Need advice While I learn

[12Bravo]

This is what I have;
Throttle Slide #7
Main Jet Unknown
Pilot Jet #35
Needle: N1EC

This is what is happening, sluggish on the bottom but hits hard 1/2+ throttle.
Throttle off idle 0-1/4 is ok, but not super crisp.
Have to turn the idle screw in to keep idle in N and in Gear. N idles high in gear idles slow, really slow sometimes stalls.
Throttle 1/4-WOT seems to be good.
Location: 1200' up to 3500' elevation temperature now in the 60-70 degrees F.
What I am looking for, more Bottom end and less top end. Slow trails and beginner rider, I don't need crazy top end!

Gearing is 12/48, plan to get a 13 and leave the 48 on rear, unless you all say that's no good. The bike seems to be set up for the track, I want to set it up for trails.
