    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.

how can I identify a 36mm from a 33mm ?

is there some difference on the outside or it's the jet ?

tell me


thanx
 
It's the measurement taken across the bore of the carb at the engine side. You'll need to remove the carbs to measure it, I don't think you can tell by looking at the outside.
 
The 36mm CV type carb has a "kind of" square top like this:

Most all of the CV type carbs have this square top.



The 33mm smoothbore (Mikuni) has a narrow rectangular cap on top of the carb. I tried to find some photos of them on the internet but failed.

I hope this helped.

Searched for "Mikuni smoothbore" on Google and this is what I got.

That is one of the flat slide smoothbores. I'm not sure if they make or ever made a 33mm flatslide. The flatslides are suppose to be an improvement over the round slide carbs.

I believe that carb is an HSR, for Harleys, and other single carb bikes. The smallest RS carbs are 34mm, while I believe the smoothbores come in 29 and 33
