Project cheap trick

In the first pic is says 82MM in the piston. What is going on there. Stock cast pistons are 83 on the bottom of the skirt and about 82.5 at the ring area.
I was looking at the Wiseco's The MTC looks to have more maternal around the pin area. Did you have to put heavy metal in the crank to get it to balance?

For whatever reason both replacement sets are marked that way. They are proper for 83mm bore. They are drop in when used with the correct pins and weigh the same as stock. These were used in a 430hp riva motor.

I'll take them.

Got my 15F intake and set of ZX12R cams.
My plan is to put the 12:2.1 bike pistons in the motor with the 15F intake and bike cams and put a stand-alone on it and get a feel for what these motors want for timing and learn the stand alone system. I’m curious of how the stock prop with act with a spicy 1200 making steam about 9k. After this it’s low Cr pistons and turbo time.
