Honda help?

Picked up another Honda...72 SL 125. It needs a motor...About 3 months ago I bought a 65 CT90 off a guy I know and he said he had a SL that has been parked since 76 or so ...after looking for a motor with no luck I told him I would pass...So the other day he shows up at the shop and says..its in my if you want of course I take it. Im looking for a motor and or a good honda forum like this one. So I now have a 72 CT 70 72 SL 125 and 65 CT90.
