HELP!!! need piston

['alljackedup']

I recently blew a piston in my 318ccm Rotax Single banger its a 76mm bore, 70mm stoke, built in Austria. I have found out that motor came out of a 1969 Olypmique. Does anyone know somewhere there might be a motor like this kicking around, or any other single preferably 300cc or bigger. OR... where one might find a new piston? I also found out there is a guy in Winnipeg that has pistons, his name is gary and apparently he had alot of vintage engine parts, new and used. Does anyone know his number? I got a number but says its out of service. Any help would be appreciated. thanks

This guy will not have but if you can not find what you need locally send him an e-mail and he will likely know where you can go to get what you need.

Are you sure it has a 70mm stoke? If it's 76x70, it's probably the same piston from a 640 twin (if they even made a single banger with those dimensions).
A 69 Olympique 320 had a 76 bore and 66 stroke.
Any dealer can order you a brand new SPI piston kit from Sun & Snow, Kimpex, etc... Go here to download the Sun & Snow catalog.

Sun & Snow catalog shows only $55 for a brand new SPI piston kit for the 69 Olympique 320.

Did you even try going to a Ski-Doo dealer? The OEM piston still might be available.

Im looking into it right now. this motor is original not touched, the stamp says 76mm bore(i measured it) and 70 mm Stroke, 318ccm . the 300 uses the same piston, but with a 66mm stroke.( I have a shroud from one of those too) lol. thanks for the input, ill be on the phone shortly.
