Sorry, But I disagree... a lectron 48/50 WILL out torq and out accelorate a set of dualls with more consistancy.
The dualls when fine tuned to the max rev out good BUT take longer to reach higher rpm, but will not out perform the lectron.(on Gas) From what Ive seen, the dualls do better on alky"IF set-up right" than they do on gas.

I dont know for sure but I THINK 222 and mr hp have proven otherwise.

222 can you confirm>?
Both set-ups run good depending on tuning, I run everything on alky, and just have seen duals do better around here, JMO, it's all good !!!!!!!!!!!

I agree 120% It ALL comes down to tuning. Sounds like you can tune pretty good yourself.
I have seen dualls run great though around here too. It all comes down to the choice combo.IE, port, cams, pipe, carb.

You got it , I'm a tuning nut, people don't understand all the combo's out there a person can create,
one build at 800cc's won't even compete with say a 690 tuned right !

Most people are bolt-on or bolt-in's, I do everything myself, and am proud to run with or better than most top builders around here with an old XR air-cooled motor, I hold my own to say the least.

I have not got beaten with my single 48HV Lectron carb against a duel set up FCR raptor, dont plan on it either, and if any duels go on my bike they would be Lectrons anyways, The carb rips from top to bottom, the comparison from the duels or the single are the big factor for me, but once im pulling top end in 3rd beating a raptor with the same mods and he is pinned in 5th i got to give it to the Lectron, it impressed me for sure....

Confirmed! I've tuned dual 39fcr's to death lately. You won't find them on my race bike[img]i/expressions/face-icon-small-smile.gif[/img]

I agree tuning is most important. Now that we all agree. What would be easier to tune and keep tuned, duals or a single? Who would win, a dual set up tuned good or a single tuned perfect? I know I could keep a single Lectron tuned a lot closer to perfect then dual FCRs, at least on a raptor.
