Hello,
I've always loved these bikes and finally found a 1975 cb750 I'm working to get running by summer. I will probably be looking on here a fair bit the next few months trying to figure this thing out. The bike looks amazing and had been garage stored since the mid 80s.
My first problem is the engine is seized. I thought I'd remove the plugs and put some penetrating fluids in to help break it free.
I was able to remove the outer 2 plugs. They were 5/8s and came right out. The inner 2 plugs are 18mm and stuck so I'm assuming they were also stuck 30 years ago or the plugs would all match.
Any tips on getting these out? I've put a lot of force on them but held back as I don't want to snap them off.
Thanks
