"B" designation on kawasaki pistons
« on: December 04, 2003, 05:46:11 AM »
What is with the "B" designationon kawasaki pistons when looking at the microfiche:

PISTON-ENGINE,(B)

What does this stand for?

Also:  Are "Pro-X" pistons pretty good?  Which is better Kawasaki Genuine or Pro X?  Who is a good online vendor to buy a piston kit from?

Thanks
Rob

Pro X are OE pistons, made in the same factory and everything :)

The answers to the letter designation on your piston can be found if you CLICK HERE

Scott,

If you are changing pistons, consider the Wiseco pistons. I have only good experience of them so far. They actually improved the overall performance of my bikes and they are cheaper than the originals.

Errrr, If you look at the top of the page you will see that is rdg2 otherwise known as Rob who was asking about pistons and I was just replying to his question :)

I have an awfully nice Wiseco fitted in my KX and they are also lighter than stock :D

Sorry,

I was confused there, should have said Rob not Scott. My mistake! But then again, I am confused most of the time...

I have used both ProX and Wiseco with good success.  Ironically, the only piston I have ever broken was a stock unit.  Fortunately, low RPM failure, so no damage.

Opt for either unit depending upon availability and price.

Good Luck

I think the "B" is for a larger piston to take up some of the side clearance on a worn cylinder..its just to tighten things up...Am i right guy's?
I use Wiseco pistons/best pistons in the world...they are a work of art!!

My opinion is use the Wiseco!
Better, much lighter and give a better throttleresponse :D
You get cracks in the orginalpiston below the wristpin inside the piston.
When you buy a new piston campfer the piston-ends at the skirt,you got better oilfilm inside the cylinder if you do that.
How many of you desertriders drill a boosthole in the piston?

never drilled port hole for KX500....but i had several CR500's that i drilled relief holes in the piston in line with the exhaust port bridge to carry extra lubricant.
I am curious about the boosthole though!
