Your cr is lookin great,I know how cr,s photo if it,s cloudy or sunny the cr,s pic can look like a diff. bike. Ever try a icat ? They work great on a 04 cr125 e. valve motor, icat works good on a 06 cr125 also, bigger improvement on the 04 tho. I just did a google and found a mxa article, stating how the icat improved every part of the 04,s 125,s powerband, then icat said it did nothing for the RM125. I would think the icat would work, on a e.valve cr250.
