Hey guys. Love this site and it provides some great reading.
I have secured a clean titled "1965" Panhead that has a motor with STD cases & S&S jugs. The seller thinks it is a Stroker, but he is the third owner so we cant trace anything back easily.
I have been in contact with the new owners of STD who have been less than helpful trying to ID the motor using the number stamped on the cases.
Is there any way of telling (without stripping it down) actually whats inside or what the cases are?
From what i have found the STD gear was pretty high quality stuff when it was in business.
Anyway, any help or light shed, would be greatly appreciated.

Thanks to all.

remove spark plugs and remove timing plug on left side , get some one to slowly crank kicker over while shining a torch in the timing hole and see what markings turn up on the flywheels.

S+S site has the flywheel serial codes , it might tell you what youve got

Hi mate welcome and congrats on the purchase. You have is a set of STD cases, how would they know what motor was built around them? That might explain their attitude?


How about some pics of the bike mate? Pans rule but Im biased

Thanks for the reply Pete,
I had in my mind that if they were "notched" they may be stroker cases, or if they were overbored they may be "big bore" cases. I would have liked to know.

The other thing i wanted to know from them is when they were made.

I did contact the new owners and they weren't interested in helping.

PS: The bike is on its way to Long Beach for a slow boat to Sydney!!!!
