Not tunable, it is rebuildable.. Reasonably priced from denniskirk.com. ($200 dollars) I bought it because really I didn't care how loud as I ride mostly on private property and wanted something that would bark when you would get on it and give me the most power for the buck. Added torque was felt down low and through out the mid range and I could pull a gear more up hills that I would have had to use more RPM's and a gear less to get up the same hill. I for sure buy again.
