Is piston worth salvaging?

[speedyslyder]

Lol. You guys know to much for me.maybe ill cut a hole in the top of the piston to make it move faster in the cylinder as well.by the way i run br9es ngk plug.

OHHH great br9 plug make sure the plug is gapped at 0.12 or nearly touching electode for best results

i have been thinking about running the hottest gases on the planet with a ngk 6 heat ranged plug or the hottest they make still experimenting though?

we like whats going on with you my kids dance to you
But you cannot come on a professional website with a hack piston and expect
sincere advice buddy...LIKE I SAID YAMAHA AND PISTON MANUFACTURES WILL BE ALL OVER YOU FOR THE NEW BULLET PROOF DESIGNseriously you have good intentions and curious on results as always

I like your spirit Thompson!
The spirit to experiment, try new things. What makes it work?
Sometimes you have to test the paradigms to see if the walls are real.
Not a zombie or sheep, following the crowd. I like your spirit.
You don't just copy what you heard, you test it out. Right on!

As much as I'd like to see how this would work out, I see a problem.
The piston needs surface area to stabilize it in the bore or it will rock in the bore.
While a modern 450 4 stroke piston is as short as this piston, it still has a tiny skirt.
Without the stabilization the piston will rock in the bore, maybe break the other skirt or damage the bore.

Try it if you like, but the risk is likely damage to this cylinder and possibly to the crank and case if the exhaust skirt breaks off. Speculation on my part, I could always be wrong...

Exactly what i was thinking when it comes to the short skirt on the 450. wont the rings stabilize the piston in the cylinder? Btw thanks for acknowledging my optimistic spirit

No, rings won't do it. Need a skirt and you have none.
That is the sole purpose of the skirt, piston stabilization, and you don't have one.
The 450 pistons (and stroker automotive stuff) are examples of skirts taken to the minimum.
The cost is short life. Many 450s demand piston changes at 15-30hrs.
Hell, I go on 15hr rides!
