    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...

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.

Is there a difference between a single and dual MC on a 81 gs750. Im guessing that the duals have more capacity but not sure.

thanks,

eric
 
The difference is in the flow of fluid per stroke. If you install a mater from a dual disk bike on another bike with a single disk, There will be reduced travel and feedback on the front brake lever. I've tried it and I wouldnt say its terrible, but it is different. You may or may not feel comfortable with it or like it.

I would not do the opposite and install a single master onto a dual system. I'm not sure there would be enough fluid displacment to operate the front brakes satisfactorily.

sorry, i didnt get to be very thurough(sp) before since they actually want me to work around here.
My situation is that I have a 82 gs750TZ which has the drum rears and single front disks. My parts bike (81' 750E) has disks rear and dual disk front. I am switching these over but the mastercylinder is busted in the parts bike. I wasnt sure if I could have used mine (single) for the new setup (dual). I assumed its a bad idea to use the single.

thanks,

eric
 
I have a master cylinder from an 650L model, and from a 650G model (82). The M/C from the G model is all rusty and seized, so I was planning on using the L model M/C (cuz I know it works). I'm going to have to check my service manual, and find out what the difference is. From the P/n's at Alpha motorsports, looks like diameter.
 
i got one on the way, cant wait to get this thing back on the road. It will be nice to actually have back brakes (drums were either no brakes or locked up).
 
do you guys happen to know if all the round type of master cylinders where the same. The one i got (not sure what model its from) is missing the diaphram, i just wanted to make sure before I order one.
