Hey guys. So i have a bbf 460 and i want to check and adjust the timing. Im watching videos on youtube and most suggest the adjustment be done at 4000 rpm. How are you guys checking timing. I made a Y connection to deliver water to the motor and pump off the hose but my temp got too high. Ill be trying again with a new Y that has valve controls so i can deliver more water to the motor and just enough to the jet pump. Can i adjust the timing at idle ?
