I don't know why anyone would want a Honda engine on a Stander, or any other larger ZTR. Honda's larger HP engines are generally nothing but troublesome and expensive to fix. The smaller Hondas, say less than 10HP, are great engines. The engines up in the 20hP or larger range, are nothing but trouble on a constant basis.
There is a reason you do not see many of the larger commercial ZTR's equiped with Honda engines. There is also a reason why the companies that have offered Honda engines on the bigger ZTR's quit offering them in a rather short time. Think about that for a while.
