I know there are roller followers made for the Kohler twin.... how would the roller work with the stock cam? research suggests it might be worse without a cam specific for roller design. what cams are out there? everything I see is aimed at higher rpm ranges. my rpm must be kept below 4000, and 3800 is better because of my propellers (hovercraft)
I was planning on using a 27hp cam in my 25hp Command.
