im on my buddies sn and i have a question about what shot is recomended. the zex wet kit comes with 55, 65,and 75 shot. i was thinking about puttin 65 but i would like to run a 75 if its not going to damage my engine or cause any other problems. im also going to run colder plugs and retard the ignition timing.

 

go with 55, the higher you go (on stock internals) the more likely you'll F something up
