Does any one know of any Dyno test results for after market Carbs for a 400EX or a built 440 kit.

I'm looking for some imput on a good carb, I know that TC likes the Lectron and Sparks likes the Kleihn. I'd like to some numbers or hear from some one that has tried diffrent crabs.

I still run a stock with the choke removed and have thought about having it board.

Thanks for any input...

 

I don't know where to find any numbers, but the majority of built EXs run the FCR carb from the YZF426.

 

There's only one carb out there that's worth the money in my opinion.....Keihin FCR. I'd get the 39mm.

 

Duncan runs Edelbrocks on their 440's. I have the 40mm on my 400 (and love it!), and I think there is a 42mm also available.

 

I believe the Edelbrock and Lectron carbs are very similar. In my own opinion, the FCR carb from Keihn isn't worth it.

I would definately go with a Lectron. A friend of mine had one on his 330RX, and it was SWEET. It seemed to require a little more maintence, but was definately worth it. Good luck on your decision.

Also, something a little cheaper... You can get your stock carb worked on. I know many people that have taken the choke mechanisms out, and had their stockers taper bored. Both seem to help alot.
