Title: roller cam for 25 twin
Post by: beezerboy on October 10, 2013, 11:42:54 PM
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.

At those rpm's the benefit of a roller cam would be minuscule. Keep the stock style and get a better profile.
