This one above has a seat now & the engine/tranny is out of a Honda 110 ATC & has the high low feature. It's my favorite

The one above is geared too low right now & I need to swap out a sprocket on the rear miter box. Currently it will only do about 10 mph...but with the other sprocket I have, it tops out at about 30...plenty of power, it's a Chinese made clone of the Honda going 140cc's.
