1985 CR 125 clutch problem

1985 CR 125 clutch problem

Looking for help on a "project" bike. Did a lot of engine work (full
tear down) only to find the clutch action does not give enough travel
to disengage the pressure plate. Seems like there is a transfer
action in the left main case that I do not understand, nor do I see
any info on it in the Clymer manual that I got with it. Any help?

BTW, the Honda shop was no help on viewing externally, so that is
all working OK. All other engine actions normal, ie, shifting,
starting, running thru power band.

Could be a warped clutch plate, or just out of adjustment. If it only
grabs at a cold start up, that could be normal.

You did put the ball bearing back in between the clutch pushrod
and the clutch lifter (the piece that lifts the pressure plate)?

Re: 1985 CR 125 clutch problem

I have an entire '85 CR125 sitting in pieces in the shed
out back. My right side engine / water pump cover is so
corroded as to be unrepairable. I searched to a replacement
and so far have found none to exist.
So the motor is pretty much junk for my needs.
I may be up for parting out the motor in whole or in part
if someone needs something specific.
I'd like to keep the rolling chassis for a future CR250XF
Thumper project though.
Gud Luk with your clutch problem, sorry I don't have an
answer.

Re: 1985 CR 125 clutch problem

I had a 1992 YZ125 in a similar state that was given to me. I had the
idea of putting the Pampera engine in it, lower it and give Tracy a
better chassis. But, it was too much work to use such an old bike. I
gave up on the idea for now and used Craig's list to get rid of the
bike in a couple hours.

the regular clutch info mentioned above is detailed in the manual and
is working fine, the throw of the clutch action seems adequate but
does not get the pressure plate off enough to disengage it. Thanks
for any and all inputs, but I think the problem is inside the left
main case, on what transfers the action from the cable over to the
push rod. It is not visible, and when I had the cases split in the
past I still could not really get an eye it. So I ask all this
because hoping to have a clear idea that this can be fixed before I
split the cases. This may be something I could buy from SloCalSpode
(the part or the left inner case) and will try to send a direct
email.

thanks again, Doug

I could be wrong, but I don't think you need to split the cases to do
any repair on the clutch or any of the clutch mechanisms.

I don't think so either but.;... is the actuator in a weird place,
like the
bottom front of the cases? Or is it in the standard location, just
above
and in front of the countershaft sprocket?

If it's in the normal place, pull the circlip and pull it out. There
is a
ramp on the end that pushes the end of the pushrod. See if that is
damaged.

Another thought: If the clutch basket is worn, it could prevent the
discs from separating completely, just as well as not letting them
gain contact.

I think what Hank and I are getting to is - take the clutch and
it's associated parts apart carefully before you tear into the cases.
Everything we've suggested so far can be done with the engine
in the frame.

Pull the clutch cover, pull the spings and pressure plate, make
sure the ball is down the pushrod hole, pull the plates and make
sure the outer hub (or inner for that matter) hasn't got grooves
worn in it, pull the actuator. If you still haven't found an issue,
maybe then take the motor out and start tearing apart
cases. Though I can't think of a thing in there that could
make the clutch not work. Even a missing spacer would
probably be on the end of the input shaft behind the clutch,
not inside the cases.


Go fast. Take chances.
