Thanks Chris that was the confirmation I needed.Gee, it is a 1975 that he picked up for ignition parts. It is nearly 50 years old. Why should he rebuild it?
I say run it, if you need to.....
I just disassemble the carb and blow out the carbs with some spray carb cleaner. Make sure to get the small holes just inside the throttle plate in the carb throat. Those are the idle circuit.
I would not expect any significant loss of performance. 90 PSI is pretty good.
On your '77 1150. The inner exhaust covers and exhaust baffle are a PIA to get them to seal after all this time. Make sure they are flat, and you may want to use gasket dressing to help with the seal. If you have not disassembled it yet, those 5/16" exhaust cover bolts like to break. Use some heat and impact to try to loosen them. They were epoxied in at the factory.
I didn’t pay any attention when I had the cover off but it looks to be missing in the attached picture.Typical damage .----rebuild it now or it will be 10 cent / lb soon.----Are the bleed inserts there or gone like most of them?
Chris thanks for the heads up. I have not started disassembly yet as I didn’t know exactly where to start.I just disassemble the carb and blow out the carbs with some spray carb cleaner. Make sure to get the small holes just inside the throttle plate in the carb throat. Those are the idle circuit.

Fazt,Wasting your time and money....either pull it down and fix it or part it out. Trigger most likely bad as cylinder had preignition and now has WOT misfire.
