Due to growing demand, we've just purchased a new purpose-built crank shaft machine. Reduces chances of cracking by polishing the journal radiases. Oil has less chance to cling onto the crankshaft. This increases the windage affect and increases horsepower. No time wasted hand-finishing oil journal radiases. Crank surface is stress-relieved. Approximately only 2 microns removed in process (dependent on shaft material). Less friction and heat generated on bearing journals. Custom cycles available for individual applications.
