1983-1985 KDX200 Wiseco Piston Order

Postby mwoj » 12:31 pm May 15 2018

Hello all! As some of you on this forum know, Im looking to rebuild a few of my 1985 KDX 200 engines. I am highly considering doing a special order from Wiesco. Ive heard a rough estimate that you need to order 10 in order for them to make them. I understand this will cost a lot, probably around $2k-$3k if I had to guess. I would probably keep 4-5 of them for myself. I am just curious if people would be interested in buying them if I make the order. I wouldnt want to be stuck with so many extra pistons...

I still have to make the call and get a real estimate...but I am trying to make my life a lot easier, and hopefully help out some other people as well. So if youre interested, or have gone this route before, please let me know.

lemme call em...
Thank you, Julien D for all your hard work!

PLEASE! Do not "dip" PWK Keihin carbs in Berryman's to clean them! It will damage the internal o-ring (jet block gasket).

gone for the day...

I think it is a minimum of 12. They USED to make a piston for 1983 - 1985, so I hope they can just go get the old mold / materials / whatever instead of having to make a new one.

I don't have a need for one myself, but it would be great to have that option for those who want them.

If this guy is leaving some room for him to make a profit, then no way it is REALLY expensive. He is selling four for $620, which is $155 each. That is not too bad compared to eBay NOS prices.

EDIT ADD ON: Another place had a pair of Honda pistons custom Wiseco for $350.

EDIT AGAIN: Did you try the Wossner??

Hey sorry for such a late reply. Ive been super busy and forgot about this. I honestly dont think I have the technically ability to fill in everything on the special order Wossner form. Do you think I should fill out the Wiseco form or call them?

I would just call and ask. Years ago, they used to make one for the 1983 - 1985 KDX200. Maybe they did not throw the mold or die or parts (whatever they have) and can just make some more without a bid deal.

Look around on this forum. Someone showed a Wossner piston inside the bore with the pin not fully being shown. I would buy a Wossner and check the fit before buying 12 Wisecos.

I chatted with a Wiseco employee. He said they didn't have any of the specifications of the old piston design, so it would be a normal custom order. A minimum order of 12 is required.
