anybody have any suggestions on getting more power out of my 2004 rancher 400 at. I have a HMF pipe,k&n filter, and jet kit installed from dennis kirk. I have installed itp mud lite tires. (not the deep lug) origanol rims. I love the size of the machine and don't want to upgrade to rincon. I want to maximize this unit any suggestions ????

 

Sounds like you have done the basic things. Now maybe lighter rims?
