Title: 250cc 40 over rings needed for a weisco piston
Post by: ktmkirk on January 16, 2004, 10:47:34 PM
I am looking for a set of rings for a 40 over 250cc weisco piston for a Penton 250, I've tried all the local suppliers and this is a last resort before having to purchase a complete piston and ring kit.  Anybody have any rings?

Dr. 2stroke
40 over piston would be 0.040 over standard, and .040 is equal to one mm.  Hopefull this helps you out.

The Piston I have has a Weisco ring on the top and a Penton Ring on the bottom and the Penton ring does not fit right on the Weisco Piston, I really apreciate you taking the time to check this out...Kirk

i checked it again,and i found out,that the KTM /penton L ring(the upper one) fits perfectly! the lower ring can be ordered at wiseco, i think.upper L ring is 35$,if interested. regards Reinhard

Maybe someone out there has a used bottom Weisco ring. With a new top that should work?

KTMKIRK,
Please e-mail me directly and tell exact measurements of what you have and what you need and I will try to get an old racer to let me look through his "STUFF" and see what he has.  As Mike Lenz said even a used one on the following ring should work fine.
