Hi i am looking to replace the Keihin 38mm PJ on my 86 CR250 with an Keihin Air Striker. I would like to find a used one . What should i be looking for as far as what year and make of bike may work and what jetting to start off with. Thanks for any help

As I wrap mine I'd like to know also. I'd assume start with stock and see. I'll ask a engine builder their thoughts...
As cheap as a new carb is (-200.00 @ jets r us) I'd be hard pressed to buy used unless its pristine and cheap.

I'm currently installing one on my '85 CR250. I let you know the jetting specs asap. I'm starting with the jetting from my original PJ carb.

Buy this Airstriker already jetted from Honda for a CR 250. Good starting point I would guess.
