Q4: Stock piston? KDX220
I just removed the piston from my 2001 KDX220.
Is this the stock piston? It has an arrow and the letter C on the top.

Re: Q4: Stock piston? KDX220
Kinda looks stock/cast. Just about every Wiseco piston I've seen has quite a few numbers laser engraved on the top. What does the underside look like? Does it say 'Art'? (I think that's what the stock piston says, not 100% sure.) The forged Wiseco looks forged on the underside (not surprisingly
). IIRC, the Wisecos have a 'W' on the underside. I'm pretty sure that's stock; don't think it's a Wiseco.

I think it is stock, as OEM has the letters. Grab a sheet of paper from the printer. Place it on a shelf. Turn piston upside down and put on paper. You now have a parts holder. Please do not put anything heavy in the partsholder, as the parts holder has been known to shatter, especially when ran for 17 years. ![Razz :razz:](./images/smilies/icon_razz.gif)

Inside the skirt it says "SK" and "2". There is a checkerboard pattern underneath the top. It does look like a sandcasting with some pitting. There are sharp edges and ridges. But I do not see the letters "ART".Jim B wrote:Kinda looks stock/cast. Just about every Wiseco piston I've seen has quite a few numbers laser engraved on the top. What does the underside look like?

Just about positive that's stock/cast. You're lucky that didn't grenade. The wear looks pretty minimal.

I am glad too! The bike only has roughly 1250 miles on it since new.

That is definitely a stock piston. Mine has the "2" w the other marks just like yours on the inside, and the arrow with the "C" on the top.
If you lend someone $20, and never see that person again, it was probably worth it.

So, I am in same situation. I need to replace OEM Piston in my 220. Are all the Wiseco pistons the same size? Or, do I need to correlate them with A, B, or C on my piston head?

I think Wiseco just makes one standard sized piston. They don't do A, B, C, D. The non-standard sized pistons that Wiseco makes are (just for example), 0.5 mm, 1.0 mm, not 0.01, 0.02, 0.03, 0.04 mm like A, B, C, D.lucy wrote:So, I am in same situation.

There is one really cheap brand that almost everyone says to avoid. It might be Mitaka. I am not sure. Vertex, Wiseco and Wossner have good reputations. (and Pro-X, pronounced procks for some reason)

Is yours a 200? (I'm guessing so by your username.) The 200 pistons don't grenade like the 220 pistons. That's still a lot of miles on a piston.kx200 wrote:I too got lucky! I put 7500 miles on before I opened it up.
