I need to adjust the idle down on my 2001 drifter , fuel injected. How do I do that?

Hey Big Foot,
You can adjust the idle speed with the small black knob in the attached photo.
Turn it clockwise to increase the idle speed and counter-clockwise to lower it.
Thanks for the reply. I have a 1998 Classic that has that knob. It has a carburetor. My 2001 Drifter is Fuel Injected and doesn't have the adjustment knob. How do you adjust the idle on a Fuel injection engine???
I too have just purchased a 2001 Drifter 1500. The idle knob should be in that position. If it is not on yours, it's possible that a previous owner moved it to a different place.
Thank you so much. I found it!!!

Some advice, FWIW, if you set the idle too low on these bikes, i.e. so that is sounds like a lumpy Harley, you'll have both cold and hot starting issues.
Thanks Bucko.
The R1 owner's manual says it should be 950 ±50 rpm, while the information on the next page says 800 ±50 rpm:

Which one is correct?
Is is there any difference between the J and R variants?
Thanks!

950 ±50 rpm is correct for J's and R's
