Need an intake for 2002 X1 W Lightning

[SauceSquatch]

So from what I could tell the bolt pattern matched up to CV carb intakes, so I found one that I liked that would give me enough room to drill in the air temp sensor in the back and turns out it's way too small. The CV intake looks like it's 45mm while the X1 EFI intake is 56mm.

Trying to figure out what to shop for here, the intake is the last thing I need to get going to fire this baby up!

since photos help...

I have this same bike. I also plan to upgrade the intake. Wondering how yours turned out. And if you could give me any information.
