Idle setting

Did a little searching but didn't find a thread that matched what I'm wondering.

The manual says idle speed should be 1100 RPMs +/- 50. Do our experts here agree with that? Saw in one thread where someone said to set it at 1200. Another person in another thread said they were running at about 800. What's the consensus here?

1100 to 1200 is good. I like to set mine slower, but that is me.

Throw the tach away. Set it by ear while the engine is warm. Check the throttle response from engine idle speed. You never no if the factory tach is correct or close.

A bit slower, and it sounds cammy, lopey. A bit faster it sounds smoother, circulates coolant a little better. I'd agree with Chuck's statement about throttle response. I was settling around 1100-1150rpm. But I like the cammy sound, so if it's not stalling, I'll slow it down when I start riding.

People bring me cars complaining about very minor hiccups at idle that can't be cured. I just tell them it's not designed to run good at idle, or idle very long, it's designed to be driven.

After the mods I've done, my bike likes 1100 to 1200 RPMS. Be leery of brining the RPMs too low. The oil pump isn't designed to operate efficiently at low RPMs. Not enough oil flow and you're asking for premature engine wear.

I only understand what I don't understand.

Very good points, well taken, to heck with the stylin' cammy idle.

Blaz, was yours idling that fast in the video? Sounded cammy, lol. If open pipes do that for you, I may switch some day.

I think she was idling a bit low. I need to get another vid up with the new mods installed.

I've played around with the idle on my bike a little. Slowed her down to 500-600 and she sounded sweat with the little lope. The only thing is that since our bikes are so high revving it hurt the response time and make her run a little off. I've got her speed back up to 1k where she was when I it her.

Keep her rubber side down.
