    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. 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.

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

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    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.

Assumes the engine is otherwise in good condition. Very important to get the steps completed in order. Otherwise you'll chase your tail trying to get it right.

(anyone who has experience with dynamic convergence on older colour TVs will understand)
 
I have spent a lot of time tweaking a set of Mikuni CVs, but they were the pair on my old 240Z (SU copies). I never used a vac guage on them, even though I had an SU synch tool on hand. You can tune them just like a guitar by sticking a rubber tube in your ear, inserting it in the mouth of the carb and listening to the hiss. It was faster and better than the synch tool for me in this particular application. I used the same technique to synch the Mikuni slide carbs on my RZ350, too. I have not tried this with a four carb setup, but rest assured, when I do have to synch up a set of four, I'll try this method first, before trying to find a synch setup. It works better for me as I have very good relative pitch. There are more ways than one to skin a cat.
 
I just did a carb tear down this past weekend and tried the carb sync using the drill bit method since it seemed like a logical way to go (I've known about this from multi-carb setups on cars). It didn't work for me. I noticed that the main idle screw affects the throttle plates differently also. You have no idea where to set the main idle screw first since there is no published spec. This method would work at least to get you into the ballpark, if there were some published specs as to where to set everything at initially.
