The throttle response will improve with what you did but you may find in cold temps after drilling the slide that if you open the throttle a bit to aggressively at a lower speed that the bike will bog down because it's opening too fast.
The hi jet could be upped a bit too about a 170/175.
Use this as a test for that.
Quick and easy way of testing the main jet size.
Run the bike through the gears into third gear and run third up to 60-70 MPH full throttle, then chop the throttle about 1/8 to 1/4 back and see if the bike either surges ahead or stumbles then recovers.
If it surges ahead, your jetting is lean
If it stumbles and recovers , your jetting is rich
If it makes no difference, you're pretty close.
