Adjusting Idle speed on EFI bike
« on: January 20, 2010, 05:19:22 AM »

Hi All,

I did a search and found this post: http://korider.com/index.php?topic=5949.msg56729#msg56729

Would the idle adjustment be similar for an efi bike? Or is it something that requires the dealer to plug the ecu in?

I haven't looked on my bike yet, but was hoping someone could tell me if all I'm looking for is a black knob as per the link or if I have to get my dealer to do it?

I'm planning on changing it to 1500rpm.. at the moment it kinda hovers around 1100 - 1350.

Also, do I change the idle after a good ride so its hot?

I dle speed is mapped in via the EFI, if it can be changed, and I think it might not be changeable, they would have to information, if you put in the new power commander available from Hyosung.biz or CCM Mechanics, I think I read that there are some idle and mixture adjustments that can be made with that unit, but the stock EFI is pretty closed up.

The knobs you are referring to are on the carb models.

What is your idle speed - it should be 1500 - 1800 rpm

I do not have a EFI Hyosung Bike, but the Throttle valve on most EFI engines has a "screw" that holds or limits the throttle plate (just like on a carburetor), I feel this will change the idle speed on the EFI engine  :o

My idle speed is 1500 rpm when I first start the bike from cold. Then drops to around 1300rpm.

Normally its fine, but when pushing it hard through twisties and come to a stop, the idle can drop to around 1krpm and cuts out. Then starts up fine.

Under normal usage it hangs around 1300 when warm.

I know my brothers efi 07 zx10r has a knob to adjust idle. So why wouldn't the hyo efi have a knob?

Krakum, do you have or have you worked on an efi hyo? If yes, then I'll take your word on it and go to the dealer. If you were taking an educated guess I might try my luck and rip the fairings off.

Mike, yes I've seen this screw in the efi service manual (which says nothing about adjusting idle :( ). It says not to use the screw to adjust the idle. Which has me confused.

From the service manual: "CAUTION
Never operate the idle screw ①  to avoid
variations of the carburetion setting."

I was told to not adjust that screw when I had issues on my EFI GV650, my issues turned out to be related to the tipover switch, they replaced it, and it has run fine ever since.  Mine would run for 10 to 15 minutes, and die and leave me stranded.

I have not tore into the adjustments on the Hyosung.  And from waht I was told, 1300 to 1000 rpm is normal warm idle for the efi bike.

I used to adjust my idle on the Harley through the fuel controller settings and mapping it against the USB prgrammer that was installed on my laptop, I am assuming that they do it the same way, but my guess is that Mike is likely right, he has way more Hypsperience that I do.  He is classicly spot on.

1300rpm is the correct warm idle for 650 engines

Not for the EFI

OK, I check the EFi service manual and 1,400 ~ 1,600 is the correct value.
