You can of course do whatever you want, but I wonder why you are experimenting so much with fuel?
Most people here run their NSRs on leadfree pump gas 97octane, with great success.
I use it for trackdays where the bike never comes below 8000rpm with no problems.

There is no need to complicate things. These bikes are streetbikes, not Mars vehicles

I suggest that you check if there are any airleaks anywhere, check your oilmixture(it affects the air/gas ratio) use pumpgas, NGK BR9ECM sparkplugs and then get the jetting right.
