jetting specs for 99 spx
It's been a while since I played with 2 strokes..
What would be ballpark jetting specs on a 787 motor with a spec2, stock head @ 140 - 150psi 46 novi, looking to get 7500 rpm. I'm guessing a 17/22 or 16/24 swirl or a concord 15/23 will be the prop of choice through stock nozzles.
If it were the same carbs as my GSX i'd be ok..
