So guys I've read and read on here and still havn't cleared up what exactly you can and can't do with the command singles. If someone has a link to a thread that would help that would be cool. I know the stock briggs rods won't take high rpms, but what about the kohler? We pulled a k241 10 hp for years with a stock rod and bearing insert and regularly turned it past 8500 rpms with no problem. I'm really not a briggs fan and kohlers have always been better carburated and manufactured in my opinion. I have both and I'm leaning toward just using the briggs 31 cube ohv, but I don't want too. I know midwest has some stuff for the v-twins, but I havn't called about the singles. Any help would be appreciated.
