What jet sizes did you use and anything other than the jetting done to the carb?
I am pretty sure I used a 46. I used the 170 as well. and nothing else.
I will say that after my first long country ride this past Sunday, the highway mileage seems to be good, before the upgrade, 45 city/ 60 highway, after upgrade 37 city/ 58 highway. not too shabby.
