Full Version: Start up idle / procedure?

All I have done so far is start it. I know doesn't seem right-weather and work not conducive. I only let it run for a minute or so. It was running at 1500rpm. Like a sewing machine! .

I think I read in the idle thread that the bike idles at 1500rpm till it gets warm and then settles back down to the 1000 +- 100.

Am I right?

So what is the recommended procedure? Start and go? Start and let it warm up then go? I'm so used to choke/warm it up / then go.

when does the idle go back down to 1000 rpm usually?

I will get out on this thing Sat. no work and no rain. Yay!

thanks,

You're right about the fast idle on starting. Up here where it's generally cooler, the fast idle can last 5-6 minutes then settles down to about 1100 rpm. It depends on the outside temp.
I start and go, and I think most do. By the time I'm through some city stop signs and traffic lights (speed limit 30 mph) the engine is usually well warmed up by the time I get to open roads.
I think most riders don't bother with a warm-up. Just keep the rpm's down until there is some heat in the engine.
I start mine and let it run for a minute or two while I pull on my helmet and gloves. Being air cooled I don't like to let it run too long without air moving across the cylinder fins. Usually the idle drops to about 1200 by the time I snick it in gear and take off and ride slowly thru the neighborhood (25 mph zone and lots of deer) and the idle is normal 1050 by the time I get to the first stop sign 7/10 of a mile up the road.
+1 on Ferret's comments about 1050 idle after warm.

The Moto Guzzi required a ~1 minute warm-up for cold start to avoid stalling or slipping clutch.

The CB runs good from second #1.

I push start, ease out the clutch and nose it down the driveway.
Fast idle, no throttle is perfect for the 15 MPH zone on my street, before I leave the gate.
Then I ride it easy for a couple miles (oil warming up), moderate for a few miles, then hit the highway.
Mine maintains the high idle longer than any other modern bike I can recall, lasting maybe a couple of minutes or so. Eventually it settles in to its 1050-rpm hum, and that's that. I don't worry about riding her any specific way at start-up. I hit the ignition switch, put on my helmet and gloves, zip the sleeves over the gloves, and away I go. Often as not there is a parking lot or whatever to negotiate before hitting the street, so I suppose I usually do start off by going slowly, at low RPM. Rarely can I fire her up and simply rip away, right from the start, but when the opportunity presents itself I don't worry about it.
thanks. i think i got ir.
