RTV Idle Speed

[SpudHauler]

I have a RTV1100 2009 and was wondering about the idle speed. The book calls for 1350 rpm and mine was 1400 rpm, so I adjusted it down to 1340 as that seemed close enough.

However, you see specs for the d1105 engine and the idle speed range anywhere from 800 rpm up to 1350.

Why such a big difference? And how low can you go before you start loosing valuable oil pressure and causing harm to your engine.

Hi.
You won't hurt the engine itself by idling it lower but you will vibrate the s@#t out of the machine! The three cylinder engine runs much smoother at 1350-4000 rpm, thats why Kubota set it there.

I have idled my 3 bangers down to 800 and they run quite smooth. Every engine is a little different so you need to find the sweet spot.
I prefer a slower idle speed than most.
One thing to consider is that if you have been working it hard it is a good idea to keep the idle speed up until the engine temps stabilize.
