Yam 1999 Salt series II idle adjust

[mrom1234567]

When I put my throttle in neutral lock, and tap it forward to get the motor to idle at 7000 rpm like the other motor, it idles perfect.<br />If I snap it back to the idle position the motor idles at 5 then 4 then stalls.<br />Am I fooling myself to think that I can just adjust the set throttle screw?<br />Should I adjust the throttle cable linkage set screw?<br />If everyone here agrees it is probably the fuel pumps, I will definitely change them.<br />The fuel pumps are probably original to the 1999 motor. How often are these usually changed?<br />Thanks for everyones help in advance.<br />Michael

Readjusting the idle circuit may cure the problem. It is not unusual for them to vibrate out of position. It is also time to change the fuel pumps. I agree with Rodbolt on a three year cycle for them.
