2 Strokes Down Under

Just trying to find somewhere that makes custom forged pistons for 2t,s these days i mean it i just want 1 or 2 not a shit load.tried wiseco no result.

Wossner?

yes Wosner, but you need to buy 4 at $200 a pop

And you will need to send them either cad drawings or a piston to copy.

Thanks guys i will give them a call.

Contact wosner online via online enquiry.

If its for the kr there are other piston options mate, just speak to people with experience with KRs. There are plenty of options

I have a matr at a bike shop who said he has a list and they just cross refrance the sizes he also said wossner were a good thing.i just want to find pistons before i pull it down its still going but its just down on comp are thease 84 kr,s nical plated bores?

all you need is

-matching bore size (or larger if you want to bore it out and replate)
-matching piston pin size (or adapt it with different small end bearings
-matching skirt length (or longer) this is usually done by simple finding a bike with the same stroke or longer
-same compression height (taller will require you to make a spacer plate to go under cylinder, shorter will require you to machine the cylinder base.

check if your piston is worn, if the piston is OK I would consider just buying rings from YAHOO JAPAN auctions and putting them in your current pistons

I wish i could find a kr piston to meshure without takeing mine out.it would suck to pull you engine apart onley to find you cant get any pistons i wonder how many kr owners have done that lol i am almost affraid to know what my internals are like.

you're better off doing a compression test to check the rings, pill the cylinder off and inspect the piston and bore.

If everything is OK (piston isnt worn/damaged), clean everything thoroughly, install new small end bearings and put it back together!

if thats all it needs, then thats all it needs
