What size Keihin carb is on a 2000 FLHT?

 

40mm (CV40)

 

If you need a carburetor get a S&S

 

The Keihin carb is actually a pretty good carb, very underestimated and not respected, but all things considered, a good choice for most riding styles. That said, like Old Phat, I do like the S&S a LOT, but I also like the Mikuni, but if I had a good Keihin on my scooter, I doubt that I'd spend the bux on an aftermarket carb.


I know, that wasn't OP's question. But hey.

 

Mine has run flawlessly for 17 years. Even up to 11,000 feet in the Rockies. No reason for me to change. Just saying.
