OK I figured it out! The one gear will work but this one will not unless you change other parts or what I think would be a minor modifications. Drill a hole may be a little more.

The ball cup where the drive shaft goes in that goes to the spur gear or slipper clutch is probably too small for the MT2. I am glade I did all this research as now I see how to put the MT2 slipper clutch in my MT Racer. Jbooker82 you did the right thing to cut down on any hassles. Bottom line in a way we all are right. Or you could look at it like I was wrong. Either way we know now!!!!!!!!!!!
