Hodaka Piston Pin

[Joe Ormonde]

I finished a 1971 Super Rat Engine with a 52mm Webco Piston. No problem. BUT the Piston Pin was WAY too long. The 52mm Piston uses the standard 42mm Pin but the one in the Box is 45.75mm long. Is this Pin for the 125 Kit that Webco sold? I know that the 125 Webco Kit for the 93 Super Rat took a 12mm pin. Anyone know what this 45.75mm Pin fits? Joe

Can't say for that wrist pin, but the standard wrist pin on Hodaka 125's are 47mm long (but they are 15mm diameter).
I think your assumption that it could have been for a Webco 125 kit is as good a guess as any.
I sure it's not related, but I did see that a Vespa 110 had a wrist pin in that size range - 12mm x 46mm.
