Hey there, anybody familar with these YD scout's? I picked one up cheap because the PO couldn't keep the chain on. Was off when I got it. Has a tension arm with rollers to keep chain on that was all bent up and rollers shot. I straightened out the arm and ordered new rollers and chain and shimmed the sprocket over a little with some washers and got it going.
My question is seems to take a lot of "pedal" to get it rolling but then it goes fine. I put a new belt and rollers in. The tension rollers push the chain on the top and bottom maybe causing a little more friction than if the chain was just going straight from sprocket to sprocket. I am not familar with this setup but don't see any other way it could be mounted. Maybe the nature of the beast with only a 150cc motor and a heavy cart?
