HELP! Master Cylinder rebuild for 550L

[CA180]

Help guys, i'm trying to track down a master cylinder rebuild kit for a front master on an 80 (81?) GS550L.... I'm not sure what year it is classified as because it says it was made 12/80... But Z1 classifies is as an 81 because of the frame numbers (JS1GN71L_B_100001 <- per Z1)

Any way, they don't seem to offer one anymore and I talked to a guy up there and he said there isn't an aftermarket or OEM one either.

Help me out! I got loads of gunk in this thing and some torn rubbers! (and thats never good!)

Your bike is an '81.

My suggestion is to get the OE rebuild kit, P/N 59600-33810. Ordered a K&L master kit from Z1 for my 850 and the piston did not fit - binding in the bore. Z1 did not stand behind the product so it sits in a box...while the OE parts are happily working in my bike.

Sweet, and thats the one that works on my bike? I thought suzuki no longer offered it, or was I misled?

Round M/C or Rectangular?

Round with the (slightly) angled reservoir cup

Well, according to this site a rebuild kit isn't available for an 81 550l


But the master looks the same as all the others, wonder if it is different... Or maybe mine isn't original.

Babbits doesn't even show a 1981 GS550L. If you go to the 550T, the part number I listed above is available. I'm pretty sure the master is the same since Alpha Sport lists the same part number for the 550L piston kit. http://www.alpha-sports.com/suzuki_parts.htm

Thanks, I'll give that a shot... Any good places to order from that might have a decent return policy in the event it doesn't work? :-D

I'm not doubting you, but I don't want to be stuck like you said you were

Suzuki part # 59600-33810 as Nessism said.

This is an old thread but I just have to say my K&L master cylinder rebuild kit fit as good as OEM, no binding, noises, or anything.
