I have a 2004 Rubi with Mud Lite 26's. I ride it in the mountains of southern middle tn quit often. It seems to lack low end power. What can I do to give me more low end power for climbing and mud? I am not a big fan of loud exhaust, but that is not out of the question.

 

Does it seem to run ok? no missing or bogging?

 

runs great. No missing or bogging at all. I double with it most of the time, when I have gone thru some mud or climb a decet size grade, it just doesn't seem as strong as it should.
