I finally got her gassed up and went for a ride. It seems really slow. Like it has no low end. Maybe because of the smaller 36 tooth sprocket. I don't know. Could just be the cheapo engine. It barely makes it up the hill at full throttle. It does make it up the hill though. May need a carb adjustment. I'm gonna do an exhaust change soon too. I have another one of those cheap expansion pipes like I put on the other bike. That one gained some low end when I changed pipes, so we will see.
I have a 52 sprocket on mine and it will now churn up the steepest hills with just a little help at the top. Of course the top speed is only around 25mph or 40 kmh, fast enough in rough, winding, hilly country.
