I just went 1 tooth down in the front .My idle seems to be to high.
Its at about 2000 rpms. What should it be?

 

2000 is a bit high but has nothing to do with your sprocket selection. Don't have an F4i manual handy but I'd suspect the idle should be between 1200 and 1500 rpms.

 

Idle speed for the F4i is 1300 +/- 100 RPM at normal operating temperature

 

I idle arround 1150

 

I'm the same around the 1100 +/- RPM.
This would be when the bike has warmed up so around the 50 degree's mark.

anyones RPM's jump around a little bit after completely warmed up to about 180-200 degrees. Mine go from 1350 to abotu 1800 when jumping around. only when stoped at taffic lights or somthing is when I noticed. Is this normal? thanks for your help.

 

it shouldn't be "jumping arround" I can see a slight difference here and there but not 500-600 rpms. I would turn it down some the idle adjust is on the left side its a black plastic valve, no tools needed.

 

Its not really jumping around quick, but when i stop at a light after riding for like an hour it tends to idle at 1900, then sometimes at 1350 where it normally is

 

could be your throttle cable needs some lube then.

 

I have just lubed it up not even a month ago, both throttle cables...real good!
