redzintimidator: Good post, my idle jets were filthy. After a cleaning i can see through them much better.

Ive almost completed this, have the carbs mounted back on and almost all the lines hooked up.
I have a question on 4 vacume lines. They are located under the carbs on the engine, one for each cylinder. The lines are these.

Now whats confusing and there are 4 spots directly above them on each carb, and 4 spots for them on the air box

Carb spots. The 4 nipples under the bowls.

Where do those vacume lines off the engine go?

If they go on the airbox. What goes on the 4 nipples on the carbs pictured?

those 4 nipples on the carbs are for nothing. They are just to drain the bowls.

I dont know what those vac lines are. They aren't on my F3...maybe something for cali emissions??

Those lines go from down by the block to the air cleaner then, which i kinda figured since they are pictured with the air cleaner parts. Does for F3 what any hose on those carb drains or are they just left open with nothing attached?

I was damn impressed with this step by step guide that I decided to clean mine. I have an F3 and it has been a b*gger to start. Checked sparks OK bit sooty but nothing major. Valve clearances were only checked by a garage (if they actually did it!) last year so they should be fine. So I was thinking carbs....based on plenty of posts in these forums. I dont ride very often so it is possible that there has been some varnishing in the carbs.

SO got my Haynes Manual out and a print out of theis great guide and off we go.... Except I ended up putting everything back exactly as it was. Could I get access to the retaining screws at the base of each carb to get them off. Like hell. I canno tbelieve anyone can get their mits down there let alone with a screwdriver, which makes me think you can only clean your carbs if you get your engine out.

SO thats where I am at. IT may be something else. My choke seems shot. On cold start with choke on I dont ever get a start without a blip on the throttle to help things out. And then I need to take choke off fast or it screws up the mix and engine dies. Can anyone think of anything else it might be? Its not the end of the world it starts but when the owner manual says never use throttle and choke on start ("hardstarting" I think they call it) I think things are only going to get worse. Its not the battery.

Excellent write up, really helped me :). The hardest part I had was removing the carbs. HOLY SHIT! For those that are doing this for the first time, there are also upper band clamps that need to be loose.

I'm doing this tomorrow. I'm pretty excited my F2 has been running like garbage. I broke down a few weeks ago and I drain the bowls and black gas comes out, it's full of what looks like rust particles, I cleaned my gas tank out and now it's time for some carb cleaning. I can't wait to get my F2 running like a dream.

Great write up, I did mine last night since my bike isn't starting and I was replacing the plugs I figured I may as well do this while I have it all apart. The two things I struggled with most were just getting the carbs off the bike itself and dealing with those stupid gasket and springs on the vacuum chamber, those things can be a punk to get back together!

I guess the question I have is do the carbs need synch'd everytime you clean them? I ask this because I don't have the tools required to do this job.

Thanks,
Jason

I'm thinking those lines are for synchronizing the carbs using the right equipment, my mechanic buddy installed them on my bike when he was inspecting through it last year. I have three of them, coming off the block and going to three solid plugs on the airbox.

The MOST important part of cleaning carbs is completely NOT here. You have to take out the jets (all of them) and insure they are whistle clean. Main jet, pilot/starter jet, etc....ESPECIALLY the pilot/starter jet. It has the smallest orifice and will gum up fast. Makes bike impossible to start and/or keep running on idle without choke. There is way more to this than pulling the float off and cleaning the bowl !!!
