Hayabusa Dummy ShaftGSXR1000 Dummy ShaftZX14 Dummy Shaft

When you remove the counterbalance gear from a crankshaft there's no point in keeping the heavy counterbalancer mechanism in the crankcase. You can replace the entire balancer assembly with this lightweight billet aluminum "dummy" shaft. Remove the stock assembly and insert this shaft in its place. The shaft and o-rings block all oil passages.
