I'll be interested to see what grizz1 has to say after he's run in the GX II and run it back to back against the MG66 in his 808..Personally I just can't see it being anything to tempt me to change motors.It would have to be a LOT better than the MG for me to swop.The MG is just so easy to drive.Bottom end grunt without the need for late engaging clutch..and top end forever..plus 11m30+ run times and that's with a 7mm venturi.I like the linear delivery too..none of that late surge the 7 ports give..just smooth all the way through the range.Enough to wheelie my 808 but with little or no wheelspin (well unless I want to mess around)I suspect the toro-nero's for example might give a fraction more overall power but that's no use if you can't get it onto the ground.
Let's hassle for a new style head/button in black n red though..
