    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...

    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.

Mikuni VM Carb Interchange?

A friend of mine asked me to take a look at his '77 Yamaha RD400. While it's a nice looking bike, it stalls at idle frequently.

My question for y'all: Mr. Barr sells a nice kit of o-rings for the Mikuni VM carbs. Is there any reason to think his kit would work for the Yamaha installation?

I'm sure reed valves and two stroke make for a host of different jetting configurations. However, It seems possible that the other parts may work.

I already checked with Robert, unfortunately, he has never played with the Yamaha carb.

Does anyone have any experience to share?

Thanks, Alan
 
The RD400 was built from '76-'79

There were very few O-rings for those carbs. I'd take them apart and then take inventory of what you need.

Shows it on the 78 model year though. Maybe i made my assumption based on it not being listed for 77...which may be an error on Partsfish.
