http://cbrzone.com/cranksrods.htmlAPE introduces our dummy counterbalancer shaft for the CBR1000 2008 and later. This shafts replaces the oem shaft when removing the counterbalancer on on motors with race balanced crankshafts.
It blocks off all oil holes. Removing the counterbalancer assembly frees up horsepower. However, we do not recommend doing that if the crankshaft has not been race balanced. APE does this, and it includes fluting the rod journal oil holes and micro polishing'
