sorry guys, im still noob on computers. wrong pic that one.

here is the under shot. notice the reenforcement on the prox, yet none on the wiseco.

heres my baby. 2001 with 90-91 plastics/graphix

im sure somebody near you will glady take the wiseco off your hands then go buy a new one of your choice. i think that prox you have is the one that short circuits out the exhaust so its junk also

thanks 100hp,

OEM piston and gaskets

it would be cheaper too if you bought a cometic top end gasket kit

I bought a 90 mm Wiesco from Glen, it was a nice light machined one. I was going to go with Wossner but they don't have any rings yet. They make a 84-89 model year piston which is basically the same as the 90-01, it's forged, it has anti scuff coating on the skirt and are real nice pistons. Unfortunately LA Sleeve is the dist for the country so the price will be high. All pistons are made in Germany.

I have never had problems with forged pistons, if they are bored in correctly, and you break them in right, they last for years. problem is, you just can't jump on your bike, fire it up and give it hell until the motor is up to temp and the bigger the slug, the more it needs to be warmed up.

i have a pair of Rocky Cycle 89.25mm pistons on the shelf

thanks bud, but i picked up a vertex89.5 2 weeks age for $120 shipped.just waiting for it to get here

cool

Lol, I still have a brand new oem cr 500 piston sitting on my tv. never been used.

I bought my cr 500 used, figured, I'd buy a piston and ring for it before I needed it. I shoulda took the motor apart I guess first. Went with stock bore when I ordered, turned out the motor has a .50 over bore wiseco piston it.

Lol, took motor apart to throw the new piston in it. I look at the old piston, and the new one, they don't look the same size. I push piston in cyclinder and theres like so much play I am like F***ing bs.

Throw old piston back in, order a wiseco 50 over bore..

And my awesome dealership here in town won't take back the piston cause I can't find the box it came in, but they will return the rings. lol.


So I have a brand new piston sitting on top of my tv. ahh well. its shiny

I tell everyone how much I love the honda store in town. lol. I never shop there any more (but theres a different reason I don't shop there anymore not because of this piston issue.)

I happen to be in Germany right now and also happen to need a new piston. What is the difference between the 84-89 and the 90-01 piston? I can price out the wossner's and fly home with some if anyone else wants to try one.http://www.woessner-kolben.de/english/indexenglish.html

I had a new old style Wiseco, it had the sides cut out like that prox, and it didn't have any cast lines or crud still inside it. Sold that puppy for a premium to some sucker. My Vertex looks like new right now and the cylinder is still perfect. I hammer that thing in the dunes and when I smell molton lava out the tail pipe, I rest it.

That wiseco looks just like mine, and i am right about 100hrs straight MX on that thing. still runs like a raped gorilla. I have no probs with wiseco.

yeah i couldn find anyone to sell it to so im running it to judge for myself. threw it in in february and managed a few rides so far so its almost run in.
the engine feels a little down on power but thats prob cos im using a different cylinder that has the scollops in it. it really feels like its robbing the bottom end.
my last cylinder was a 90mm with a vertex (as opposed too this 89.25mm) and it had noticably more bottom end.
