Carburetor or EFI

Has anybody converted a 2005, or newer, Honda CRF450X to Fuel Injection. If so, have you gotten an increase in Hp, or Torque.
Is converting to EFI worth the time and money ?
Thanks for your input ...
Chet.

A well tuned carb has no disadvantages compared to EFI...UNLESS you are running at variable altitudes.

I am sure that will spark some feedback, but...its the truth.

Let a carb and FI bike sit for a few months with pump gas and see which one will start. Ways around it but I'll take less maintenance everytime. But if you have only one bike and ride it often not much impact. Except for your example above of altitude and that is only if you like to travel. Jet your carb for Houston and stay in Texas and you wont have an issue unless you're racing.

Put one of these on a carbed bike, and elevation won't matter.

So...
As I was digging around looking into doing fuel injection, or staying carbureted,I found out that I have a 36mm carb instead of the stock 40mm. Does anybody have a 40mm fcr, or similar carb that they would be willing to sell?

If it were not for ethanol tainted gas I would say no preference, but since non ethanol gas is hard to find/expensive I prefer EFI.
