Maybe the knee out and ass off the bike is something other than the ideal Monster position.....
Just trying to analyze and offer a second thought here
If you're off that far it's not easy to control a bike that has too little weight and poor suspension up front.
There is, or should be, more lean angle available before you really need to hang off like that.
I'm larger than you, but I corner well without upsetting my bike at all - just by climbing the tank and pointing my upper body.
It's not necessarily the recipe for your improvement, but maybe it's worth a try....
This picture is before I started pointing my upper body - still plenty fast
