So I finally got this thing back together with all new bearings in the differential and axle. Pretty sure my magneto is going out because my lights are very dim even at higher rpms and battery isn't recharging, and it was replaced a couple of months ago. Starts and runs great, until it starts to warm up. That's when I begin to.lose throttle response, as it cuts in and out. Thoughts? Haven't really dug into it a lot yet, but plan on tackling it over the next couple of days.
