250-500cc Lectron Carb

You allow a buddy to ride with you on a 250?

im back to my PWK, ill sell this 3hr old Lectron that i paid 330,00 for 250.00 and that's free shipping in the lower 48. If you already have a keihin dont bother it wont make a difference and i wont sell it to you, if your replacing a Mikuni its an improvement ( my experience)

How much to ship it to the UK as I need another ????

i dont know , ill have to check with the US post office, whats the address there?

Now you did try to replace a 38mm Mikuni/Keihin with a 36mm Lectron right? Just curious. The reason I ask is a friend replaced his 38mm Keihin on his 250 with a 38mm Lectron and his is vastly improved. It runs seriously good.

Yes its a 36, thats what motosportz sent me, maybe ill just contact motorsportz to take it back

I put a 38 on my 250 and everyday it runs better than the best day the Mikuni ever had and I felt like I had the Mikuni sorted. I still might have a little left in the Lectron but it's so good now I just want to ride it.

The 38 may be the ticket but why is motosportz pushing the 36?

I think the 36 is for small bore bikes,,the 36 mm is the throat bore a carb tappers down from the inlet ( air filter side) thats how you get the velocity ram air effect,,if you have a 300cc bike you have to match the air flow velocity of the same carb if your upgrading.. An engine lives on breathing you cant choke an engine of air.. No air no power its as simple as that..

Yes and so far the only unhappy customers that I have read about are those who bought 36mm carbs for 250-300 bikes.

I have a 36 Lectron on my 250 and it rips , way more power than a 39 Keihin , the carb is not the problem

The 36mm Lectron on my 250 works great. I thought the 36mm lectron flowed as much as a 38 mik or kie anyway?

I have a 36mm on a 360 and it was a big + over the whole range, bottom end is fantastic. Mine took me awhile to get it dialed.

The High needle was waaaay rich initially, but the Low needle was really close. I'm pretty sure I'm at 1 turn out (leaner) also.

My WR300 came with a 38mm, and I was a bit skeptical about running the 36mm, but it seems to be the perfect size. I think whoever wants to try one out should do their research first...I wanted to smooth out the raw power of my steed and as an added bonus, gain a little fuel economy, which is exactly what the Lectron did!
I can roll faster through the trails and not have any "surprises" from the massive hit the Mikuni delivered from the factory, because of all the years I've been racing, raw power and trees= bad news!! Do your research, do some practice sessions and get it dialed in, and you'll enjoy some smooth yet deliverable power :-)

I rode a WR165 (KTM 200 piped) today with a Lectron and it ran OK, but wasn't what I think it was hyped up to be in posts I've read on several forums.

I expected miraculous F.I. response and unreal over rev. In the admittedly limited ride it felt like a "slightly stronger on the bottom" 125. Not strikingly more, which is what I was expecting, just a little more. I plan to ride it back to back on a track next week so I can get a better feel for it but I gotta say, first impression, neither the BB or the carby was that much better than my 99 WR125 with TMX and PC MX pipe/silencer. I added a 51t to the rear from a 50t and honestly, I think that or another tooth out back might make them just about even.

That's interesting. Very curious how you get along on the track. Some guys like the harder hit of the 125. I know if you whack my 165 on the bottom/mid like you can with any Husky 125 you will be picking rocks out of your asss.

It is all in the set up , if you don't have them jetted right (to rich) they are pretty lazy

This 165 had a drool line as long as the silencer. I suggested it was fat too. He says the bike has done that since new, even with the TMX jetted leaner than delivered. We pulled the plug and it was dark but dry at 10 hours. It barely had any deposits on it after 10 hours. The mix is 44:1.

Maybe it is fat, (carb) he left it as it was delivered and it suits the owner just fine, vet "C" learning off road. Roll on at the bottom produced a surge that is better than my 125 but not so much that I'd buy the carb and the 165 and the pipe. Again, the jetting might be off and I only rode in a small, gravelly loop in my street bike gear. Still, I've ridden my 125 enough now to know what it does and doesn't do.

I'll post my impressions of it at the track where we can ride both my 125 and his 165 on repeatable obstacles, turns, straights, etc.
