E12373 Crankshaft centre seal for 2T 3T 4T motors VITON UPGRADE

A must for anyone building a twin motor. All twins that have stood need a new centre seal, and even motors that have had a seal in may now be vunarable with the situation with ethanol in fuel. Future proof your motor by fitting one of these. 

If you struggle to fit the seal your self, we can rebuild twin cranks while you wait.
