Here's what I have: it is from a K2, so the idle stop screw is on the same side as the K1 version (it swapped sides during the K4).
Many of the little bolts and other pieces have been sniped off this one for other carb repairs, and the cable crank is a little bit bent up, but you can either clean this one up and supply the parts from your old one to drop it on, or take the part off this one, if you want this whole rack lifter.
I can send it for postage and a donation to the forum: I don't know what the postage will be (since it just went up AGAIN yesterday), but can send that info after it ships. PM me your address?
