[WORKSHOP] Building an NSU OSL 251 Racer
Posted: 8th January 2012 by ric@rocketri.de in UncategorizedI’m currently doing all the frame-work – converting an nsu zdb frame to osl – with plunger rear-end.
the engine will be 250cc, 4 valve, dohc, – and, hopefully it will be more fun riding, than building it:

Have a good look at this picture. This valve spring just wants to tell you how much luck you had for getting the spring out without having to pull smashed valves out of the piston.
