Ok forgive me if this is a medial question but i have to ask cos i simply dont know. What i do know is that when you want to cjange how the FJ idles there is a little switch u turn located sort of under the petrol tank. What I would like to know if you want the bike to idle lower in which direction do you turn it and how would you turn it once the engine is steaming hot? (im asking becos when i bought the bike the dealership had upped the idle so that the bike could start and idle while cold but the engine obviously doesnt stay cold forever and it is getting a little irritating having the bike idle at 3000 - 4000rpm after riding just a few miles which has made me have to leave the clutch constantly very open which isnt always a good idea) so yeah thats my story answers may be simple but please let me know I dont want to do the wrong thing and overheat the engine

To reduce the idle, you'll want to unscrew it, but it screws in an upwards direction.  I can't think of a good way to describe the direction, though.  Turn it one direction and if it idles higher, go the other way :)

Set it to 1100 or so, with the engine fully warm.

Thanks I will definitely try that when I go home this afternoon

counter clockwise to slow it down, , can be done with the engine hot if your carefull and have small hands, or wear a glove,
unless you ride bikes, I mean really ride bikes, then you just won't get it

84 Fj1100  effie , with mods
( 88 ) Fj 1200  fairly standard , + blue spots
84 Fj1100 absolutely stock standard, now more stock , fitted with Fj12 twin system , no rusted headers for this felicity jayne

most people use a long screwdriver and reach in from the right side...  it doesn't take much rotation to change the idle significantly.

"ditto" on the long screwdriver. Easy to adjust. Knob has notches it. Mine sounds better at 1100 rpm (trims out the rattling sound). Now if I could stop riding long enough to rebuild the carbs all would be great. I just keep enduring the slight rough running under 2800 rpm..... Enjoy the summer.

It is in the center of the 4 carbs on the bottom, no need to remove the gas tank. As everyone already said in (CW) is higher out (CCW) lower idle.

Long screwdriver keeps your hand from getting burned, as you probably want to adjust it when the Motor is warmed up.


When all you have is a hammer, everything looks like a nail.

Maybe you should just flip it over and reverse any directions already provided.....

Found it and tried but it will only work when the bike is warm otherwise turning it down and trying to start in the cold is impossible although I think the fuel I bought is also probably also partly to blame, but atleast when it was running and then I cahnged it down it worked, much better to idle at 3000 to 4000 rpm. I enjoy winter unfortunately but now I cant wait for summer

The dealership probably did that to avoid cleaning the carbs... sounds like the pilot jets are dirty and need a good cleaning.

How would I find those and clean them and would I be able to do it myself/ with the help of somebody who knows more than I do or would it be best to service it?

This thread (click me) tells and shows about everything you need to know.... You need to pull the carbs, it helps to remove the top 2 bolts holding the subframe to the frame and rotating the subframe down a bit.
