has any owners of the SCORPA 250 F, had to adjust the valve shims yet?
just like to know how long they last? before adjustment is required.

The valve shims will not wear out if that is what you are asking. The valve clearance will change periodically due to valve/valve seat wear and the shims will need to be changed to maintain the proper valve clearance.
