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.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

My bike wasn't running but after checking things I decided it needed new ignition components. I replaced points/condensors/coils and then the bike fired right up. Problem is only the right side cylinders are getting hot and the bike has no power since its only running on 2 cylinders. I checked the spark on the left side and foudn it to be good but for some reason teh plugs are still wet. I want to try synching the carbs but dont' know where the vacuum ports are that I hook the gauges up to. I dont' have a manual but think i have the procedure pretty well worked out except wehre to hook up the gauges. any help or any websites going through the process step by step?

thanks
 
Not sure if carb synchs are online, but Google might help you.

What kind of bike?

On the bigger GS's, the ports are on the underside of the intake ports. Not on the boots like you'd see on an XS. They're plugged with hex-head bolts. Remove those bolts, put in your adapters, then connect hoses.

If you need adapters, you can get them from Morgan (http://www.carbtune.com/carbaccs.html).

Someone else could probably give you a better idea of the procedure, but basically it goes like this:

1) Attach hoses and warm up bike
2) Get friend/clamp to hold throttle at about 2,500-3,000 rpm
3) You can't adjust carb #3, so adjust the others to match it; the outside two carbs should flow 3cm/Hg higher with a stock airbox. Turn clockwise to lower flow, cc to raise flow
4) When sync'd, lock down adjustment nuts and ride
 
What kind of bike do you have? It's kinda important...

My page on intake o-rings shows a few clear pics of an intake boot and the allen head screw that's (supposed to be) installed in the synchronizing port. Do these ports have screws installed?

This page shows another bike that has the sync ports in the cylinder head, but the principle is the same.

If your plugs are wet, it must be getting fuel.
Since you replaced points and such, what about timing? IF you have spark and fuel and it's not firing, then it may not be firing on the compression stroke.
