Can someone shed some more light regarding the quote above? If you start counting from left to right, the 2nd brass thing and the 3rd brass thing seem to have screwdriver grooves. According to Redzintimidator, the 3rd Brass thing is the idle jet. What is the 2nd Brass thing?
Can / should that one be removed and clean as well?
Do any pieces pring out / tricky to put that 2nd brass thing back in?

Thanks for the info. My 2000 F4 seems to be running crappy at idle. It might start but it sounds like its about to die, even with the choke on. When the choke is off it dies. With the choke on, you can get it moving and if you're lucky it wont shut off on you until you stop. I followed the how-to, but skipped out on cleaning the idle jet mentioned. I will be taking the carbs apart once again to clean them out and this time I will clean the idle jet as stated.
Since I will be going through the trouble again, I want to know what that 2nd brass thing is and if it can be removed and cleaned.

Thanks once again.

Cleaning the jets is the most important part and 80% of the time that is the problem. Never seen a jet being loose...lol They are usually really really tight in there!

  • Ignore the markings on the spark plug leads and make your own. When you disconnect the plug in chamber 1, mark that lead with a sharpie marker "1" and so on. There's no guarantees the existing markings are correct. But your own markings will be.
  • If you're using a standard deep socket to get to the plugs, the easiest way is to simply drop the socket into the chamber over the plug then attach the extension. Have a magnetic pickup tool handy too.
  • Putting them back in, hand tighten the plugs first. If it seems stuck in the slightest, STOP. If the threads get messed up in the chamber cause the plug wasn't in right and you forced it, it can screw that chamber's compression.
  • If you know any mechanically adept 5 year olds, get him to do it for you. Or wear gloves with knuckle protection cause fitting your hand in there will suck

The service manual form here has a section about syncing the carbs. Chapter 3 pg 13. I know nothing about it, just passing the info on. (BTW it's a large file)

yea you get a screwdriver and disconnect the boots from the bike. Its kinda tight in there, might be able to just muscle it off. Throttle cables too! make sure those are off..lol
