As far as I know it didn't come stock on anything

cameron da river rat

maybe the ultra 150's

you had to buy that size aftermarket. 40mm was about it until the larger tripples needed more.

I bought one for 5 bucks, It was pulled off of a kawi 750 sit down if I remember correctly. This is the anodized blue carb correct? not sure if it was stock though I put it on my X2 I just sold...

wasn't stock that's for sure. And if you got it for 5 bucks, that's stealing it. They no longer import this carb to the states. I had one on my 550sx and it was great. I didn't even have to remove the carb from the ski to rejet it, just pull the 4 screws that hold the diaphragm plate on and they are right there.

BTW: The blue 42's are no different than any other colored Keihin 42's. Sudco bought a bunch of these carbs, painted them blue and put Sudco and racing only stickers on them. If you call sudco and ask what the difference is, they will tell you there is no difference. They are still great carbs tho.

Apples and oranges. You did steal that carb if infact you paid $5 for it. They are sweet, super smooth and easy to work with

Aftermarket carb. Nice score

Did a ts come with a kehin, and what kind of manifold do I need to put one on a pp 440?
