From post #36...

"The only other screw I have access to is the pilot air screw?? I think is what its called, its on the venturri opening on the air box side."


This led me to believe you were describing the air jet thats on the front of the carb throat on the air box side...which in turn prompted my response that it just bgets screwed in and tightened down. If you jammed the bottom PILOT SCREWS down you may have broken all the tips off in them ports.

Nowhere did anyone mention to turn them in and leave them. Lets get some ternminology out of the way here.

MIXTURE SCREWS...The ones on the top rear of the carb throats that you can see from above when the carbs are on the bike.

PILOT SCREWS..The ones on the bottom in the back behind the carb bowls ( VM carbs )..you can not see them when the carbs are on the bike.

AIR JETS..The brass ones on the bottom left of the carb throats on the airbox side. You would be looking straight down the carb throats to see them.

Which one of the above 3 did you turn all the way in? AND if it was #2, did you get physical and really tighten them down like you would do when just putting in a bolt or something??

I turned the air jet screws in. The bike started this morning and is running fine. Im missing two air jet screws. My mixture screws are fine and I don't see and "pilot screws" on my carbs, but I have CV carbs, not VM carbs. Where can I get replacement air screws?
 
Take pictures of what you want and point to it please. You keep saying air jet SCREWS and there is no such thing!!!!!!!!!! You have air JETS and you have mixture SCREWS. The mixture SCREW is the ones on TOP of the carbs and at the rear behind the top covers.

Air JETS are in the front of the carbs throat at the lower left side. Brass slotted jet.

Which are you specifically saying are missing?
 
These are air JETS and get tightened in and are not adjusted....

Back here is the mixture screws which ARE adjusted to tune the carb to the cylinder.....

Air Jets are what I am missing. Im missing two of them. Bike still seems to run fine without them. Still would like to get them back in.
 
True that..seems those two cylinders would be real lean and even harder to get dialed in. Remove one thats there and see what the number on it isand see if someone has them.
 
I dropped out quite a while back, due to your unwillingness to accept suggestions. :eek:

We suggested an airbox, you fought it. You have finally gotten one (and found that we were right).

We suggested cleaning the carbs, you said they were cleaned, now we find that the plugs are still on the mixture screws.

Now we find that the pilot air jets are being called "screws" and are being adjusted.

It was suggested to turn the mixture screws out 2 1/2 turns from lightly-seated, then fine-tune from there.
Now you say that you set them all to 2 turns and it won't run.

See why I dropped out? I am as patient as the next guy, but ... :-\\\

When you realize that some of us just might know what we are talking about and start accepting some of the suggestions offered,
you might be amazed that you will soon have a well-running bike.

You can lead a horse to water, but so why do we always have to carry the horse?
 
No I didn't take the mixture plugs out at first when I cleaned the carbs, they are now out. The bike runs right now, just needs the "fine tuning" as you guys are talking about. I cant do a carb balance on the bike bc there are no vacuum ports.

Chuck, thank you, I will remove one of the others and look for some numbers to find replacments.

Because the plugs were not removed when you "cleaned" the carbs, we can only continue to wonder about how well the carbs were "cleaned".

To properly clean the carbs, they need to be soaked in some rather harsh chemicals. Those chemicals tend to destroy rubber bits. The o-ring that is around the mixture screw under that plug is one of those "rubber bits".

Because we know that that o-ring was not changed, we can only continue to wonder whether the rest of the o-rings were changed.

The wonder continues. Do you know what you are looking for? :-k

Here it is, straight from the service manual (you do have a manual, don't you?):

But Steve don't we get second chances for looking at the clymer motor cycle maintenance collage?
 
Take some fine steel wool and clean the faces of the air jets..should be a number on them..which is the size.
 
Steve, my bike does not have those ports on the intake boots. I know that its suppose to, but it doesn't. Im not sure as to why but they aren't there.
 
Are you sure that the boots aren't mounted backwards so the ports point inward instead of outward like they're supposed to? They wouldn't be obvious and visible. If not then you simply have the incorrect boots and will have no way to perform the vacuum sync.
 
JTG, I pulled the boots off to have a better look at them and nothing. They've gotta be the wrong boots for this bike.
 
You could drill new vacuum ports. Put them up on top where you can get to them easily. Having them hidden underneath where you can't get to them is ludicrous, a complete failure on Suzuki's part to think about what they were doing..
