this is what every drag racer road racer and hooligan has been waiting for, no more removing the worst 6 bolts on your bike to swap a trans, remove one plug and hold up shift pawl and remove trans..that simple, also can be used to vent the crank case though the passage between the oil tank and trans top, will come with gasket and vent plugged off. re uses your trans vent and buy the oil tank vent separately.. quick and easy trans changes at the track or home (DOES NOT COME WITH OIL TANK VENT PURCHASE SEPERATELY)
