Your line can definitely be improved however you also are dealing with some equipment issues.

On the GSXR a lot has to do with the shallow swingarm angle but it also doesn't help that you're on stock suspension that's underdamped for your weight.

I'll address the swingarm issue first.
Because it's relatively shallow once the rear axle crosses the plane of the pivot bolt the rear squats significantly causing two issues: the front rakes out significantly causing the bike to run wide, and if you're accelerating the drive chain can pull the tire away from the pavement.

The rear shock being undersprung/valved for your weight complicates the above issue as it compresses too much under load also contributing to the above issue.
As you've gotten faster you're reaching the limits of what the stock suspension and geometry can handle.

I remember us having this conversation a few months ago. Hopefully Christmas time will allow me to upgrade the suspension on this bike.

For now, I'll continue to work on building better lines.
