Thanks for the video. Do you have a video for the Hisun 196cc build? My grandson bought one and I'd like to do exactly the same thing to it you did but I'm brand new to these 4 strokes.
Yeah the 5:1 gearing against a 19 inch tire is not good. Even with a torque converter. Once the belt shifts you're getting less than 5:1 gearing and RPM stays low.
