Need help.

[Jimongee]

I have a 1982 Honda cb750. the engine is out of the bike. I don’t have a jump battery. This model had no kick start Pedal. The engine has sat in my basement for several years untouched. I want to test the compression. How can I roll the motor over By hand?
Thanks. Jim

Take the magneto cover off I think it's 17 mm but you'll never spend it over fast enough to get a compression check.
