Can anyone on this site direct me to where I might find the original spec for engine valves for an R57/R63 the parts catalog shows both valves intake and exhaust as the same for both models, my main concern is the overall length.

Jef,
I do not have a valve handy to measure, but I can tell you that the valve (M 59 D 111) is the same for the R57, R63, R16 and R17. That might help others who have a valve out of one of their motorcycles to measure it!
Best,
James
