Why you changing the jet? Have you done other modifications? Have you done plug check?
Main Jet Size
What size main jet works best below 3000 ft? Mine had a 153.8 stock, I put the 155 in that came with the dyno-jet kit. Seems too rich now, no power! Might try the 150. Anyone have advice? Thanks

Trying for more power! Only other mod is tip on muffler.
Does anyone know what the stock jet size on the grizzly is?
