Filing down Clutch hub/basket grooves

[GabrielGoes]

Just thinking: filing down the grooves is great to get that smooth operation back but the wear will most certainly will happen faster next time on this soft aluminum.

I have heard of a "mod's" for this. Are there any solutions other than just replacing the entire unit once filing is no longer an option? Would be nice if there was a way to surface harden the areas where the clutch discs gouge out and create the grooves.

Some plates, not sure if they are OEM or not, have flared edges that spread out the load a bit, which slows down the groove forming.

File all the rough spots and gouges out. It won't be an issue.

Was at the 100K mark when the notches started giving me trouble, but there was a tremendous amount of town riding in that, probably 80%, so lots of clutch action. After filing the notches down, that basket lasted until the engine came out, at least 40K later.
On another engine that had done 80K+, there was no discernable notching, but the majority of its life had been country backroads.

I wonder what welding and remilling the grooves would cost.

That's good data!

I'd doubt if you could stop distortion happening. Not really feasible.

Probably too much...I have seen some motocross works bikes and they had stainless channels,sleeves,covering the contact areas.Could possibly fabricate some at a reasonable price with the right material and tooling for the gs's.But the dirt bikes are wide open and shut down with braking effect.Beats the baskets up pretty fast.I have filed down and smoothed them also. no problems.Within reason..
