    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.

Can I use carbs from a 821100 on my 80 750E?

Just curious. they sure to look similar, but I just want to check and make sure. Any advice would be helpful.

Thanks!

You can probably use them but they are bigger than the stock carbs. You will probably have some jetting issues. The 750 has 32mm carbs where as the 1100 has 34mm carbs
 
That might actually work out great because I need to do a stage three jet kit on the 750 carbs so I can likely find a nice in between jetting that would work well.
 
Sure, you can do it, but be prepared for a jetting NIGHTMARE. :D

Unless your bike is built with a big-bore kit and radical cams, it won't flow enough air to use the larger carbs effectively.

It's kind of like sticking a big Holley four-barrel carb on a Focus, it's just not going to work well.

The good news is that I found some new mixture screws, which are the sticking point as I can't get the old ones out! Any ideas on that subject? I even have an extractor set but the bit is too big for this hole otherwise I'd let it rip. I see that I have to be careful in this touchy area. I have to get these boogers out though. Any help or advice is appreciated.
 
DON'T USE THE EXTRACTOR SET. :eek:

Your best bet will be left-handed drill bits.
They are not as hard to find as you think, they are available at most auto parts stores and Harbor freight.

Cut the tunnel off leading to the screw with a dremel and cut a new notch in the screw. Spray with PJ1 and hit with some heat with a propane torch or similar. Make sure the slides are removed before using heat.

Actually, if you use one of the larger, reinforced cut-off wheels, you don't need to cut the tunnel off, just cut your slot down it, too.

It will look like these two carbs when you are done:
