the honda mv is pretty cool for the psf. i also have some other units to test mv configurations. they're from earlier yz125/250. i got them before the 14's came out, to test with the kx450's. finished the 14 honda this week. we're testing this weekend. there are some other designs for the psf mv out. the other, is a pro circuit unit. it's aluminum, and it does not have a recess in the comp side.
