F115 2003 low idle

[<John>]

My F115 model 2003 has very low idle speed when warm. It idles at about 500-600 rpm but according to manual it should be 800-900 rpm. Due to the low idle it often cuts out when shifting in gear.

Since it has electronic injection there is no way of adjusting the idle speed.

The engine has 80 hours on the clock. Any ideas what is the cause?

The idle speed on a F115 should be 750 plus or minus 50 RPM'S in neutral and 700 plus or minus 50 RPM'S in gear. The idle speed can be adjusted by a Yamaha dealer
