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.

1979 GS850 Front Master Cylinder kits.

I am looking for some advice for rebuilding my front master cylinder. I have found the kits for my rear but it's been difficult to find the correct front piston set for my model bike. Some sites claim its for my bike but then state in the fitment chart that it's for much later models.

Would anyone have pictures of the right piston for my bike? The OEM diagram on partszilla is difficult to spot details that would help identify the right piston online.

Would it be wise to replace my front master cylinder with a similar setup from another bike?
