Can anyone tell me the outside diameter of bantam piston pins?
D5, D7, D10, and D14....Are they all the same?
Thanks much.

The lack of response to your question is probably because folk on here are not using BSA pistons however the info is about on the internet. I found this D14 manual -

The smallend of the 125 and 150 models are definately 15/32" and I believe all the 175s are all 9/16"

the manual above gives the pin dimension as 0.5617 to 0.5620

Hope that helps
