I can bleed front and back brakes in less than 5 minutes. All you need is a Mityvac. They're about $40 from an auto parts store. It's an invaluable tool. Why dick around with gravity bleeding when you can use a pump?
I will vouch for these motors. I have been running with them all year and they are consistent and in great shape. They have been well taken care of and will be a great addition to anyone's bike.
He is just wanting to go to a big DM motor like mine.
