Obsolete carb parts

[1oldfrt]

Just got the 85 Aspencade back from my technician last night. Carbs are all set up and the plugs, which were 2 heat ranges too cold are replaced. Feels like a new bike!
Anyway - he tells me the long needle jet and seat which is in the middle of the throttle valve in each carb is worn and hurting performance and mileage. These parts seem to be obsolete. He is going to get Honda part numbers for me but the carb rebuild kits he can access come with most everything, but not these parts.

Any suggestions? I was hoping my first post would be one of welcome and not a problem. Thanks.

Thanks. As soon as I get proper part numbers I will try there.

Any others?
