2014 S40 Boulevard idle adjust
09/17/14 at 08:30:36
 
Hi all,  I had some dumb sob sitting on my bike and he f' with the idle adjustment really bad.  What is the procedure to reset my S40 to the proper idle?   I have searched but most info seems to be regarding the fuel mix.  Do I clockwise close my idle screw then back out how many complete turns?  help please, I don't want to pay a dealer $100 for 5 min of work.

The idle speed is adjusted with the knurled screw on the left side of the bike (near the choke knob)... (you can turn it with your fingers, no tools needed)...
Turn it CW to raise idle... CCW to lower it...
Turn it in/CW until it sounds like it did before...
A little high is better than too low... Too low will not oil the cam properly, and will cause premature death of your engine...

Idle should sound even and smooth (putt,putt putt)... (more like a lawn mower, or your car)... 1000 to 1100 rpm...
Not lopey and stumbly like so many Harleys sound...

It should be able to run about 6 or 7mph in first gear with no throttle...


PS.. a dealer might just set it for you by ear in the parking lot for free if you ask...  (shouldn't take them 10 seconds)...

+1.  Mine has a variety of idle speeds depending on engine temp. Roll Eyes

That's the second time in a month that we've heard of someone messing with someone else's bike. What's with people these days? Is the guy still breathing?

There's no problem that a full tank of gas and a sunny day can't fix!

I put a, 'shim', between the idle screw, and the stop.
Attached it to a strong, 'string'.

When I start, (engine off), I just twist the throttle,
put in the shim, let go,  Then start.
(I am their anyway, turn the gas on, turn the key on)
(Raptor Petcock)
By the time I get the helmet on, Jacket on.
It's running at a high idle. Then just coast down the drive,
(200 yards). Then when I hit the tar, accelerator opens,
and the shim just falls out, and hangs their.

Two reasons I do it this way.
1. Idle is  COMPLETELY  Different from a, Warm engine/Cold engine.
So I have my screw set at, what is about 1050 RPM, at a stoplight.
  When Engine is  WARMED  Up.
2. I guess I am old school. and believe, 'Just' pulling the choke out,
(which will raise the idle),  ALSO, Pores  More gas, at a time when the engine does Not need it.  (Choke= changing the amount of Gas into the engine, with out changing the Air amount)

(I suppose this comes from my experiences, of, 'older', ICE's, having a,
"Choke", and a, "Throttle" control).

Any way you want to do it. Adjust Idle on a, Thoroughly Warmed up engine. (To 1000+ RPM).   (More is better than less).  You want to get that Oil,  RIGHT NOW, to the top of the engine.
So use the Choke, or shim. Your choice.

Now on the V800, I am just lazy. I use the choke.
(That one has a Carb also)
And any other, 'modern' MC, would probably do the same.
(Unless it is, 'injected', and a computer attached)

BUT, even if you have, a 2015 S40, IT is  STILL,
a, 'old world' design.  (Which I would have never known, had it not been for the very knowledgeable folks here, who are willing to share their experiences).  So I use, 'old world', technique.

LOL, Grin  Some here have told me.
'Just Use  the Choke'.
My Answer simply is.  "Some do, some don't".
It is ALL  your  Choice !

The point is, Even that you have a, 'NEW' one.
You have  GOT to have those RPM's at 1000 + when you start.

Well, unless you want to trade it in next year or so. for something else !
