So I installed an untested CB550 engine into my bike. I hooked the clutch cable up and made the necessary adjustments. Well I can't shift. I don't think I can seperate the clutch plates any more than I am as the adjusters are maxed out. The transmission stays locked in gear even with the clutch pulled in. What's the deal. Have any of you experienced this? Am I missing something totally obvious? Thanks for any help.
