Got a banshee that was sitting a while..still sitting..and im going to rebuild it...what is the best way to get all the old dirt and other stuff like oil off the carbs. and legit products out to remove it all. Also paint has chipped away from the crank case cover and other things as well. is the best thing to do just have them powder coated, or just replace the cover. Lastly, the engine just does not have the shine to it any more..lots of oxidation on the out side of the engine..can i get that powdercoated or am i just screwed
