I sure wouldn't dream of using one on a WR450. The GYTR jet kit is about $75. and works. If you want perfection like I do send your carb off the Zipty racing and get all the mods done. You'll be a happy carberating camper.

I think the Lectron Carbs are good for the 2 Stroke machine. There true value is that there is no need to change the jetting on them in various altitudes. Two stroke have a lot more variance of jetting than four stroke. The FCR carb is the best way to go on the four strokes, unless you have FI. Then you have no jetting issues.

I use a Lectron on my ktm 300. Its a nice carb. Runs smooth. No adjustments needed. Nice mpg improvement.
I hear they have a 4 stroke carb now. If you don't like dealing with carbs, then call them.
If you don't mind messing with your carb, then save your money, order some jets and the other things needed to fix up the FCR. It will run just as good.

I've ran the Edelbrock carb on a couple of 450's with good results. A little hard to adjust but doable. But honestly, once you get the stock carb jetted correctly (with Yamaha stock parts) future adjustments are rare.
I just found these carbs and they seem very interesting. I have an 09 wr450 that needs to be jetted and I found this entire carb while just lookin around. Anybody have any experience with them?
