Can i fit a YD100 cylinder kit on a Avenger 85?

The bushing won't last long. That was one of the major flaws with the V1 phantom 85, and alot of home built saw engines

I'm not saying to eliminate the wrist pin bearing, just use a bushing to make it fit.
For example, a 10 mm wrist pin with a piece of 10 to 12 bushing would fit on the connecting rod for a 12 mm wrist pin and still fit the 10 mm piston.

Here are some, they say bearings but use them as spacers.

I think you could find steel ones, which would be stronger.
