it, which I assume I would plug up. Debating whether to do the air striker and metering block or a lectron for my 2017 tc 250.

I believe the pilot has to be much leaner to work with their needle, but my leftover slection of TMX jets from the '90's is limited. One 20 pilot and a few in the 40's and 50's. That's why I just got JD's new kit, but it only came with the 32.5.

I get the pinging at partial mid throttle/rpm in some of the sweepers at Hangtown when I raise the clip too far to compensate for the rich feeling at low rpm's. It's weird how it feels fat and almost blubbery down low and lean at the top at the same time.

Have you inspected your reed valve and how the reeds seal (or don't) against the block? Many KTM users are reporting the reeds aren't sealing well and having lots of low RPM/part throttle blubbery-ness.

My buddy is running a 37.5 PJ in his '17 250SX with stock needle on the 2nd clip. It runs pretty good for our conditions (sea level, 90 *F). I can't get him to try a leaner pilot yet, but think it would benefit from a 35 or maybe 32.5.

Hi eric_94... based on that carb set up from your friends at sea level ... do you know how many turns out on the air screw? It seems that main jet 450, pilot jet 40 or 37.5, clip in second position on the stock needle 43-73, and about 1 3/4 out on the air screw is working but between 1100 and 2500 ft above sea level.
MXA tested at Glen Helen which is almost at sea level and they only went up on main jet to 450 and opened out the air screw at 2 1/2. Has anyone at sea level tried this combo instead?

What do you guys think about the Lectron carbs? I see some people say they are plug and play, dork touch a thing. Other people are doing all types of adjustments?

What are your thoughts? Thanks!

i have one on my 250 and it's been great so far. Doesn't need hardly any adjustments, on the off chance it does it takes about 2 minutes to do and you don't even have to loosen the clamps. Main jet (Powerjet) adjustment. Is a screwdriver. Metering rod is easier that changing a needle. I haven't touched min in months, love it. Also the lectron customer service is some of the best I've ever experienced with a product. Super knowledgeable and no question is too big or too small for David. Best mod I've bought by far.

I think some people are thrown off by the price, or maybe they think their jetting is good or you're less of a mechanic if you get a lectron. Either way $400 and you will get the most out of your bike and some people will spend $1000 for a four stroke exhaust. Baffles me.
