    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. 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...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Clutch won't engage

The pressure plate pushes out at least 3/16" when the clutch is pulled in, that should be enough I would think.
 
I wonder if there isn't some more sinister going on. If the inner hub were binding I wouldn't expect it to creep forward when the clutch is pulled in and the start button is hit (I know I didn't say anything about this before), unless the clutch doesn't work the way I think it does. Since I just cleaned all the plates I wouldn't think there would be enough friction to creep it forward with the pressure plate off of the friction plates.

I will take it all apart and have a look at it. Anything else I should be looking for?
 
how thick of oil are you using? and did you check to see if there was any warp on the steel plates?
blue heat marks are something to look for also. on the steel plates
 
I put in valvoline motorcyle oil 10w40. Didn't notice any heat marks on the steel plates and just did somewhat of a visual inspection for warpage, I don't know that I have a flat enough surface for the 0.1 mm tolerance to use a feeler gauge (maybe I can use the dining room table if the wife isn't home).

The bike has been started a few times in the last few weeks, but it hasn't been ridden in probably over a year.
 
OK, I think I've got this now.:dancing: The crankshaft spins the outer hub of the clutch basket. When the pressure plate is engaged through friction the plates turn the inner hub which spins the final drive. When the pressure plate is off the outer hub still spins but the inner hub doesn't (at least isn't forced to). However, the inner hub goes through the outer hub and has the previously mentioned bearing so the two can spin independently. If the bearing is binding then they will spin as a single unit regardless of the plates.

at least it is really easy to get into. I'd get a few in town miles on the clutch before getting too excited on how it grabbs or slipps.
kinda knock the storage sticky-ness off of the working surfaces.
 
I was just trying to get an understanding of how the clutch works and how that bearing binding could be the cause of my troubles. Still need to fix it, but at least it makes sense now.
