This is so cool.  This is a link to Engine's Only.  Check out the dyno's.  I'm sticking to my Crf150F w/ Engine mods from Engine's Only.  Compare to the new CRF150R.  Look at the 9,000 RPM mark.  The "R" shows great power!  It just keeps going to the moon.  Up to 9,000 rpm's, however, it looks like my "F" and hang with the new "R." 

 

Actually, I'm just pointing this out because I'm hoping it makes me feel better for keeping the "F."  That's a joke folks.
