Fellow lectron carb users opinions

[the gman]

This is not a carb bash so please don't, thank you very much.

I have tried many cast and billet carbs in the 38,40, and 36 style on my gas gas and ktm 300. I loooove the flat needle and think it is better than a stock carb as it only has a choke hole on the bell and no idle jet ,air jet, main jet ect to plug. I ended my season on a lectron 38 that I tried a 2-2 needle and finished on a 3-3 against the recommendation of the boys at lectron. Well it worked fantastic and with the quick turn after jet my temps Never climbed over 1150 on our last ride. I have a 36 mounted to my 300 gas gas that if snow will cooperate I will be able to do some comparisons with. If you have any testing done please chime in as I think I have been over boring ,over carbing my 300 and just going backwards.

Please feel free to share your experiences ...garry

i put a 44 on my kx500 and it gained 4-5hp through the whole rpm range. this was over a bored pwk 39 and measured at the front sproket. my cylinder is opened up quite alot vs stock, larger pipe, timing ect so mine may flow more air and benefit from a larger carb more than a stocker...but back to back it made good gains.

the vm44 made about the same gains, as well.

theres another guy around here that runs a 40 lectron on a ktm 300 and i believe it works good.

mine came set almost spot on. i think i turned the pj in about a 1/4 turn when we were running it.

What needle are you running.? Mine came with the 2-2 I think, will have to check my notes, but the smarty with the q7 seemed to have more midrange torgue but over temped wide open so lectron sent me the 2-3 or 3-3??? Can't remember and it ran the rest of the season flawlessly. I also love the see threw float bowl.

I haven't used it in the snow but I have one for my sons 65 and have had a 36 on my 300. From there I went to a billet 38 smarty on my 300 and a 38 billet on my 500... The 65 rips but is very dependent on engine compression as soon as you loose some it does not work as well... On my 300 it worked very well. Now I right from 30 degrees to 100 and from 3000 to 11000... I feel the Lectron with the power jet is some ways gave you more tuning for a Snowbike application since you are up in the upper Rpms... But the smarty was much more resistant to extreme environmental changes. At the end of the day it's cutting hairs which one I like more. I find since the change in Smartys ownership customer service is better. Lectron has always been great. I find with both the 300 likes rich rods. Once finding the sweet spot which I find is within 10 clicks one way or another I have not had to touch them.. Meaning there is a small window mine seem to be able to run well in but once you find it then your set. Funny enough my machine will run with all the different rods it is finding the one that works and you do not not have to touch it... I will add all of my engines are modified. I love the single circuits

Here is a video with wheels where you can hear how crisp it is... That is 2nd gear pretty slow without a hiccup. This is what runs the same where I live at 8000 at 30 degrees and here around 5000 at 70 degrees... The only thing I notice is it started at 20 degrees and it was very hard to start at the start... That being said the fuel Injected and Carbed 4 strokes were kicking just as long... The primer on the 500 has solved this problem but with wheels it does not happen enough for me. Also way more seat of the pants power for me.

Does lectron offer a heated collar or heated version for snow applications?

It's worth asking I know when I was talking to Kevin the owner he said if you gave him long enough it should not be hard to give it that capability..

The avid works just fine. You just have to make sure you bundle up the throttle tower of it will stick when breaking snow hits it

heated lectrons

I had to build heaters for both the Lectrons I have on snow bi'kes.

Lectrons don't seem to ice better or worse than the Keihin.

On my yz250 I simply wrapped copper tubing tight around the bell and that was enough heat for odd icing days, oddly that bike seems to run well in deep cold snow with or without the heat.

I machined a cleaner nicer aluminum block heater for my wr450 with a Lectron. I run it all the time, I don't even think about icing since I installed that........just make sure you have it plumbed so hot antifreeze is available.
