dajogejr Posted October 14, 2007 Report Share Posted October 14, 2007 Awesome...all I can say... Had a great day at the track, got 15 to 18 passes in before the seam on my brand new pipes split...so, back to Matt for a warranty. I will give a full write up of pros/cons tomorrow...long day...

dajogejr Posted October 14, 2007 Author Report Share Posted October 14, 2007 I think my clutch is starting to go, too.... I think I may sit this one out...not sure.... I got a TON of runs in, I really can't complain.... Ok....without knowing a thing about Lectron carbs...other than what others have told me, and what I've researched, In can tell you this, they are awesome. I'm lucky enough to have mine setup by Dennis Packard for a similar motor, there is no doubt he is the top dog for Lectrons, if not, he's in the top two or three.... Having the correct needle is key. From there, you tune the bottom end first. Took me three times (adjustments) and I got it pretty close. Then...read your plugs and tune in the power jet.... No more changing brass..it's turn the needle, open/close the powerjet...you're good. The nicest part is you're taking off the top of the carb to remove the slide and needle, not the float bowl (spilling all that fuel ALL over) to change brass.... Honestly, I did a fair amount of research how to tune them, it's very simple. The only problem I have is the idle down problem. From what I understand, you either have to have holes drilled in the slides to it idles down properly...or get stiffer springs to they shut the slides. These have a nice, easy pull to them, so I think I'm gonna get my slides drilled...but I'll talk to Packard first. Within 3 passes, I had my bike running the same times I ran on my PWK carbs I've had all year. I actually averaged 1-2 MPH faster. Now....that could be the track, could be a lot of things...but I turned my best time ever today, best MPH and best 60 foot time....as well. If you can handle the price of them, I say go for 'em...easy to tune...and quite a few people told me they truly carburette cleaner...

chugger Posted October 16, 2007 Report Share Posted October 16, 2007 Good to hear that man I'm glad they are working that well for you. When i build my cub over the winter im gonna get a set of lectrons. what kinda times did you pull? lates chris Quote Link to comment Share on other sites More sharing options...

Ran low to mid 4.3's almost all day...and the track was CHEWED UP...they let a lot of jeeps/big trucks run too... Just as fast as my PWKs, I had to adjust the needle three times, a little bit leaner each time...and it went from 45 to almost 60 degrees in a few hours.

00tbanshee Posted October 16, 2007 Report Share Posted October 16, 2007 i got a good deal on a set of lectrons from a guy i knew and ended up selling them on planetsand.guess i should of kept them and sold my pj's Quote Link to comment Share on other sites More sharing options...
dajogejr Posted October 16, 2007 Author Report Share Posted October 16, 2007 The fact they were setup by one of the gurus of Lectrons, for a build very, very similar to mine gave me a lot of confidence to go out and run them. Everyone says the needle is key...Dennis Packard knows what he is doing. To be honest, with dual feed powerjet and large billet bowls, I really don't need a fuel pump for 300ft. However, dune races can go longer, one day I might hit the 1/8 mile...and I already had a fuel pump run and plumbed, with the exception of having to order a new throttle cable, it was a bolt on and go for me. Same intakes, same air filters, and if I wouldn't have messed with the needles (went rich to be safe...plus it was COLD) I literally could've bolted them on and ran... I like the fact there is no brass to buy or test with. Turn a needle for low and mid (which...doesn't have to be spot on for a drag bike that is at WOT for a few seconds) and and open the PJ to give it fuel. It really is a no brainer carb....

theshee Posted October 16, 2007 Report Share Posted October 16, 2007 What size lectron carb would you recommend for my 10mil motor Dave? I run a pump, and we race at 8500 feet. I have a guy that will trade my 39s for a set of 38 lectrons. Should I do it? Quote Link to comment Share on other sites More sharing options...

