WPC Treatments for your motorcycle.
What is WPC Treatments?
Basically it is Micro shot peening surface metals.
Steel, Aluminum, bronze, even Nikasil plating can be treated.
So I went on Youtube and watched the two demonstrations done by Izumi, the owner of WPC Treatments.
Ok, looks promising but how does those demonstrations translate into motorcycle parts?
Most of us know that shot peening makes the surface metal harder... But peening needle bearings and bushings? I admit I was a bit skeptical. So I had some parts WPC treated and decided to do a very garage like test to see if there was any noticeable differences between treated and untreated.
Here is the set up..

Like I said, it's a very garage like test...
But the results were very close to one another.

1st test. I ran this set up with the WPC treated bushing and bearing. The trans shaft and the clutch basket were untreated.

2nd test. I ran this set up with a brand new untreated bushing and bearing... Same trans shaft and basket.

3rd test. I ran this set up with a used bearing and bushing... Same trans shaft and basket.

4th test. Because some will complain about my unscientific method of testing I ran the WPC treated parts again with a worn battery and duplicated my initial results.

I ran each test 5 times.
I tossed out the high number and the low number (They were very close) then averaged the three middle numbers.

The WPC Treated part ran for an average of 36.19 seconds.
Now you have to guess how long the untreated new bearing and collar ran for :lol:

The WPC treated was the clear winner...
The WPC Treated part ran for an average of 36.2 seconds.
The worn bearing and collar ran for an average of 20.3 seconds.
The brand new Factory bearing and collar ran for an average of 10.6 seconds.

So, there is a few things to learn here.
1. The WPC treatment works and works well.
My personal bikes will not get built without this treatment.
So yes, I give this process a 10/10 rating.... You NEED this..

2. Loose is fast as my buddy Adam Millar always says.
He is right.
I guess that is why a engine is the fastest right before it blows :lol:

Any questions?
Feel free to ask...

Would having the clutch basket and inner hub done be a good idea as well?

Yes, steel or aluminum that rubs or rolls on or against another part should be treated.
The piston, rings, new cylinder plating, trans, gears, shift forks, shift drum, shift shaft, roller bearings that can be disassembled (Clutch bearing, wrist pin bearing) exhaust valve parts, do them all.
