LECTRON 38HV CARBURETOR REVIEW
Words & Photos by Rob “The Rake” Dunnet
With most racers riding fuel injected four strokes and the rise of KTM and Husqvarna’s TPI bikes on the enduro scene, there isn’t much reason to be dealing with jets and needles anymore. Despite the advances in technology, there are still a lot of riders who are fans of carburetors, riders who don’t mind adjusting needles, jets and mixing fuel. But like me, there are a lot of riders who are tired of dealing with jets and needles.
I spent most of the spring and summer changing out needles and jets trying to get my 2013 KTM 300 XCW to run right. I was constantly taking the carb off my bike, cleaning it and making small adjustments. I was fed up with it and decided that it was time to try a carburetor that self-adjusts. After researching the two most common smart carb brands, I decided to order myself a Lectron 38HV.
Would a new carb solve my issues? Let’s find out.
The Lectron 38HV uses an adjustable metering rod instead of needles and jets. The carb has a tapered bore that squeezes the air as it enters the carburetor and creates fuel lift behind the flat metering rod. The Lectron is easy to adjust and claims to improve performance and fuel economy, all while making power delivery smoother.
The Lectron comes with a throttle cable as the stock throttle cable doesn’t work with the Lectron carburetor. Installation of both the carburetor and the throttle cable was relatively simple. The Lectron carb is a bit longer front to back than the stock carburetor that came with my bike. This extra length caused some fitment problems with my air box and air box cover. As a temporary solution I pulled everything back into place with zip ties. I rode the bike like this for a couple of months before searching the internet for a more permanent solution.
After searching a couple of KTM forums I found the solution is to cut the air boot back to the second flange. It took an hour or so to trim my air boot and reinstall everything. I was a little bit worried about the air boot to carburetor connection and I have been paying close attention to it. It doesn’t seem to be causing a problem but I may end up ordering another air boot and making a different shaped cut to it so there is more material at the bottom of the air boot where it connects to the carburetor. The cut solved the air box and air box cover problem and everything snaps into place like it did with the stock carb.
