Ready for some upgrades. I am looking for some performance upgrades for this bike. I feel that the bike has a lot of power, but it also has a lot of weight, which equals, need for more horsepower. I donĀ“t want to spend a lot and I want to be able to do these upgrades with simple tools in the garage. Any suggestions? As for now, I have stock parts on the thing. The only enhancment that I have is the Two Brothers \
