I have a fully rebuilt SL350 K1 engine and a 1969 CB350 frame. From everything I read the engine should fit into the frame as easily as the CB engine. I've been wrestling with the engine/frame for about 2 hours now and have made almost no progress. I've got it sitting as it should be but I can't get more than 2 mounts to line up. Am I wasting my time trying to make these fit together or am I just going about it wrong?