I have a guy that will trade my 39s for a set of 38 lectrons. Should I do it? Guy I got mine off of has/had a 10 mil twister setup for 1/8 mile. Mine are 40/44 (intake/exhaust...Lectrons are tapered) and the intakes are bored to 41.3 or 41.5...I forget. That's a tough question to answer...these didn't cost me anything, they were given to me. The fact they were setup for a very similar motor by the best in the biz...was a double bonus. I've run my bike at the track all year...and these carbs bolted right on, a little adjustment, and it ran just as fast...and even more consistent than my PWKs have all year. Mabye I'm getting better at tuning alky, maybe I'm getting to be a better rider and more consistent rider on my bike...I honestly don't know. It would depend on two things if I were in your shoes. 1. Who set them up, and are they setup for a similar motor, pumper, elevation you ride at? and... 2. Even trade, money out of pocket, etc. Mine was beyond an easy no brainer to try...and I'm happy with the results. Your call... As long as the needle is right, the rest is very easy...and no jets to buy, as said. Make sure you get the cable too...your stocker for the PWKs will not open the slides all the way.

theshee Posted October 16, 2007 Report Share Posted October 16, 2007 cool... thanks for the info. Im going to have to talk to the guy and get a bunch more info from him. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted October 16, 2007 Author Report Share Posted October 16, 2007 I'm not sure how much effect 38 vs 39mm carb would be.... However, I think if they're not close in setup, new needles from Packard, possibly seats and needles if they're not already setup for a pump.... You will need a set of dial digital calipers to measure the metering rod/needle length on them...you set them and go from there. 1/4 turn on the metering rod is roughly one jet size...so, plenty of adjustability... You just have to make sure the flat side of the needle always points toward the intake/motor. once you turn the needle, you push up on it to make sure the flat side is intake bound. It might sound weird...but get a set in your paws and it makes total sense... Quote Link to comment Share on other sites More sharing options...
No Limit Powersports Posted October 16, 2007 Report Share Posted October 16, 2007 Not all lectrons are tapered or hv as they call them (high velocity) you can get them either way. For alky dennis uses a pe-1 needle and we sell alot of lectrons set up by dennis and that needle has worked on everything from 350 cubs to 4 mill dm's to 10mill supercubs. For pump you need a 3.3 needle and seat with both floats on. If your gravity a 3.5 needle and seat and one float removed is all you change. A 38 sounds a little small for a 10 mill but would work just fine... Quote Link to comment Share on other sites More sharing options...

A 38 sounds a little small for a 10 mill but would work just fine... Another thing...when you setup Mikunis or Keihins...you will get a wide range of answers on how/what to jet. You're the 3rd or 4th person to say the EXACT same thing on needle choice and seat setup, pump vs. gravity, and the whole float thing. I've got the billet Packard bowls, I don't think I'd need to remove a float...but I don't see ever going back to a non-pump setup...either. I agree...bigger is better for a 10 mil, but...he'd be going from 39s to 38s...not a huge difference... I did not know, however...that they weren't all tapered...I thought that was a Lectron trait....thanks!! Another thing...he rides at 8500 feet...I think a 38'll work pretty good...since they don't need quite as much fuel at that altitude...

No Limit Powersports Posted October 17, 2007 Report Share Posted October 17, 2007 Absolutely if your pumping no need to remove a float in fact if you do you probably will get overflow which is baddddd!!! lol The billet bowls are great no need to worry about running out of fuel with the billet bowls and a pump. I think the 38's would work very well not sure if it would be a big improvement over the 39 pwks except for the tuneability. And yes you can order the lectron in straight or taper bore you just look on your carb there will be 2 numbers on one side that is the size of the intake and exhaust ie you can get 38/40, or 40/40 Quote Link to comment Share on other sites More sharing options...
theshee Posted October 17, 2007 Report Share Posted October 17, 2007 So I wouldnt gain any performane going to the lectrons? I dont mind tuning my PWKs, they are jetting pretty damn close now, I just adjust with the power jets. If Im not going to gain power, Im not gonna mess with switching. Ive have just heard that the lectrons are a good gain in power for drag bikes. Quote Link to comment Share on other sites More sharing options...
