'82 250MC Ring
« on: November 23, 2016, 09:09:07 PM »
Hi All,

Can anyone suggest a source for or an alternative to a piston ring - standard bore - for my 250? They seem to be unobtainable now.



Cheers, Paul

I was also chasing a single ring for a 250 piston, but 71.5mm. No luck. I think they are 1.25mm thick for the single ring elko piston.
A 71.25mm ring was available from Al Beuhner in the states. Give him a try.

Else your only option is a new 71mm piston, or just go the next oversize at 71.25mm. Both available on Al's website.

Have you tried Bert Floods ? They have ELKO piston and rings. Just bought a ring set for an 84mm piston. Top ring is the "L" shape you describe (not sure on the correct term.) Be sure to be sitting down when getting a quote on a piston...
