What kind of performance can one expect from a 40mm Lectron Carb for the 400EX? Thanks in advance

You can expect more performance from it than any other carb. And you can buy them new for 230 bucks.

 

In my opinion, the 400 MM carb is way too big unless you got one hell of a big motor, you are gonna lose a lot of needed low end with a carb that big, I'd personally stick to a 37-38mm carb.

Where can we buy a 38-39mm Lectron Carb for 230 bucks?

THANKS FOR YOUR HELP.

 

You can buy them for that price at this website.

Then click on Lectron Power Jet

The price is $239

 

i dont know what u can expect from the it on ur 400 but i have one on my 250r with a 275 stroker and i love it.i race harescrambles with it and have never had a problem and it still has plenty of low end.but i heard there a pain to adjust.thats the only problem i have heard of.i bought my quad a year ago and the carb was already on it and adjusted and i havent had to touch it yet.

What is the one that I have to buy (TRX400EX):
The Non-Power Jet (gas) or the Power Jet(gas)?.
Can I use my OEM Thumb Throttle?, because I don't like Twist Thorttle on my ATV.
And the last question, I have a 440 kit, with XR400 cam, ported, valve springs with titanium retainers, xr250 CDI and full Curtis Sparks exhaust, what size of carburetor do you recommend (I don't want to loose my bottom end), 38 -39 or 40mm?.

Sorry for those many questions, and thanks for your help, I really don't want to waste my money.

 

E-mail racer's edge to find out if you need the power jet or non power jet. Tell them your mods and see what they say about what size to get. I say if you don't want to lose any low end power to go with the 38. The 40 is more for top end speed.
