The BIlletron 38mm Carburetor from Lectron Fuel Systems


This sucker is mean & packs some serious grunt off the line, as tested in mXrevival's YouTube review video 


Per mXrevival's track test video above:


-Not only does the new Billetron SPANK the old Letcon's bottom end power offering... but to us, it also runs like a perfectly jettet Keihin Carb..... WITHOUT JETS.


-All the great lecton features you've grown to love are still present too.

-No jetting, ever!

-No need to worry about temperatute or elevation changes

-Our 2004 RM250 hauls serious ass with the new Biletron installed
