Tired of twisting
crankshafts and looking for that 3rd hand to drive your
quad? This is for you. The "Flow-lock" is made by
Flowsystem racing. It is adjustable while you are
driving then locks down the engine where you want it, so
you can concentrate on driving instead of having your
hand on the engine lever all the time. This will work if
you have single or double tires and with any size drive
gear.
