Wondering if anyone knows if Nissin makes an upgrade to the stock 954's master cylinder?

5/8", isn't that whats in there already? Thats the 929 size. That would be a 16mm. If you have a 14mm or 1/2" then the 5/8 is what you called an 'upgrade'. Remember, bigger dosen't necessarily mean better for master cyls. Sometimes it means less feel or oversensitivity.
