Noise after shift mod
I've never had a Superhawk apart before.
I just did a factory Pro shift mod on my wifes bike and while it shifts SO much better, there seems to be a new noise. Maybe in the clutch.
I did line up the clutch basket with the oil pump sprocket pins and I'm sure that the plates are installed correctly. I used an impact to tighten the clutch hub nut. The nut was flush with the end of the shaft, just like it was originally and I staked it. (New nut)
I checked and rechecked as I went along and it all went smoothly, but now there is a new noise. Or maybe just a little louder and it changes slightly when I pull in the clutch. (The clutch operation is fine.) The plates are pretty worn. I didn't measure them though.
Any thoughts?

I would describe it as a rattle or a rotational noise that changes a little with the clutch pulled in... but the operation is normal.
I know it's a little vague. I am just hoping that someone took apart a clutch and then encountered a noise.
The cover housing is very thin and would offer little noise insulation, such as a big Kawasaki would.

My clutch has been apart more than once and is as noisy as !
It quietens down when I pull the lever.
Operates perfectly so I have left it alone.
The noise has been there for approx 3 years and I live with it. Before I disassembled the clutch it was quiet. These bikes are noisy from a mechanical standpoint.
I have read on other forums about people who replaced bearings etc only to have the noise return shortly after.

I found it. I took it apart again and loaded the gears behind the rotor. (Lined them up under tension)
I had neglected to do so and now it runs dead silent again.
I need another cover gasket though...

What Kenmore says is the "Anti rattle" gear.
I turned the plastic gear clockwise against the steel crank gear with a metal punch and then held the spring tension as I re installed the clutch hub assembly. It was a detail that I had missed when I had it apart before. Kind of a P.I.T.A.
Now it sounds great. Like it did.

Yes. The basket must come back off. Load the plastic gear to the right until the teeth line up with the steel gear again and then slide the clutch hub back on,while holding them together under spring pressure and making sure to also align the pins for the oil pump gear. Kind of difficult to do and seemingly un needed. But makes it all quiet.

The rattle gear.The advancer is not in the drawing and does NOT need to be messed with. The plastic gear is behind it and is free spinning. It looks like just one gear, doesn't it? It's a stack of two.
