Low oil horn goes off on 2004 Yamaha 250 HPDI
My problem is that the small oil reservoir on the port side of the engine will not fill to a level high enough to keep the warning hor from sounding and then the motor goes into the limited RPM mode. I then have to add oil manually to the engine reservoir in order to stop the horn and to proceed. It will go for about 20 miles befor I have to add mor oil to the engine mounted reservoir. There is plenty of oil in the main 2 gallon oil tank. I have noticed the cap on the engine mounted reservoir is cracked around the edges a little and was wondering if this could prevent the vacuum needed to fill it high enough to keep the sensor from sounding the alarm. My second problem is I also have not been able to get my fuel primer bulb to get hard even after I replaced it and the engine runs rough at higher RPM's. Could this be the problem. How do I get the primer bulb to prime and get hard. Any help on these two problems will be a great help. The fishing on Fort Peck has been awesome and I thought it might be something I could fix and not have to take to a repair place 300 miles away. Thanks
