i just rebuilt my bottom end of my 93 900rr got it back up and running but am leaking coolant from oil cooler my question is is the o-ring thats on it pretty standard as far as the size?meaning can i get one from another bike or is there any other ways to fix or replace it my dilema is the shop is closed today and i wanna get it fixed like yesterday

 

I think they are pretty standard. The one on my '93 F2 is a 50x2.5 o-ring. That's the same size as the o-ring on the front of the engine block on the 900RR, I think.

You can always try one of those 'gasket in a tube' options where you basically make the gasket you need...
