hi, by the way thanx for all the info on my last thread. i noticed after an oil change that there is a leak on the left side of the motor, i cant be sure but i think its leaking from the gear shifting kick lever. i notice that the seal is pulled a millimeter away from the lever. isnt it supposed to be tight around the lever shaft going into the motor? do i have to crack the case to replace it? and i think i have a crank seal leak would that cause run-ability problems and do i have to crack the case for that? again thanx for all the info.
