Product Reviews


  Installation was elementary. Once the filters were installed, I left them in place when removing the carburetors for rejetting. Tuning the carburetors was straight forward and the performance increase is very noticable, especially in the mid-range. Had I known how easy this was and how much difference it would make, I would have tossed the stock airbox in the bin the first day I brought my bike home.
