    I have a 450r radiator stuffed in mine and I dont care for it. No scoops and it is close to the head pipe.

    im in the middle of mounting a stock 450 rad and oil cooler onto my 400 frame with a 450 motor. Head pipe does come close,i might wrap it. im goign to cut the factory rad and oil cooler brackets off the 450r frame and weld them to the 400.

    A little off topic,but what did you guys do with the stock 400 fuel tank the make clearence from it hitting the top of the 450 motor?

    The 400 tank sits on the frame rails but now with the taller 450 motor its sititng on the motor.
