If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

I have not done a seach as I only have dial up so please bear with me.
This is how I would do a bench sync on my CVs

1 Assemble carbs ready to go on the bike
2 Set air screws 1 1/2 turns from bottom.
3 Determin master carb.The one that the throttle cable connects to right?
4 Put a small drill bit 1.5mm under the buterfly of the master carb. (to big/small)
5 Adjust the main idle screw untill the butterfly just touches the drill bit.
6 Adjust the sync screws untill all of the butterflys are the same.
7 Check the master carb again.
8 Reset the idle screw

Have I missed or got anything wrong?
Cheers
 
That should work. I use a flexable feeler guage. #3 is the master carb.
 
Procedure sounds good. \\:D/

Only things I would change would be to start at 2 full turns out and use a smaller gauge. I have had a couple sets of carbs that would not open to 1.5 mm, so I use a straightened-out paper clip. The larger ones I have available at home are 1.05 mm in diameter, the 'normal' size clips are 0.88 mm. Just be sure that there are no burrs on the end of the clip that will scratch the throat of the carb.

Also, don't forget to re-set the idle speed before starting the bike. With the throttle open far enough to do the bench sync, revs will tend to skyrocket when started. :shock:

Thanks Chef and Steve.

Good to know I am on the right track.:-D

Cheers
 
The only thing I would add is to make sure the #3 throdle blade is completely closed with the idle screw backed out. You never know what was done in the past

Also a good point.

What I tend to do when finished is to back off the idle screw until there is a gap in the adjuster, then shine a light through all the carb throats to verify that they all are closed, then do a visual sync as I turn the idle adjuster until it touches, then about one turn more.
