I've installed the new Ms-3 rod this week an set height 49.75 mm It's within a 1/4 turn either direction. Kevin gave me a starting point which was very close
Have you tried going a little richer than shipped and than maybe turning in (leaner) the PJ 1/4 turn or so? Shoulds like you are slightly lean on the bottom.
I'm pretty sure the 38mm carb I bought for my WR250 came with the MS-3 rod. I'll look at it next time I have it out which may be never since it's running perfect.
What ever it is it's working great. I usually keep a notebook on tuning so that I can keep track of the changes and how they relate to air density altitude but the Lectron was so easy to sort out a notebook is not necessary.
I ordered the new cable an Kevin said new rod was out. As for the power jet tube hmm could that be milled down myself an what's the gain ? Very pleased with MS-3
Not necessarily a gain just a change if needed. It moves the PJ affect up further into the throttle and make it less effective. If you run your PJ more than 2 turns out it might be a good mod. Everyone who tried it so far likes it. It keeps the PJ from over running the rod in the mid range. Make sense? Glad to hear some feedback. Thanks. What did it do for your bike?
Ah gotcha as for new ms-3 I bought to clean up bottom will know after Sunday's HS seems snappy overall dialing in.the carbs been run 60-70 hard hrs. Hardly untouched with xl rod
First off I I have to thank Kelly for pushing through an overnight Lectron to me! Shipping wasn't cheap but I wanted it before a Hare Scramble tomorrow and had just decided to pull the trigger. All I can say is COOL! This carb is just flat out cool! I have a 13' WR300 ride 0-3000' I run a Gnarly Pipe and FWW with Rekluse and with the addition of the 38mm Lectron this is now almost as big of a cheater bike as my 570 Husaberg! I got the carb and went 3/4 turn lean before install. Put the unit in not a big deal, it goes in fine, took all of 3 min to put in the boots (push air side boot to back of bike while putting motor side into boot). Once in tighten everything up hook up fuel choked kicked a few times and thought oh boy I hope this wasn't a mistake, fourth of fifth kick started, tried to set idle and it would die out and bog a bit so you could tell it wasn't right. loosened the clamps tilted the carb to me and removed slide (did not have to take carb out of boots!!) turned metering rod 1 turn richer so 1/4 turn richer than out of the box. Was able to set idle and took it for a spin ran ok like old carb but nothing special. I noticed it would hang a little then idle down so I tilted carb turn rod 1/4 turn richer or 1/2 turn richer than out of the box, set idle, no hang. Ran it and WOW I had a smile on my face from ear to ear! I'm glad I went for a big change in both directions on the metering rod so I could see what it did, plan on 3 or 4 adjustments if you want to get to know your metering rod lol. One low, one high, one to get close, and one to get it right. write down your changes it's easy to forget where you were and where you started and where you've been!! write it down!! The smooth power was ON, this carb is F.I. for 2 strokes for sure. The Lectron took any hint of a "powerband" and sent it packing and left smooth linear power just like my 570 berg FI has! Twist the throttle and the power rolls on, very cool! I have a buddy who wants to try one on his KX250 i think and the way Kelly made it sound they can and have made that happen before so this isn't just for your husky!
Hey thank YOU for taking a chance on my opinion on something and for being a customer. It's all you man. Thanks for posting too. I like your thinking and enthusiasm. I agree, knowing what does what is important.
As many of you know, I love my Lectron. That said I have found the one way to ensure some agony. The only way you can flood your bike with the lectron is to shut it off when you take a tumble down the hill and the bike is virtually upside down. At the end of a long day of clearing trail I of course fell off down hill in the rocks and the 165 was chugging along upside down. It got shut off and by the time I managed to get my fat ass all the way back up to the trail I had a crankcase full of gas. The only way I can see it dumping that much gas down the motor is to actually start syphoning. Made a long day agony. It will idle away in any position so don't shut it off.
I'm 3.25 turns out on my PJ, and am excited to try the new rod as well (although my bike runs great as is). I had a problem where it would bog in the 3-6th gear fast stuff, with throttle WFO in a desert ISDE. 1/4 turn richer on the PJ, and it runs great everywhere... Sounds like you may be adjusted close to all the way out though. My bike likes a good amount of throttle to start as well. Kelly's seemed like it wanted a LOT of throttle to start a couple months ago, but not sure how it starts with the new rod. Not that a lot of throttle is bad IMO, if that's what it likes.
So I have a trouble shooting point to share. I went a little richer yet on the rod and put everything back together and noticed it just didnt want to idle anymore and seemed pig rich so took slide out and some how the rod had gotten pushed up and turned ever so slightly so the flat side wasnt facing forward anymore. I turned it back and put it back in, it was better but sill acting funny so I pulled it out again and it had done the same thing. If your having pig rich symptoms with poor idle or no idle then this is something to check! The rod and slide should glide in without pushing!
The new MS-3 rod makes it start way EZer, idle better, have better response and take a lot of the load off the PJ so you can run it as a fine tune at nearer one turn out. Just got more stock if people want to try one.
Will the MS-3 rod work with the 36mm on a WR300? I've got my PJ almost all the way closed to get it to run the best I can. I think the smaller carb flows faster and pulls fuel from the PJ early in the throttle opening on the 300. It seemed to have an effect much earlier than half throttle. Starting and idling are OK. Above half throttle its just hard to find any kind of happy medium.
I have really only tested it on the 125/165 bikes as the 250/300 seem happy with the 3-1xl. Sounds like all you need to do is cut your PJ tube to about .600 or .500 and try that. I have not heard of anyone running the PJ almost all the way closed, most have it open to far. Shortening the tube makes it come into affect later in the throttle.
I have exactly the same symptoms of hanging idle and float bowl sucked low or whatever it is. I also get some overflow on the cases below the carb as it makes a clean spot there, Hopefully the new rod will meter better and atomize better.
