    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...

1990 gs550l rear brake master cylinder

Forum Newbie
Hey I just have a simple question. I have a 1980 gs550l with a bad rear master cylinder. Most rebuild kits or replacements say 79 or 81. Are these swappable at all? Thank you
 
There is no L model listed for 1990. Theres an E model. Recheck the manufacturing date as listed on the VIN sticker on the steering head.
 
Think the OP needs to get something straight first.
which is it?

Chuck's list is incomplete. 69600-45820 fits the 1980 GS550L
 
Reasonably sure it will fit, but just for kicks I punched the above link to Partzilla, It has a place to put in your bike to see if this part fits. I put in the info. it asks for. Motorsport, street, 1980, Suzuki, GS550L, and that site plainly says does not fit your 1980 Suzuki GS550L... Still be hard to believe it don't fit, heck it fits everything else.

I would trust alpha sports parts look up. ive always used them.

Nope. They leave out applicable parts. Go check yourself. Search 1980 GS550L, and you will see. It calls for the same PN as you show above, but your search doesn't show it.
 
Totally think this fits, just say'in if you put the info in that little box that says "check if this fits your ride" it says does not fit your 1980 Suzuki GS550L... Do see how this Partzilla ad may be confusing.
 
Sorry definitely a 1980. I just know sometimes there’s weird one off year things. Like even the petcock on it is only one year for this model I believe. But I will go for it. Thanks for the help.
