When the bike is in gear the rear tire spins(not freely as if the bike is in neutral) however when I apply the clutch THEN it locks up as if it is in gear.

Clutch or Transmission issues
- Thread starter YamahaSpecial
- Start date
Are you describing these symptoms with the bike on centerstand, engine running?
Just so we're all on he same page terminology-wise.... a brake is applied.... a clutch is engaged or disengaged?

Bike on center stand, engine off. Manually spinning the tires in gear when clutch is engaged and disengaged

Can you apply the rear brake and hold it on by stuffing a board or something, transmission in gear (1st or 2nd) pull the clutch lever and feel the clutch discs slip by turning the rear wheel?
I've broken stuck clutch discs loose with the engine running in this way. Using the foot rear brake pedal and clutch lever.
So do you think your clutch discs are stuck?

If it slips when engaged and locks up with the clutch disengaged (pulled in) it means your clutch is adjusted WAY to tight. It’s actually contacting the inside of the primary cover and jamming when you pull the clutch lever in. You need to loosen the cable and adjust the clutch.

Is there a possibility something is stuck then because the clutch nut/bolt adjuster is backed almost all the way out to where when I pull the clutch lever in you don’t see the adjuster thing spiral inward.

I’ll try this. No clue if the discs are stuck.
I’m assuming you’re asking me to start the bike, apply the rear brake, pull in the clutch lever, put it in 1st and see if it engages?
If it’s “locking up” when you disengage I would be VERY hesitant to start it. You could cause some serious/expensive damage. If it were mine I would take the primary cover off and disassemble the clutch and see what’s going on. Sounds like something is assembled wrong or broken.

So I can start it in 1st, I can start it in 2nd. When I start it in neutral I can shift gears and the bike doesn’t move or make grinding noises.
Only time it starts to make a noise is when I disengage the clutch(squeeze the clutch lever) but it still doesn’t try to move
Not sure that I understand exactly but I once had a clutch that worked perfect
Could shift and start and Whatnot in all gears.
But pulling in the clutch handle and there was abnormal sound.
Letting go it disappeared
That was the clutch hitting the inside of the engine cover.
There was visible marks on the inside of the cover.
I don't know why it was so Perhaps the wrong Clutch plates . In those days one ordered via catalogue and mail
post stamp .
And i Suspect it was the wrong ones. Who knew and could check. Before installation.

took me a few times of reading that but I see what your saying. It’s the clutch that’s acting up when engaged or disengaged.

This is what is happening to me. But I haven’t checked for the rubbing just yet.
Just replaced the oil, there goes $25 if I need to pull that cover right?. Haha
What I was trying to speak to was terminology. When you say apply... we typically think of applying something... such as a brake. We could also apply counter-steering.... apply some wax...
A clutch doesn't get applied, you either engage a clutch so the engine turns the rear wheel... or disengage a clutch to remove power from the rear wheel. The word apply doesn't really....well... "apply" when discussing clutch action.... sorry, pun intended.

Find some soft padding and lay the bike over on it's left side. The cover can then come off and all the oil will stay in the motor.

Thanks Jim, I’ll give it a shot.
Since my short time here I’ve got her cleaned up pretty well, electrical works great, needed a few new bulbs, brakes work(had to rebuild the front caliper), changed oil filter and sump filter, replaced a broken turn indicator stud, new spark plugs, disassembled a d cleaned the carbs.
She’s running but need to solve the clutch issue before it’s drivable.
The first time I took the clutch cover off my '78, this is what I discovered .....
It wasn't rubbing at the time but obviously someone did something wrong in the past. When you pull your cover, I would pull the clutch lever in a few times and observe how much the pressure plate moves out, or if it moves at all. You should probably inspect your worm in the left cover. I think I might do that first before pulling the right cover. The worm should rotate in even if the adjuster is all loosened up, as long as the cable is still connected to it. You said yours wasn't rotating. With the male part of the worm screwed in fully, it should end up about like this .....
There are 4 "swirls" on the worm so it's possible to start screwing it in in 4 different positions. Only one will give you the proper screwed in fully position. It will end up off 90° to 180° if started in any of the other 3 wrong positions. To have it end up correctly, start it with the arm pointing to the right, to the 3 o'clock position .....

You may find that your clutch actuator is mangled, that can cause the problems you are experiencing. Ask me how I know…

I think removing my right cover and looking at the plates would be my next steps.
(Previously)The clutch lever had no resistance and would also not spring back so I removed the left cover found the cable detached and cleaned every inch, removed the worm and greased it, put it together(it does match the picture you show)
I did notice the ball bearing in the worm, cleaned it and greased it. When putting the cover back on the wormhole with the bearing in side slides over a long rod that goes inside the clutch that had a seal around it, Both the rod a d seal were covered in grease so I carefully removed the build up, then removed the rod to further clean and grease it before sliding it back into the seal that goes into the clutch… before I slid it in I did look in there with a flash light, and I believe I saw a bearing in there too. Based on online service manuals and YouTube videos I watched everything looks right from the left side.
