    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.

Hi
From which bike(from 1985 and on) I can take the carb set for gs1000e 1980 bs34ss and its bolt on without any modification?

The GSXR carbs 36mm Flatside will work but they will have to be jetted.
You'll also have to buy K&N filters for these carbs.
I do believe the years for these carbs are 88-91

I HAVE ALWAYS WANTED TO KNOW,WHAT IS A FLATSIDE CARBURETOR, AND WHY ARE THEY BETTER?

The problem in the design stems from the basic slide design. Its length and the shape below the slide promote turbulence which hinders proper airflow and atomization. The key problem is that (when looking at the front of the slide) the back part of slide is much lower than the front and the transition is not airstreamed. The incoming air hits the back of the slide and then bounces down toward the needle jet and what is not deflected down is spun into the inlet.

This problem is minimized on flatslides by making them much shorter; that generates a stronger pulse below the slide because the air flow is increased. On the D-slide [as on PWK] this problem is even further rectified by making the slide even shorter and the mid section of the slide is airflowed to minimize turbulence.
 
Thanks! What then are 'semi-flat' and do they offer a significant performance advantage over the stock carbs ('82 1100E).......I am talking about the 36mm's off a Suzuki RF900 (1994). Or are they not worth the bother?

Any of the flatslides or semi-flatslids will be better than the round slides. The true flatslide are the best but when you get those from the GSXR or the RF900 bolted on and jetted it makes a huge difference. You just have to make sure that they get jetted in right.
