Need help IDing this carb

[Tedh98]

I bought a '98 KDX 200 last night. The owner said he put a different carb on the bike.

The inside of this carb looks a little different than the one that came on my '97 200. The needle was a DEK, I didn't see any numbers on the slide.

Is this an OEM carb or something different? Thanks for any insight.

kinda looks like an air striker

[Tedh98]

It sure does, thanks.

From doing a couple of quick searches, this seems like an upgrade to the OEM carb.

How does an air striker compare to an RB carb?

[scheckaet]

supposed to be a bit better than the RB mod, I thought about it before I got my RB carb but couldn't justify the price difference for the airsryker.

RB mods the airstriker too, for the supposed ultimate carb. Seems more beneficial in MX.
