I have a 04 wolverine and would like to gain alittle more power,but it runs great.should I leave well enough alone or mess with a good thing.I am thinking of trying the stage 1 power kit which includes a KN filter and jets, will doing just that,do you think there will be any noticeable gains?
I am not new to working on motors but new to messing with carbs
What do all of you think?

 

I would get a pipe and silencer also with the stage one kit and then you should notice a pretty big gain.
