hey guys,
i'm doing a complete rebuild on a 93' rm125 that i will be running in a non-current class.
my question is:
i ordered a piston kit from a local dealer and i thought it would be domed like the one i took out. i also ordered a moose high compression top end kit.
the piston she ordered is a flat top works style. the wiseco site says it needs head modifications. what exactly are the mod's it needs? will i still be able to use the top end kit?
i'm looking for more bottom out of this bike.
piston number is:
755m05400
2126cs
replaces 755ps
