i want to get more power out of my blaster and am wandering what size jet is best and what kind of filter is best

 

I started using a Uni-Filter, later changed to K&N, I felt it offered more reliable sealing and filtering. Both are good filters and will add some pep. You shouldn't have to rejet if all you change is the filter and have no other engine mods. Just check the plug after a short first ride. The most it'll need is to go up one or two sizes, from a 230 to a 240 main.

 

If you want more power jets are the way. Jets are what you do once you've give it more power!!! Try a new pipe. I put a new FMF fatty pipe w/ a power core 2 silencer on mine and my friend can't believe it's the same quad.
