125-200cc lectron or pwk 38 as carb for 125 wr 2011?

hi, excuse me for my american speaking but i am french. i want change my mikuni carb because i make a lot of extrem and i need torque and low rpm. they are a team in france who change all mikuni with pwk 38 as. i don't know the lectron carb but i see a lot of you change for this. Can you help me for make the good choice?

thanks a lot

I put a 36mm Lectron on my 2012 CR125 and it made more torque in the lower rpm's. I can't speak for the 38mm Lectron but you will probably be more than pleased from either.

anyone else can help me?

I can turn a wrench but I'm no carburator mechanic. I not sure if I even spell carburator correctly. So the advantange of 'set and forget' intrests me greatly. As long as it last forever more, I will never cuss it.
What maintainence is required?

Wash the outside when it gets dirty.

my 36 has been on wr250 for 3 months i'd buy again,would have rejetted stock carb twice within those 3 months because temp. changes

I have both carbs, (PWK and Lectron) I prefer the PWK

Maybe being in the same area as Brad, and not climbing mountains or dropping to sub sea level in the same day is the difference? I'm in NJ too and in the limited exposure I had, not wowed by the Lectron.

I would never go back to a pwk or a mikuni, in 125 144 or 165 trim there is no comparison, My mate Trig runs a lectron on his 125 and constantly rambles on how fantasticly his 125 works with the 36mm lectron - was running a 39 mm Pwk
Put my 38mm lectron on a mates perfecly jetted and sorted 300 gasgas over the weekend and he could not belive how much better the thing ran - more bottom mid around the same but way way way more on top, only problem is he is selling the bike or also would be joining the lectron club.
Must add that my first experience with the lectron was NOT a good one till I got it dialed in and have never looked back since, My perfectly jetted 37mm pwk on my 144 runs like a moped compared to when I slipped a 38mm lectron on ! Totaly shrieks at the top- and is generaly better from idle upwards.

I'll have my friend at the track tomorrow with his 165WR & Lectron. He has gone a quarter turn leaner on the rod to try that. I suspect it'll need to go a bit farther to get it right, or it is just what it is.

I'll be able to ride both back to back as can he. This should give me a better idea of the difference. So far it has better pull in the very bottom IMO, but I don't really ride a 125 down there and that may just be the 165cc kit advantage too. Apples to grapefruits kinda compared to my fresh 1999 WR125 but I'm still looking forward to trying it in a situation where I can make better observations.

hey im not knocking the Lectron, to me is as good as my well tuned PWK on an awesome machine,! but one things for sure,they both trump the Mikuni HANDS DOWN

Come on the mikuni has also its perfect moments

although a few with me in comparing the hours and hours chasing the sweet spot and next day shit because the weather changed

lectron ordered for me here (will save me a lot of time I hope)

Ive had two Keihins - 36 and 38 mm .
I am not really sure they are much better than the mikuni. I have swapped back forth a dozen times. There is a bit more of a hit with the 36mm but it may lose a a couple of hp at the top
I ve got the mikuni sorted and i just want to leave it alone - it fits better, cable works better and I like the feel of the top end
I havent had a bog issue since doing the CR ignition
I dont feel the need to go for a Lectron - yet

You don't have the iseu with changing weather conditions?

here it can run good in the morning but when a rain shower builds up the humidity can change very quickly in extreme forms and the mikuni is affected big time

same as winter/dry time setting (easiest and less issues with wandering off) and summer wet/humid time setting the base setting of the carb differs considerable

I am simply tired of changing jets on the trail in the wet season between dry, clouds building up, and pouring down stage of the weather it can be 2 sizes of main jets diferent to get near right, the top of the RPM range suffers the most.

R-J, same experience for me with the Mikuni. that's what eventually drove me to the Lectron. i would get the Mikuni super nice, then weather would change and bam, i'm back to being pissed about the carburation. elevation isn't extreme either.

this summer will be the true test of the Lectron for me.

We ended up going a full turn leaner to finally get it to be noticeably lean, then went back in a quarter richer. It feels better, snappier off the bottom but I'm going to say it... his bike, 167cc Lectron, feels like a KDX200 IMO. Between my 125 and his the bottom end is clearly better, but mine comes on and wails from lower mid on up all over it. His bike isn't slow, but it isn't fast either, LOL. Might still be off the mark I guess?

The thing about the Lectron, it is hard to really feel just the 1/4 turns, and his rod was unseated on a few occasions. You really have to use care putting the slide back in. If it hangs up on the rod, it possibly came undone and turns away from its correct orientation. Even at this setting, he is still dripping spooge like crazy, but I think his pipe is probably just full of oil at this point.

What plug colors are you guys getting, normal, light tan? His still looks dark, not wet but dark/black, a bit of tan/brown on the very inner electrode.

Maybe i

I probably havent ridden an early cold morning to hot day yet . Or huge elevational changes recently . I do know that the WRs different igniiton and heavier flywheel affects the way the WR runs - and amplifies any slightly off jetting many times .
Especially off idle - low to mid
CR ignition is my friend
