Clutch will not engage.
« on: December 02, 2012, 02:12:32 AM »
I have a 98 Honda cr125. I bought it as a basket case. After getting it running I tried to take it on a test drive but the clutch will not engage causing the bike to jerk forward as if I put it in gear without using the clutch. I have replaced the cable, clutch plates, friction plates, and even adjusted the cable and it still will not engage. Also I would pull in the clutch with the clutch cover off and it looks like one side of the clutch doesn't move as far as the other. Any thoughts????

Have you replaced the clutch springs? What kind of fluid are you running in it?

Are all the parts where they supposed to be?

could be springs or pressure plate if the clutch isnt engaging evenly.

quick check would be to swap the spring possitions around and see if the unevenness follows the springs the next place you put them.

I have not changed the springs yet and I used the fluid that the manual specified. Thanks for all of the advise. I'll try these ideas and keep you updated.

Question,
When the bike is running and you pull the clutch in and put it into gear, does it surge forward., or does it not move foward with the clutch lever out.
It's just that you say engage, but when your are talking about clutch action with the cover off, you seem to be describing disengagement.
Best clear that up before diognosis.

It surges forward. Sorry I was under the impression That when you pull in the clutch lever you are engaging the clutch

That means it isn't disengaging. And in that case make sure the cable isn't snapped and is adjusted correctly. After you check that, if there is still a problem, than you should probably take the clutch cover off and see what going on in there.

the cable is good.The clutch pushes out. But when it does it disengages it does unevenly. It seems like one side pushes out farther than the other.

Did the problem start occurring before or after you replaced the clutch components you mentioned?

When mine did that I over tightened the clutch spring bolts. Go back in a double check all your torque measurements. Oh and make sure that pesky little ball bearing that goes on the end of your clutch rod (number 20) is there. Sometimes they drop out and you wouldn't even notice.

Before I replaced the parts
OK, since it's an old problem and not created by the new parts, my first check would be to look at fingers on clutch basket ( #3) these get notched and prevent spreading of the plates, even though the pressure plate is opening.
Try pulling the the entire side cover off (not just clutch cover), pull in the lever and zip tie to the bars, check and see how much movement is in the pressure plate (only needs to be a few mm's) then rock bike back and fowards in gear and see if plates are slipping. If not try and manually spread with a screw driver or the like.
Pictures would be a real help.
Also check to see if all parts are present as per fishe.
