2003 450 FSE won't Idle ?

[wakeymatt]

Bikes cutting out when warm, any way I can adjust Idle or is it all controlled with the FI software ?

I haven't had to adjust mine, but I believe someone said it is behind the TBI red cover.

Man, your having a heck of a time with that bike. Start issues, throttle hanging up and now idle issues.

Haha tell me about it, i've thought about sending it off the scrapyard in the sky a few times for sure.
I'll have a look for this red cover thingy ?

You can bump up the idle but I've found the fuel lines deteriorate and the screen in the injector needs to be cleaned as well.
Just as a preventative measure, and no cost.

[wakeymatt]

I'll check the fule lines, is the screen easy to locate at the FI end ?
Also does anybody know how to adjust the idle ?

[stainless601]

The base idle can be changed by turning the brass colored screw on the throttle body. The screen is in the injector. Remove the tank, remove the fuel line to the injector. Look in the inlet port of the injector and clean that screen, if needed change the line. Hope this helps.

I located the brass screw however it really didn't make any difference to the idle ? Cleaned the injectors and fuel lines out, I take it the screen is not removable as it all seems fixed in but i've blasted it with jet cleaner both ways, so that should have cleared any blockages. Everything seemed clean with no fragments.
I've noticed that since I got a MCCT the bike will start and idle much better than before but as soon as I tighten the MCCT its will stop the starter from turning the bike over of the battery and also make the bike cut out at idle. The bike will also cut out at idle with the MCCT slacker when you come off the throttle. I could make a video to demonstrate if it would make things clearer ?

Check for erratic sensor readings (air and water temp) using the crappy software if you have it. if the readings are incorrect its probably a wiring issue.
You might want to make sure the valve clearances haven't closed up? That's a sure fire way of getting an rough idle

[wakeymatt]

No crappy software but took it to a garage a couple of times and they did software and valves for me.
The bike will idle fine but as soon as you give it some revs then pull off the gas it will die.
So the copper screw, does this adjust fule/air mix, anybody know for sure ?

Had an 02 FSE don't like to be negative, but burn the bitch.
Loving the 2013 EC300 though
