I had the opportunity to finally try this richer metering rod. I only have a couple hours on it at my local spot with no elevation changes. It feels meatier on the bottom and way better in the mid and the same on top. So far it makes the 3-1xl feel a little sleepy. I'll try to get a good trail ride with elevation changes soon and report about what kind of fuel economy I'm getting.
That mirrors my feelings as well. Another member here tried it and said it was to aggressive for him and went back to the 3-1 for smoother. Nice to have options. Works fantastic in my CR250 husky.
is this the same rod as the 3-2M as thats what i ordered from Kevin at Lectron last week? 'M' was just to designate Motosportz, Kelly? hope i orderd the right one!
Same one. I designed 2 rods. MS3 for the 125-165 class bikes. 3-2m for the 250-300 bikes. More aggressive mid and snappier bottom.
3-2xl update. Finally made it out for a good single track ride yesterday. I've got this rod dialed in really good now and definitely like it over the 3-1xl. I rode 67 miles of a combination 2 track and single track and never hit reserve! I couldn't believe it when I looked in the tank to see where the fuel was on the petcock. I couldn't believe after 67 miles there was only a 3" drip line from the spark arrestor at a 32:1 mix ratio.
Ohh more punch.. Errm cant imagine an improvment on the 1xl! May have to get a stocking filler for myself.
Bringing up an old thread here as it came up on a search when I was researching the 3-2xl rod. I'm running the lectron 38 and was using the 3-2m. I felt the rod was a little lean off the bottom, so i called lectron (I think I talked to Kevin, not 100% sure on the name?) and he suggested the 3-2xl as the next richer metering rod, and if that wasn't enough then try the the 3-3. So I ordered both the 3-2xl and the 3-3. But, if this thread is correct, I wasted my time getting the 3-2xl if it is the same as the 3-2m I already had. Any idea as to why lectron would have directed me to the 3-2xl when they knew I already had the 3-2m, if they really are the same rod? I wanted to learn as much as I could before I called lectron back and asked them the same question, so thanks in advance for any responses or information.
Hey guys hope you don't mind me posting some questions here? I have 2012 GasGas XC300 I have installed a Lectron carb I purchased from House of Horsepower. I live at 1100 ft ASL, I have the 3-2Xl rod and it runs perfect throughout the entire range, but yesterday I took the bike up to 9000 ft ASL and at first it was rich, so I turned it our 1/2 turn leaner bike would not run at all, so turn in 1/4 turn better but still rich off idle w/ burble and slight hesitation. I feel as if the rod had 1/8th turn adjustments it would be perfect. Anyone have any ideas or thoughts as to which way to go, maybe different rod size?
OK with no responses I went ahead and called Lectron and talked to Kevin again. He said the 3-2m and the 3-2xl are definitely not the same rod. The first number, 3 in this example, designates the mid to top ratio, the bigger the number the richer the ratio, and the second number, 2 in this example, designates the low to mid ratio, again the bigger the number the richer ratio. The "xl" is for extra long, meaning the rod is long enough to work in the larger bore carbs (30-48mm). The "m" stands for modified. The modified means it falls between two of the xl rods. For example, the 3-2m is slightly richer than a 3-1xl, but still leaner than a 3-2xl. So, a 3-2m is sort of like half way between the 3-1xl and 3-2xl, (getting richer). Hope this helps future searchers looking for info on these rods.
Correct. I designed the 3-2m rod for the 125/144/165 bikes but it works well in other applications to.
A little confusing, per your response in post #4: "Same one. I designed 2 rods. MS3 for the 125-165 class bikes. 3-2m for the 250-300 bikes. More aggressive mid and snappier bottom." Now your saying the 3-2m was designed for the 125/144/165 bikes? I thought that was the MS3, and the 3-2m was for the 250-300 bikes. Not trying to be a pain, but do want to have the correct info out here. Thanks.
Copy that, I spoke to David at Lectron today. The 3-2M was his recommendation as well. And to confirm what was already said, the 3-2 XL and the 3-2 M are different. I can post a follow-up when I get the rod if anyone is interested?
I would be interested, if just to get a gauge on how big a change there is between the different rods. I am going to other way, from a 3-2m to a 3-2xl, the m was a little lean on the bottom for my bike. I guess motosportz is not too concerned with clearing up the metering rod confusion. Kind of surprised, this used to be a very active, dynamic site. Now it seems sort of slow and inactive.
Anyone know the stock rod number from a lectron 36mm carb from when they first came out. 2013? My lectron seems a little soft on bottom. I have it in a 2012 wr300.
