You have to look past the bling on this one, it is listed as a project. Wiring looks to have wrong bullets and has been messed about with, no seat in the picture, carbs ? You can see that all the chrome bolts are pitted on the bolts. Don't know if the tank is lined.
I would not bid on a bike like this until I have seen it up close and personal and it would have to be cheap.
These 250 engines had cam and cam chain problems
