like the subject says, 87 Duke five speed, wants to die at idle in neutral will stay running if I give it done gas though. any thoughts?

Bad gas or a slight restriction in the injector will do that. Low fuel pressure may do that.

Bump. I have a similar problem waiting to see what everyone says.

update: I think it was an issue with my IAC. When I rebuilt the top end, I accidentally routed a wire bundle too close to the accessory belt and it sawed through a solid blue wire, which I was told was for the IAC. Like a dummy, I took my sweet time repairing it. I finally pig tailed a repair wire there, and it seems to have fixed it for now. I really need to solder it and put in some heat shrink butt splice connectors, but clearance there is pretty tight and I don't think I can get a conventional set of crimpers in there.
