Ebay item 330037292054 - some yoof who's stuck a Yamaha RXS engine in an RD50. Just the engine, mind. He hasn't got it plumbed in, and the picture of him trying to fettle it is a scream. The best bit is the last line in the description: "i have checked everything on the bike that needs to be m.o.t werthy and engine will pass and dont need indorcators as its old i no becouse i used to work for a motorcycle shop" I'm so tempted to ring him up and ask all sorts of daffy questions...
