Post by: jimg1au on November 28, 2013, 02:46:50 pm

hi
which would you guys think would be the better motor for dirttrack
piston port 1975 cr250m2 honda
or 1977 bultaco reed valve 250
the bully in my book is just ahead because of right hand gear change
or i would swap my champion cr250 complete roller for a bultaco champion or astro short track roller

If the bully is a #195 I'd cream my pants and stick with it.
