Wanted - 175 Piston or Cylinder

[PJM]

Hello,

I am in need of a 64.5mm short style piston that fits the 1977 175 KTM motor with the 6 fin cylinder. Alternatively, I am in search of a 6 fin cylinder that fits this motor with a bore of 64mm or less. Does anyone have either of these or can recommend a source for me to contact?

Kind regards,
Pat

Hi Pat,

   Have you checked with Al Buehner his # (216) 651-6559.

   Good Luck, Lee

Hello Lee,

Yes, Al was checked.  He carries pistons up to 64 mm and has no 6 fin cylinders for the later model motors.

Thanks,
Pat

There is a .040 oversize piston on eBay, but doesn't include rings.
