I'm running an early panhead pump on my 1947 FL. The difference between this pump and the correct knucklehead pump is the larger feed gears used in the panhead unit. My question is if anyone is using the panhead pump in a knucklehead and if so, does the increased oil flow supplied by the larger gears cause over oiling?
Also, in the 1960's and 70's it was common practice to remove the oil pump governor/rotor from the end housing. While I'm still running mine, I don't remember the logic as to why these assemblies were generally not used - we just took them out because they "caused more problems than they're worth". Being older and (hopefully) wiser now this sounds like a chopper motor mechanic's blatant proclamation or other myth and I'm wondering if there's any validity or substance to it. When I built this motor I included the rotor thinking hat it was used for a long time throughout the 1940's and apparently worked and thus far, it hasn't appeared to have caused any top end over- or under-oiling problems. Does anyone remember why this was done??
Thanks...
