What jet should i buy for my grizzly 660 and wat will i get with rejetting the carb just top end or low end as well? Thanks

 

jetting your carb is to restore the air/fuel mixture to a correct ratio due to drastic modifications to the intake,and/or exaust,,,,it is also used to restore the mixture due to a drastic change in elevation

 

so if i was gonna change a jet in my carb i wouldnt gain any performance? Wouldnt it be the same as if i was gonna buy the dyno jet kit?

 

if you were to change the jet in your carb,without adding engine mods that would change the air flow/intake,your engine would either run rich,or lean which ever way you went

if you bought a bike that was jetted to run at sea level,and you moved to 5000 feet above sea level,you would also have to rejet,because the higher in altitude,the leaner the air is

"Dyno Jet" is just a brand name of after market jet kits
