only if you cut or change the piston to clear the valves, also i think the compression would be low. if you want bang for the buck slap on a 143 stockhead kit and call it a day. and that would be less than half the price of just a +R head.

A + R motor is WAY too much power for her unless she is a FAST rider.



Put a bore kit of your choice, a 26 mm carb/breather kit, and a pipe.



When she can ride it full throttle, then upgrade to a + R head.

I would do that to. I would just slap a carb and motoHP 150 on it.

Nothing against them but a 143 is much better option in this case than a 150. The 150 is more apt to break an output shaft and unless she is a really fast rider a 143 will be plenty.
