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...

Master Cylinder question about parts

Got a new master cylinder today and tore it apart to clean it. Trying to put it back together, and something isn't right. I'm not sure of the order for the pieces of the piston. I've tried a couple different ways, but every time when I try to pull the lever a couple times, the piston gets stuck and takes a beating to get it to come back out.

I've looked at the manual, but I'm not sure if the piston cup is the rubber thing, or if it's the part that's pressed in the end of the spring.
 
You may need to replace those parts all together.
Did you clean the bore of the master?
 
I guess the part I keep getting hung up on - if the rubber piece goes at the bottom, wouldn't it block the hole leading to the brake line?
 
The rubber piece also has wear marks that match the bottom of the piston, so I'm almost certain they go together.
 
Todd forgot how it goes together.;)

This is the correct way.:D

This photo is a rear master, but the parts fit together the same way...

I honestly cant remember which bike these parts are from. IIRC it was the 82 650 I had for a brief time.
