Dearest mechanic friends please help!

Bike is a 1999 Honda CB250 and I love it to death. The clutch was shitty when I bought the bike (gear changes really clunky on the pedal and won't shift into neutral if the engine is running - really unhelpful when I'm stopped at a red light and realised I haven't done my helmet up!).

So I finally decided to put new clutch plates in and now the gear pedal is smooth and delicious. I replaced the clutch cable too because the old one was stretched and worn. Put it all back together, new oil in, adjusted the new cable all to manual specs. No worries. Started it up in neutral, clutch in, put it in first and the bike shot forward and stalled. First I assumed I didn't set up the new cable correctly and the clutch wasn't engaging/disengaging properly. But after much adjusting, I don't believe that's the case.

So I drained the oil, took the crank case cover off again and had a look. I suspected I didn't do the lock nut up tightly enough, so I went to tighten it. When I previously undid and redid this nut, I depressed the rear brake first otherwise the rear wheel would just spin with my tightening. But now, when I depress the brake, the clutch spins as I try tighten it.

I haven't touched the rear wheel or brakes at all since I've done this work.

What the heck?!

Can someone please shed some light on what I've done wrong here? Desperately missing riding my moto thanks in advance

Wish I could help but I'm not a clutch expert.
You need someone who IS to help you out.....onsite.
Or have a shop come pick it up.

NOTE: For future reference, given the symptoms you reported, the only real problem MIGHT have been the stretched clutch cable.

Unfortunately I've tried to T that up but all the bike shops in my area are slammed and have a minimum 2 week wait 😟

If you have cast alloy wheels then a block of wood between the swing arm and the bike in gear should stop the clutch from spinning. If you have spoke wheels then you cannot do this. If the clutch still spins despite the rear wheel being locked then you need to jam the gear wheel from the crank to the clutch basket.

People will tell you not to use a large flat screw driver between the drives but I have successfully done this in the past you need to be careful not to chip a tooth. Alternatively you can fashion an 'S' shaped piece of 1/8 x 1 inch flat bar that will fit between the gear drives to lock it into position.

good luck

I'm going to give Aussie Steve's suggestions a red hot crack! I do have cast alloy wheels and enough desperation 🤪

Yeah just make sure you don't trap any lines from the brakes or similar. The wood will need to go in the direction of rotation that the clutch basket is going to spin....clockwise would be my guess so probably under the swing arm if you are tightening the centre nut.

Good luck
