I have a 96 polaris magnum 425 and i am looking to gain some power. I seen where people said if you jet you carb that it will have a nice power gain but what else can i do to gain some power? What performance will a epi sport utility clutch kit add? When i jet the carb do i need a 500 carb or keep my 425 carb?

Also should i go with mega mayhems in a 27 or zillas in a 27
