Gt500 master cylinder

I need to rebuild my master cylinder. I have fluid leaking from the base of the cup and at the handle. I have found this ebay rebuild kit, but I can not find anything on the fiche that looks like these parts. So my question is this what I need to buy.

Thanks

There were two different master cylinders used on the GT500 - the kit you've flagged is for the Nissin, and the full part number is 59600-45821. It is still available from Suzuki for about $31 in USD. The other type is by ASCO, and the kit is 59600-33810. This is also still available from Suzuki for about $33 in USD. I'm not sure what fiche list you are looking at, but I normally use the ones available here, as some of the others do not show the discontinued part numbers.

Hope that helps. 8)

If it's leaking from the cup base, you may just need to replace the o-ring. Part numbers are 59686-33620 or 59686-33600 depending on the brand of cylinder.
Go here and look up your bike. You can determine which on you have from the pics.
