carb balance problem

bikerburnout · November 26, 2011, 04:09:59 PM

hey all today i went to balance my carbs on the monster, BUT no matter what i do i just cant seem to get to the balance screw between the carbs (not sure of the real name for that one sorry). Is there a trick to getting to that mother? its a 93 900, the one with the oil rad conveniently placed in you way. I have tryed moving it.

im planning on taking the carbs out 2moz to give all the jets a clean through but that not going to help me balance them as obviously they need to me in the bike and running.

It is a tough spot, but with the right screwdriver all you nÃ©e to do is stand on your head....

A lift helps too.

I never thought about standing on my head. Thanks for the tip

Besides the lift, a long thin screwdriver and good light will help.

Remove the oil cooler, long screwdiver, strong LED flashlight and lay down next to bike on your back with your head at the front wheel/headstock area looking up at just the right angle. There is a relief under the air box which the screwdriver rests in giving an idea of the general direction. Watch out for the front exhaust pipe! With stock carbs its at least easier than some other types of carbs.

Weather forecast for mid north coast NSW OZ looks a bit ordinary for the next few days so may attempt my 1st ever carb balance.
Questions as follows.
Using a motion pro synch pro carb tuner. Instructions say I need to calibrate it each time before use. Attach calibration manifold to non-adjustable master carb. Which one is the master carb?
Next I am to adjust carb adjustment screws so that fluid columns are approx same height. Do I adjust only one screw until balanced and if so which one if i adjust both how will i know which one. Thought there was a vid on carb balancing but haven't been able o find it
Thanks in advance

I'm a fan of penny-tech so I made my own carb synch tool with clear hose and ATF fluid, but this baby is really nice:

Not terribly expensive, it dampens pulses and counts them to give you rpm. Neato.

Don't want to be overly dramatic, but make sure you have the bike secure in a rear stand and brake levers velcroed tight if you want to sync above idle. Just in case the shift lever vibrates into gear.

The master carb is the one you adjust the other one to. If they are synched and your idle rpm or your mix is not in spec you need to go back to adjust your master and resynch.

It does very well, except for the white flake corrosion damage on metal. Came agross this when I tried carb cleaner and ruined some hard to find diaphragms made of rubber on my Yammie's carb. Stupid move on my part. Dipping in Seafoam would work too, but it is more expensive.
