    I guess I'll take that risk of kickback if I can get a little more performance. Just not sure how much to move it. Maybe just move it halfway and test it.

    I never got a chance to see if ESR plate on my bro-inlaws bike has any advance built in.
    I have heard by some that it does and others that it does not.
    I believe it does not and if you advnce it all the way you probably get 4-5 degrees without making the slots longer.
    On my cr500 w/2000 cr250 stator I have been able to slot it enough to get 8 degrees of advance
    On CR motors the clutch arm pushes against the side of the stator where the piece of metal on the right side is. If I advance any more than the arm will push out when pulling in the clutch.
    TRX motors don't need this arm stop so you can advance farther.
    i think i heard that ct had plates that are adjustable and esr's are not. someone correct me if i'm wrong

    has anyone done any more with the ignition curves. I just had my bike on the dyno(310 cc) and the dyno guy said it is in need or more ignition timing on the top end. Engine made max power at 8400 rpm. I am running the cr250 ignition curve. Maybe I just need to advance it up the the 8 degrees that was talked about in this thread.

    No added advance on the ESR mounting plates.

    Advance in 2 degree increments until close, 1 degree to fine tune.

    Start with the CR250R Timing curve, then try the CR125R Curve, and then for top performance develop your own curve.
