I would say the TM, just cause it doesn't have such a long throw to get full throttle, making it easier to ride on a track.

 

I agree with the throw. But not with any bog. Every Lectron I have owned has been far superior to the Mikuni I owned in throttle response. The one down side to the Lectron is, right at idle, it does suck it closed, Once you break that seal, it goes. I explain it like there is no 1/8 throttle, it goes right to 1/4. Not that bad, but you get the picture.

I am not sure where to go for more information about the lectron. Try google, and see what that brings you.

http://www.lectronfuelsystems.com/ I found a link.....

 

I took a quick glance through that link, I do like the idea of only having a metering rod and not have to deal with a main jet and needle, its all in one. but like you said, there's no 1/8 throttle which isnt bad for dune racing but motocross it would probably be nice to have all the throttle positions you can get. guess it all depends on what you do more, but the Lectron sounds awesome for drag racing.

 

WE LIKE THE DUEL TM 45S.. IN MY 2CENTS WE LIKE TM45S GOING TO 48S NEXT

 

I took a look at your dyno sheet, holy sh*t!!! the torque looks like it goes strait up! lol, awesome design! you know somebody or did you guys get all that stuff on your own? bet it's hard to keep those front wheels in the dirt!!

 

it all depends, tires, gears, sand... the intake was made by us.. just a couple of brothers that like cars, bikes, always thinking outside the box... you can bolt on all the performance parts you want, does not mean its fast??? if you cant tune it...
