I just finished "hopping up" my RS50, so I now have no need for the stock parts I took off. The bike the parts are off of is a 2002 RS50 with 550 miles on it. I've got the full pipe, cylinder, reeds, head, carb, front and rear sprockets. If anyone is interested, make me an offer. I'll send the stuff anywhere in the world, you pay for the shipping. Contact me at the email address below.
