I really hope so. I put them back on the same way they were on. Letters facing forward, numbers backwards.
You can just make it out in this photo.

Conrods should be installed with 'bearing key' facing forward - 'bearing key' is the bearing locating notches

I can't say for certain then. I put them on how they were but as I bought the replacement crank from DK maybe they had removed them and put them back on the other way around.
Guess that means I'll have to split the cases again.

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.
