From the pics, I'll stay using the Pro-X for the Banshee's.
One thing I don't like... is they copied the stock clip tang design, they let the pin rub them, then they break off in the engine. All modern pistons have a cutout notch in the piston next to the pin hole to use a 'C' clip with no tang to break off.
As a performance builder, I want the Banshee bigger intake windows in the intake skirt for more performance with a hotrod setup.
IMO!

Thanks Chuck for this input! Did not know such could happen!!

Apart from this issue, are these good and reliable ones?

Cheers,

With today manufacturing quality...I would think your fine for a stock bike and maybe with some chambers.
Don't take a chance with the ring expanders breaking, just throw them in the trash and put on the 2nd ring without them.
Here in the states our premium fuels are ethanol base, so with the extra heat of this pump fuel, I run no less the .002in piston clearance and .0025in.
with larger overbores and hotrodded engine work.

Thanks for your valuable inputs, Chuck!

Had been using OE Art only. Have tried Pro-x once.  Lemme try this stuff for once and see. The seller rates his product very high.

One more thing, Chuck.

I have desisted from using Wisecos as forged ones rattle too much. Would you rate Wisecos above Pro-x? How about Wossner?

Hi,

Was browsing for 3rd over Piston Kits for my Air cooled RD350, when I came across multiple websites listing Wiseco Pro-lite 513M06475. They have listed these for YAM RZ350s and Banshee ATVs.

Kindly let me know if any of us has used it in their AC RDs and if yes, what is been their experience.

Cheers
