    Actually from the older dyno runs it didn't really lower the peak hp much, only about 300 rpm or so below the 8600 rpm that Kawaski had, but it actually increased hp for Marcelino to about 25 hp. The best part was it boosted the torque through out the entire power range. More power where you used it.

    I have the instructions in a google document. Click here

    I have been eyeing the MCm mod and already picked up an FMF core 4 (used) for it. I want to get it running stock first. Then get the header pipe and jet kit to play with the power. first to get it running.
    KLXster gave me some great advice, but I work nights and need a couple of days off after 4 nights in a row. Before I can get In The garage.

    He knows his stuff with the CV and the pipe... and makes sure you never forget the does. Or that he's "expert" in about anything else he knows. :lol3
