First of all I do not know anyone personally at Pinsonnault Racing.
I have seen some posts made by them as well as reviews by members that were all positive at http://www.kxriders.com.
I have also spoke briefly with them on the phone.
From my short experience they seemed to be friendly and knowledgeable.
So I sent off my KX500 crank to them for a rebuilt, weld, true, and balance.
I also sent them my own rod kit that was one of the last IMS Pro series rods I could find.
I've had it in storage for about 3 years waiting for this rebuild.
I had the crank back in about 3 weeks from when I sent it off.
For as busy as they are, I felt this turn around time was excellent.
Here is what I received back from them.
Ah ha!
A box within a box is always a good sign.
Due to their weight, crank shafts are easy to bend up the threaded ends during shipment.
If you look at the inner box you will see that it came from Hot Rods.
Nothing wrong with using a competitors box as we do it all the time.
But believe me, Hot Rods wishes they could turn a product out this nice.
After opening the box we discovered that the crank is wrapped in plastic and foam fitted to the box.
Nice..
After removing the plastic I noticed that the threaded end is covered by a rubber end cover.
This just keeps getting better.
The next thing I notice is the welds.
First class job.
Looks like a machine did it.
After checking the radial runout, and the rod to crank clearance, I put the crank into my V blocks, set up my Best Test indicator, sprayed a little Tri Flow onto the journals to prevent any potential sticky readings.
With this indicator I can see imperfections as small as 1/10 of 1000th of an inch, or .0001", probably less.
Here is the set up.
How much runout was there?
ZERO!
Another person (Motorrad) did this same test and said that he thought his indicator was broke because his readings were so perfect.
Well, I had the same experience.
As I spun the crank around I expected to see .0001 somewhere.
I didn't.
In fact I had to keep pulling my indicator away from the journals to be sure that it was actually touching the journals.
I have no way of measuring it more accurately and I have to say that in my view it is as close to perfect as you can get.
I must say that so far, I am thoroughly impressed and will rate them 5 out of 5 Perfect stars ....
The next test will be after I get the engine built so I can see how well it is balanced so stay tuned
