I am new to the concours forum, but have view many times and fout very helpful info.
Problem: 1986 concours (california model) starts and idles perfectly. I just rebuilt the carbs, did valve overhead. I paid
special attention to make sure all passages in the carb were clean and carb cleaner flowed through them. Float levels set
right at bowl part line. The bike starts easily and idles well but will bogg and nearly die when given 1/2 to full throttle
(sitting on side stand in neutral). Revs will climb past 4k if throttle rolled on very slowly, but engine will not maintain RPM
past 4k and this seems to me like a fuel starvation issue or ignition timing not advancing. I've checked the diaphragms but
cannot see any pinholes, but it sure feels like its a vacuum problem. Fuel seems
to be flowing fine no kinks or restriction in lines.
Can anyone help?
Could it be electrical/ignition? I am getting frustrated, not sure what else
