1st question - I recently purchase a CB750A with the intention of triking it for my wife. I did a top end overhaul after discovering low compression in two cylinders. During the reassembly I broke one of the 6mm cam bearing cap studs and cannot find anyone who carries new studs of the proper size. Would it be OK to use a 6mm bolt of the proper length to replace the stud?
2nd question - What is the purpose of the carburetor solenoid? Is it necessary for proper operation or can it be removed without hurting performance/operation? The bike ran when I bought it but all the hoses on the solenoid were disconnected. I'm getting ready to clean the carburetors and am not sure what I need to do with the solenoid. Thanks!
