huskyohilux Posted December 30, 2008 Report Share Posted December 30, 2008 Why did you choose the mikuni TM28 instead of the keihin pwk Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted December 30, 2008 Report Share Posted December 30, 2008 I finally went with the keihins and I love them. when most people upgrade carbs its to the keihin pwk's. they are by far the easiest to tune. so many people have them on such a wide variety of motors that usually someone can recommend jetting that will be damn near perfect. stock carbs are good carbs, but as far as mikunis go, stock carbs are the end of the line for me.

dajogejr Posted December 30, 2008 Report Share Posted December 30, 2008 I would disagree with that statement, having owned stock mikunis, PWKs (Gas and Methanol) and Lectrons (Gas and methanol) I think Lectrons are the easiest to tune. Here's why people are tuned off Lectrons: They don't understand how they work PRICE!!!!! And not many retailers out there. Said it before, absolute key is to get the correct Needle/metering rod. And you can call Packard or Fast By Gast to get the correct one for your application. Once you have that...tuning is a breeze. No more jets to buy, needles, pilot jets. You simply adjust the metering rod and open/close the PJ as you need to. From going to 80 degree summer days to cold, cold ice racing, my adjustments hardly changed on methanol. I think anyone who tunes methanol will agree it can be more finicky to tune than gas. And best yet...all adjustments are done from the top. Either you remove 3 screws to adjust the metering rod or you open/close the external power jet. And... By simply changing the metering rod you can switch from gas to alky and back. You can't ruin the carb by drilling dumps and mains, there's nothing to drill. Also, by changing the needle and seat...you can go from gravity feed to fuel pump and back. Any one of the few guys I've turned on to Lectrons love them. And as a matter of fact...two more are jumping on the bandwagon... They are 100% expensive....I completely understand that. But having used both PWKs, PJs (briefly) and Lectrons....I'll never go back. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted December 30, 2008 Author Report Share Posted December 30, 2008 My motor guy feels the same way about lectrons as well, he is very good at tuning them. My motor guy is also a Mikuni master. When we got my TM 28's, he ordered up all the right internal parts and gave them to me. I ran em and had to adjust the main jet 1 size and they ran great since.

rubberneck Posted December 30, 2008 Report Share Posted December 30, 2008 Dave, where would you get a set of lectrons if you were looking to buy a new set. My buddy has some on his stock cylinder 10mil, and after watching him tune them, I think i might want to go that route and sell my 39pwks. I am running gas Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 30, 2008 Report Share Posted December 30, 2008 I would go to one person, and one person only. Dennis Packard. Helluva nice guy, and he is the whip. He is also in this sport. Lectron only has two distributors that I know of....and listed on their site. Packard and Fast by Gast. I do not know if FBG does off road racing ATVS/bikes. They very well might. I do know Packard does. Loco....to your point of PWKs being easier to tune, I would answer this. WAY more people have PWKs, for my reasons listed above. They are a very good carb, no doubt. With a bigger user base, there is more info on them out there. Also more parts out there, more people have used and tuned them. I have to be honest....I was given my Lectrons from a member on the forums. Late last year..a member saw I posted I've always wanted to use Lectrons, they're just very, VERY cost prohibitive since I can get a set of PWKs for less than 1/4 the price (used...) He sent them to me. They were setup for a 10 mil twister running the 1/8 mile...so I had to adjust the metering rod just a hair for my 10 mil cub. And by that...I mean leaning out the needle a mm or two. He would not take a dime for the carbs...next day air'd them to me packaged like fine china. I am very, very thankful for that. I would've never spent the 700 or so for these carbs new (billet bowls, etc.) After working with my PWKs most of 2007, and Lectrons end of 07 and all of 2008...they are a better carb, easier to tune, more responsive, they run cleaner and crisper. Just about anyone that has rode my bike says the same thing...for an alky bike, it is crisp and clean. Snop...sorry to hijack your thread homie....

I used to run them and these old mikunis on my previous bikes. I just opted for the mikunis this time around. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 30, 2008 Report Share Posted December 30, 2008 Not sure who your builder is Snop, but I do know Kim @ K&T is very good with the Mikunis. Also a top notch guy to talk to. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted December 30, 2008 Author Report Share Posted December 30, 2008 Not sure who your builder is Snop Dyno Dave Roberts from ILR Performance. Dan Wade from Patriot Racing has also guided me on motor building too. He likes the Lectrons as well. Quote Link to comment Share on other sites More sharing options...

He worked on the stealth project at Boeing and he is currently a QC inspector for Boeing. Ironically enough, at one point Dave and Dan were working with each other at Boeing. :biggrin: Quote Link to comment Share on other sites More sharing options...
2strokespirit Posted December 30, 2008 Report Share Posted December 30, 2008 I am also a big fan of PC pipes. I run the same setup with only pwk 33, still very good bottom and good topend. I am curious what exh and transfer duration you run, just for comparison.. I know you would probably don't say, which is fair.. I would love to run my bike against yours to compare the bottom and mids, with my porting which is a low exh and qute high transfer the 33pwks perform better, believe it or not. The software I use showed that even this stock stroke motor with this setups WANTS bigger carbs and the bottom is still killer.. Great post man!

blaster2006 Posted December 30, 2008 Report Share Posted December 30, 2008 easy, overall, 1 is worst, 2 is middle and 3 is the best, for overall power... chart one max rpm was at only 50 HP chart 2, max was like 60 and it chart 3 it hit about 65 hp chart 1 = 1 chart 2=2 chart 3=3 im almost certain Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted December 30, 2008 Report Share Posted December 30, 2008 i ran a lectron on my cr500 banshee a long time ago. everyone was talking them up back then so i thought, fuck it why not.. i got it and ran it from k&t. they said it should damn near be spot on for what i needed. well it wasnt. the guys runnin the lectrons i hillclimbed with on their cr500's ran a totally different needle.. soo, i spent the money and bought two more needles for that carb. i got it running pretty decent but not perfect, with one of the needles. i jacked around with it for a long time and never got it running just right. i had called k&t, which were really no help to me since they had set the carb up with what they thought was right. i also checked my shit to some of the guys i knew running them.. still didnt run perfect. i actually had the stock carb for that motor which was a 39mm pwk.. decided to slap it on one day and see how it worked. after about 30 mins of tuning it i had it running better than it ever had with that lectron.. who knows? the other thing i didnt like about the lectron was the quality of that thing. shitty flat head screws on it. fuckin thing was junk. i had stripped a couple of them on the carb top.. for that kind of money i expected a hell of a lot more. i washed my hands of the lectrons after that.. i assume mine came from the same place packard and FBG get them so i dont know why theyd be any different. oh well..

dajogejr Posted December 30, 2008 Report Share Posted December 30, 2008 I sent Jeff my Lectrons to play with on his bike...but to be honest, he really didn't spend a lot of time with them, and he really wanted to dyno tune them to feel comfortable with them. Too bad you don't run methanol Tyler, I'd send you my set if I get down time for you to try again. Other than the straight screws on top, I think they're made of pretty good quality (One of these days, I'll replace those with stainless allens) But I take mine off every time after the track cause I brake clean my carbs inside and out after a race/event. Even though I purge the shit out of them...I still clean them before the next time i'm gonna ride...after having a PWK needle stick on me from methanol residue...I'm anal about that stuff.
