FE/FC 2016 FE350 Idle adjust

[Joe Piddington]

Just getting ready to start breaking in my new bike finally and it seems to be idling high....any idea how many clicks it should be at. If I turn knob clockwise until it stops- how many counterclockwise turns back to proper setting. I didn't even count clicks yet it just seems to be on higher side

You should install hour meter and tach then you always know rpm at idle.

Ok def good idea and will do, but what's the stock idle setting?

I don't know if this would help you, because I do not know, but if I had to guess I'd say somewhere north of 1800rpms.

idle speed confession: I just go by ear, to where the bike sounds "happy" when it's idling. If you don't have a tach, give it a try. Also, IMNSHO, a slightly higher idle is better than one that is a bit low. I worry about oil and coolant flow on a 4t.

good luck.

Thanks!!!

And another tip, don't set it too hard or they don't start. If too high it's like holding the throttle open and it won't go.
Came across that a few times by now as they increase a bit when loosening up and suddenly hard to start, people go panic.
Just turn it down a bit and all good.

Mine seemed like way to high of an idle when it was new, to the point i almost could ride it without giving it any additional throttle. I broke it in like that then turned it down which made it hard to start, so now I'm somewhere in the middle. Has anyone else noticed slightly better throttle response off the bottle when they get there idle set at the sweet spot?

I remember them telling me something about adjusting the idle when I bought it. (Halls) I dont remember exactly what they said would happen but I do remember them saying you can mess something up if you move it too much either way. According to the manual it should idle at roughly 1900 RPM which does seem pretty high. It also says in the manual the idle is not adjustable. I will see them at the next enduro and ask them again what they were talking about.

If it starts good and the idle sounds slightly high, I'd say it's perfect.

yep

Higher the better (with in reason) for single-track.

Correct! If it's too low it doesn't run right neither and it will develop a hesitation when the throttle gets cracked open.
They shouldn't run too low anyway as it's a really short stroke oversquare engine.

Reason for the odd throttle response is that the TPS becomes out of range. Normally when the idle needs a big adjust the bike needs to be connected to the diagnostic tool to reset the TPS also.
After the idle is set correctly the TPS range is then reset so the 0 to 100% span is inline with the new value. It runs smooth as after that.

Yea I was wondering about the idle as well after the break in period if it would sound better and I am going to throw the rekluse on and I don't want it stalling coming out of a turn.....thanks for all the feedback****************************************


Did you guys change you're rear sprocket or keep the oem supersprox????

Thanks
