    I've been fighting my jetting all summer. 2016 YZ250X. I'm seriously considering a Lectron. Slavens is a dealer and he has a good price on them. Any of you smokers using one at altitude?

    I put one on my 300 XC-W but I haven't had a chance to really try it yet.
    A coworker put one on his too and he said that after the bike warmed up, it ran flawlessly over quite a change of altitude.
    He also reported that he used a lot less gas.

    I have heard nothing but rave reviews about it on Ktm 2 strokes.

    I have one on my 300 XC-W. It's excellent. I've ridden it all around the mountains. The bike runs great at any altitude and temperature. I can also confirm that you will get significantly better fuel range with the Lectron.

    That's what I have read....and you know its true if its on the internet! Any changes to the power characteristics? I have heard/read that the Lectron takes away the 2 stroke "hit" and gives a more broad spread of power. Yamaha did a great job of that toning down the X from its YZ brother. Smooth is good.

    It definitely smooths out the power band. It doesn't have any transition from one jetting circuit to another. It just has a single metering rod.

    So, its like changing from the red power band to the factory Yamaha blue one?


    Sorry, couldn't resist. My years on the parts counter have jaded me to the term, "power band".

    I think linear is the best way to describe it, the "hit" really isn't there. Power builds up progressively. Talking to the guys at Lectron they attribute that to the carbs lack of seperate metering circuits. I like mine.

    I placed the order with Slavens. Should be in on Thursday. Hopefully I can get it installed and get a ride on it next weekend. Greco boy broke his other collar bone last weekend and surgery is Tuesday. That may slow my roll this week.

    My uncle has one on his 2016 Husky 300 and loves it. Never has to fiddle with it at all says he notices a little tiny bog when he was riding at 10k+ in Taylor Park but it ran good considering.

    We just rode our 300s with new Lectrons at Taylor for a full week and to all altitudes and the bikes were great! (no bog in ours).

    I think they are just a tiny bit harder to start than with the Kehin, but its no big deal. Choke em for sure first thing in the AM on cool mornings. A few of our mornings were below freezing and up to prolly mid 70s during the day.

    On one of our bikes the Lectron was spot on right out of the box, the other was a little rich so we adjusted the rod.

    I look forward to not having to rejet all the time....yes...its easy, but it does take time. The linear aspect Ridefreak mentions is nice. EFI for a 2T!!!

    Oh...and mileage seems much better! We had alot of road miles in the one time I carefully measured fuel (prolly about 20 road, 24 trail) but I got 44 mpg and my son 40. Thats with very little wheelspin on the following route: Rocky Brook Road from Taylor River Road to Spring Creek Reservoir, then up Flag Creek, along Reno Ridge Road, down Reno Ridge Trail, a dash of Deadman, Cement Mountain Trail, Rosebud to Rocky Brook Rd, then back on the roads.

    Lectron showed up today! Old carb is off, but I'm not sure what to do with the electrics that plugged into the stock carb. I'm hoping to zip tie them out of the way just in case I sell the bike with the stock carb in the future. Fitment is TIGHT. Took a break from scraping my knuckles.

    No electrics on my old stock carb. :hmmmmm On our bikes I needed to get a special MP throttle cable cuz the Lectron slide is longer than the Kehin's.

    Fitment was tight on my Beta 300rr also, pushing the airbox boot back into the shock spring, but only when the shock was fully extended. In 100 hours, the boot rubber hasn't worn at all..

    I did some investigation and the electrics on the stock carb are for the throttle position sensor. I unplugged them and wrapped them in electrical tape. There was a rubber cover over the ends, so I taped that closed and zip tied them up under the tank. For fitment, I loosened the top of the sub frame and removed the lower bolts so it would swing up and out of the way. Once I did that, it was easy peasy. I routed the new cable up and attached it to the throttle assembly. As Dmac said, the Lectron requires a new, longer throttle cable.

    Once everything was hooked back up and the gas tank was filled, it started in 2 kicks. I warmed it up and rode around the block. Seemed to pull from a lower rpm, but the idle was a bit low. I adjusted that and loaded up for this morning's ride.

    A buddy of mine took me to ride St Charles trail west of Rye. I had never been there before. The trail was in really bad shape. Rocks, roots, shelves, and mud. Toughest trail I have ridden in quite awhile. From the base of the trail at 8000' to the top of the mountain at 12,000', I never had an issue with the carb. Very little spooge from the muffler and it pulled clean from way down low to the top of the revs. Always a one kick starter. Absolutely no complaints so far. Rode the entire trail and only used about a gallon of fuel.

    Very pleased!

    Saw a video from Morgan @ Highland Cycles in Montrose where he put the Lectron on a '17 Husky 300 and absolutely loves it. Sounds like a no-brainer upgrade.

    I'm a SmartCarb fan, have one coming for the XR650R too...the one on my 2012 Gas Gas EC300 is sweet. Plus the owner is cool and donates to the trails.

    They are called Technology Elevated now.

    I looked into the SmartCarb and from the info on the webz, it seemed like they were having issues with delivery, quality, etc so I dropped it from the discussion. I'm glad to hear that someone picked up the slack and is providing another 2 stroke solution. I'd be interested to hear how it performs on the Big Red Pig. I had a pig and only had issues with it above treeline. Anything below that and it was fine, always a one kick starter.

    Since I didn't get out of 1st gear last weekend, I've decided to try some more wide open spaces this weekend. I'll report back after a rip at Ram off road park and possibly Aztec MX. I'm curious to see if I miss the "hit" at the track. I've been known to get a bit lazy and need a burst to clear a jump. No problem on my 450, just twist and go.
