I just got my hands on a 1987 banshee bored 40 over with a new hot rods crank and wisico piston kit, and tooney pipes, I got this (Not running), for 500.00. i think it was a good deal.. This bike is straight as an arrow, in great shape the stock bumper doesn't even have any dents, any ways as for my question. This thing has sat in a garage for about 5 years now and the white plastic has turned a little yellow, i was wondering if there is anything i can do, short of buying new plastic, to get this thing looking good again. by the way i cleaned the carbs drained the tank, added new fuel and she popped right off..... This is an awesome site...
