1976 CB550F1 (what have I let myself in for) Project
philward:
If they had been messed with prior to you getting them, the people who messed with them would have had to have put all 4 rods on 180 degrees wrong as you say the letters were all facing forward - ie, all 4 are either all facing right way or all 4 all facing wrong way.
I have just done my 500 (that is I have just fitted barrel) and can't remember whether letters were forward or back facing - only that the letters were all facing the same way.
I would suspect the piston/barrel tolerances and take piston off and insert pistom/rings into the barrel off the rod to check for tightness - that will isolate the source of the tightness. You can check tolerances at this stage either way

Hang on. I've just found a photo from when i received the crank. I think I've messed up. This would be numbers forward wouldn't it?
It's been a long week.

Thanks for the help so far everyone.
Yes it span smoothly without resistance. I'll check end gap tomorrow and post the results.

The odd thing is the fact the outer pistons don't seem centered to the bores

Yeah, seriously regretting it now.
They were piston kits from DS, including the rings, pin and circlips.
