  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

125-200cc Lectron - Anybody Running a 38?

Caferacerman

Husqvarna
AA Class
Just like everybody else, I am considering popping for a Lectron and from all of the threads I have perused, it appears everybody says that a 36 or a 38 will suffice - has anybody tried the 38?
 
I have swapped back and forth between 165's with both the 36 and 38. I couldn't see, feel, or witness a difference when riding below 4-5000'. Literally no discernible difference. Now as you go up in elevation from there you will start to see the 38 perform better at larger throttle openings as the air thins out. The small bores don't have huge vacuum pressures and the less restriction at altitude the better.

Keep in mind that the 165 is not a high rpm screamer like the 125/144. If you are spending any significant time at higher rpms > 10K rpm then you probably will have a slight advantage with the 38 there. Hopefully someone with the 125/144 and experience with both can chime in.
 
Yep what Walt said. We usually sell 36's to 125 class bikes as they seem to work great there and 38's to 250/300 guys. I have a 38 coming for my 02 CR250 and will be testing and working on optimal rods for them.
 
I've got a 38 (original versions with 3-1XL rods) for both my brothers 144 and mine has been like the village bicycle, it's been on 125, 250, 300, and 360. I haven't tried the 36 on the 125, but it seems to run strong with the 38. The 36 would likely be a better fit I think, and I'll probably see about stealing the 38 from him for the 390, and buying him a new 36 with the new rod and milled body.
 
I used the 38 on my 165 all year last year and it worked great. Sold my old 2008 cr165 this week and ordered another 38 for my to be build 2013 wr165. I like carb that much and I want to try 38 on my 2012 ktm 250sx before buying another lectron for it.
 
Tried both the 36mm and the 38mm on the 125 144 and the 165, On the 144 it may of gained a tiny bit more right at the top with the 38mm. on the 165 cannot tell the difference at all, And the 125 also feels totaly the same bottom to top with either fitted.
 
I think the cool take home message is that there was no difference in performance between the two sizes at any reasonable altitude. Get to 7000' and above and the 38 helps. But below that the metering rod is so good at sensing demand that the bigger bore doesn't hurt the bottom end that I could determine at all. Very cool carbs once setup correctly.
 
Interesting ... but apart from performance, is there a gas consumption difference ? Maybe the 36 makes better MPG ?

Both typically get far better than the stock carb.

I'm about to slap this monster 40mm Lectron on my 83 XC500 :eek:

hay K hows the 4t lectron deal going mite need one 04 YZ250????
Should work great. Carefully measure the length of your stock carb before you order. I'm running Lectrons on my TE 250 and SM450R. Easy to adjust and you run just a single pull throttle cable, no push cable.

Yes, we will make them fit perfect. Notice the aluminum add on to the bell in the carb above, this is so it drops right on my XC500 husky. The other end gets modded too.
 
They make a 28mm but everything else about it is the same size as the big carbs. I looked into it for a yz85 and there is no reasonable way to make it fit.


Yes, exterior casting is the same so fitment might be an issue on some bikes. Thanks for the info.
