From the picture which is light enough to see anything just about it's missing the air intake tubes (these don't do anything just hide wires) the side inspection panel is missing, end can looks as though it's been chopped off so he's probably sold it as they go for a good price on eBay £80+ for an arrow end can. The screen is missing in one picture as well which suggests some sort of frontal impact which means there could be a whole heap of problems. Personally I'd steer clear of it, 2 strokes are like women you have to treat them well and buy expensive things to keep them happy, if you don't they can be unpredictable and very stubborn. Basically if you want a 2 stroke spend more money on one, a decent one will go for between £1500-£2000 now a days.
