Yeh i have and she screamed.It was out of a 83 yz 490 air cooled motor.Not very hard to do,just had to shim the motor i beleive to the sprocket side for chain allighnment.I also bought a 40mm carb for on it and ran the air filter out the back.Cuoldn't use the stock snorkle not enough room and had to use a zinger fuel tank up top.The exhaust was custom and had to cut a radiator shroud,another problem was the spark plug very tight to get in and out.That 490 was a tight fit in the 85 Z frame.I got pics somewhere.I'll try to post a pic.

Teaching quads a lesson
I was gonna do the same with a yz400 motor, but lack of space and money.

Dont belive they are, if your wondring if the 490 fits in the blaster, the blaster needs some major stretching to fit from what i have seen.
