sleeper06 Posted March 25, 2010 Report Share Posted March 25, 2010 With a 2.36 ratio primary drive I ran 16/39 and 17/39 in the 1/4.With the 16 I actually gained mph on the big end.Stock ratio primary I have seen all sorts of nonsense,but most ran 17/18 and 40 in back.You will also need to see what your motor will pull,its very easy to over gear Quote Link to comment Share on other sites More sharing options...
