How to tell if clutch needs replacement
 

So my boy was hot rodding around and messed his bike up. It wont go now. I believe its the clutch.

I took the primary apart and the oil smells terribly burnt. I took the clutch plates and spring out of the clutch basket.

Nothing looks wrong. But im no mechanic. Can any one describe how a bad clutch looks?

Or post pictures for comparison?

If its a burnt smell he probably fried the clutch and it needs replaced

<p>Check the splines on the clutch basket.</p>

You'll want to measure the thickness of the friction plates and look at the steel plates. If there's any bluing on the steel plates, that's a dead giveaway.

When was the fluid last changed, and clutch adjusted?
Could be the clutch became in need of adjustment and possibly a good primary fluid change.
If nothing looks wrong then I would adjust the clutch and install some new fluid.
Run it.

That would be the visual inspection required. I would first do a complete clutch adjustment though. I've got over 60k on my clutch plates with virtually no wear.. I also don't try to do burnouts.


Possible... but if he lost all his splines it would be grinding bad as it would not be a 'smooth' shear.

Depends on if the clutch simply "went away" or 'bang-stopped-working'.

However, since I was just in my primary, I know that '07 and up will fracturre/shear the inner splines on the clutch hub.

"Won't go"--- what does that mean? Do you still have the spring load feel on the clutch lever? Did he snap the belt, and it is gone, I've done that? Will it go into gear and not move? Will it move and shift but slips? A bit more info please

Yep, too vague on the symptom description.

Yep, for sure.

The OP said he took the clutch plates out, and asked what a bad clutch would look like. That's a fairly specific question.
