Using this racing kart is straightforward. First, make sure you've added all the necessary parts that aren't included like wheels and hubs. Before each use, check the Mychron 5 2T gauge to ensure everything is in good working order. When it comes to maintenance, keep the Comet KA100 engine well - lubricated and clean the EGT bung sensor regularly. Since it's a used kart, pay extra attention to any signs of wear and tear. For shipping, be aware that the cost might be more than estimated, so plan your budget accordingly. And if you choose to pick it up at Comet, arrange for proper transportation to get it safely to your location.
