It should not idle that fast anyhow. Normal idle is 750 RPM

are you reading your rpms right....5-6000 rpms should equal 70- 85 mph....that is certainly not idle speed....invest 20bucks in a Haynes manual----it is good reading

Absolute rubbish!! The idle speed should be between 1250 and 1350 rpm. If the engine is cold, the EFi will raise the idle speed temporarily to about 1600 rpm until it warms up (usually within 5 to 10 minutes at a standstill).

Your idle speed of 1120 to 1200 rpm is absolutely fine. However, if it drops any lower, you can raise the rpm by playing with the idle speed adjuster screw located on the gear-side under the fuel tank (can be seen without having to remove the fuel tank). Turn clockwise to increase rpm. You will find details on how to do this by selecting your manual from this link:

WARNING: if the idle rpm continues to drop, you may have a more serious issue with the valve clearances, air-filter, or spark plugs. Consult a technical book (such as Haynes), or take it to your local Yamaha dealer to get it serviced.

depending on the motor, all makes and models should ranged no less then 500 rpm and 1500 rpm, the most common idle is about 1000 rpm and 1200rpm.
