The big issue that most of us had with Wiseco's in the first place was their consistency.
When they started making pistons outside of the US the quality went way down hill.
The problems covered just about every aspect of the piston from excessive ring gap to land thickness, and everything in between.
If you got a good one, no worries... Run it...
With the Wossners, they have been consistently good.
My understanding is that Wiseco has been improving their quality control.
Good for them if they are...
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.
