The other day I noticed my bike was ideling a little low so I went to bring it up some via the idle screw. Well as I was turning it and getting no response it came off. Im having trouble getting it back on because I dont know where it screws into.

 

Did you get this fixed up? If not, it screws into carb #3, in between 3 and 4. You should also have a small spring and flat washer

 

I haven't gotten it fixed yet and I think I found where it screws in but there was no spring or Flat washer

 

You will need to get those so it holds the proper tension and doesn't back out again. Some people say you don't need it, but I am of the mindset that you do.

 

My bike seems to not be very fast and could that be part of the reason that the idling is off

 

It absolutely can be the issue. Your idle will be off without it.

 

yeah the bike feels like it has no pull. I used to have a ninja 900. i know i cannot compare the 2 but i would expect this 600f4 to have some *****. It wont even stand up on it own power

 

It should be able to do that with no issue and then some. I would fix the Idle screw thing and then move on from there.
