    Will A Primer Kit Lean Out the Motor?

    Iam interested in installing a primer kit on my 99 gp1200 cuz its a bear to get started. Iam wondering if anyone has any input or experience with theirs. Is re-jetting needed? Also do the carbs need to be removed to install the primer kit? Thanks

    no, its will not lean out the motor

    yes, you can do it with the carbs installed, on a GP

    should consider blocking off the oil injection also while in there

    In order to install a primer kit you have to remove the choke plates. This requires grinding the back of the screw as it is deformed to keep it from backing out. You can also drill it them out, either way I prefer to have them on the bench to insure no debris gets in my motor.

    Going premix is also an excellent insurance policy. On these older GP's the oil injection comes into the airbox right above the carbs.
