[jjdluz]

my 1992 yamaha 200 oil buzzer go off,and rpm drop to 1800rpm max,i belive it is safe mode,but i have been use premix for long time,and the oil hose have been plug,and last i check the oli in tank on engine is half full,i think i need to fill it up,also i unplug the wire from oil tank to cdi,didnt help,my tech meter said is oil alarm,so it shouldnt be over heating or water pump,right?is any wire i can cut so oil alarm wont come on again,thanks.

Re: oil buzzer go off and motor drop rpm

if your not using the oil ingection the cut the red wire at the engine float switch. if you run it unplugged the CDI will alarm you.
I would also remove the pump driveshaft as well.
