DaVincini makes a booster venturi for the S&S that replaces the main nozzle of S&S etc. (not for Linkert AFAIK), but it's not in the right place. Apparently, it still works.
The M-53 body is machined differently internally for the special venturi, the M-53 booster will not fit any other 1-1/2" Linkert "normal" carburetors: M-25, 36, 45, 61, 74, 75.
It looks like a Holley 4150 booster (smaller than the M-53) or Holley 4010 booster (larger than the M-53) can be adapted to the common Linkert (again, not the right place, but still useful), but no known results. I have some additional comments in my booklet.
