YZ 125

Product Code: 1451-HV

Availability: In stock

YZ 125

* Required Fields

  • Description


    This kit includes the 38HV Lectron and a throttle cable. The adjustment tool is highly recommended in case you have to do any tuning.

    IF YOUR DIRT BIKE HAS A THROTTLE POSITION SENSOR simply follow the plug up to the harness and disconnect it. It is not required for use with a Lectron. It is recommended that you wrap the plug in electrical tape to prevent dirt from entering it.

    *Lectrons provide superior throttle response and power delivery by utilizing our patented metering rod.

    *Our simple design does not incorporate multiple jets to replace.

    *Our taper bore squeezes the air to increase speed and create fuel lift behind our flat metering rod.

    *Lectrons are a great choice for riders seeking performance, fuel economy, simplicity and smother power delivery.

    Depending on some set ups, your air boot may rub on your shock spring. This is not an issue as the spring doesn't move enough to cause wear. 

    We do not recommend running a reed spacer. They may cause fitment issues, and the longer body of the Lectron compensates for the longer intake tract.

    Note: All carbs are built to order and have a 7 day build time, however, some orders will ship sooner.

    By submitting an order for a Lectron product, you are agreeing to our shipping, cancellations, and returns policy.

    38HV for YZ144
    02 YZ 144 ported for mid to low, running pump gas. Definitely some of the best money ive spent on this bike, after alot of time trying to get the mikuni just right i finally threw in the towel - After initial adjustment ( 1/4 turn on idle screw, 1/8 turn on power jet and 1/4 turn on needle) the bike was super smooth, fuel mileage is way better and it feels like it has more overrev, havent had the chance to test for real altitude but ride between two different ares: near the ocean (sea level 50 degrees and foggy) and inland ( couple hundred feet 90 degrees and dry) and its been perfect every time, plug never looked this good. (Used to have to swap main jet every time and sometimes foul a plug) Very happy with it - to anyone who has been on the fence about it, go for it - totally worth it!

    38mm HV Carb for YZ125
    This review is for 38mm HV Carb for a YZ125. It was best and simplest upgrade I have ever done to any dirt bike I have owned and by far the most worthwhile. I do not have to rejet the bike, it is as simple as that. Plug readings are perfect, perfect throttle response. Have used it so far in sub 32 degree weather and 85 degree weather, only thing I adjust is the idle screw. Even if you are an expert at jetting, you can not match how much more useable power this carb will give you. Also it is very fuel efficient, and if my bike is laying over it does not spill out fuel (for me), just another random plus. Will pay off itself in fuel savings very soon. Very pleased customer. Nice job Lectron.
