i have a 05 636 the bikes runs fine but while idleing it runs rough pls help

 

1. check your spark plugs
2. make sure all 4 are firing correctly
3. check fuel lines for clogs
4. check fuel pump(make sure it is giving the right psi 40ish but check your manual)
5. make sure your idle is set correctly

now does it start rough on cold starts??? (meaning when you first turn the bike on for the day)

does it steady out after awhile or does it take you to ride it for awhile to get rid of the roughness??? meaning when you idle it is rough...if you run it for awhile and come to a stop sign and let it idle is it still rough???

 

thanks for the info im going riding today so ill keep an eye on what you said and to see if it smooth out. But whenI first start the bike its fine then after a min or so its starts to idle low and rough

 

I have kinda the same issue on my 03 636 idles fine then starts to idle between 800 and 1200 back and forth jumping all around like its chugging

 

make sure that nothing is obstructing or hindering the fuel and air from getting to the engine...check air filter, fuel lines, air box, etc....

i know this is alot of stuff to check but it could be any number of these things....ohh one other thing if you have ever run out of gas on your bike or you just bought it used or something might want to make sure that the fuel pump is working correctly and not failing under pressure...meaning it isn't giving off enough fuel line psi....

if you cannot check it you can have your local bike shop check it with a machine...

 

Reach down and adjust the idle. Give it a half turn or so. If it's still running rough. Runn some injector cleaner through it. If it still does fix the problem then I would say take it to the shop.

 

you are running atleast 91 octane right?
