Idles high on choke. Don't know if there is a way to adjust it

Welcome to the site !!

A little more info is needed , Jetting specs (Main Jet , Pilot Jet , Needle Clip Position from Top of Needle ,Elevation you are at/that the bike is ridden at)

Is the bike "new" to you ?? , or have you had it a while ??

Does it idle "normal" when the choke is off ?? (idle is consistent ,not going up/down)

What are you considering "high" , was it idling lower on choke before ?? , then started going higher ??

Did the bike sit for a few months with gas in it and now is basically the first bit of running ??

Is the Air Filter clean ??

Does it backfire when revved ?? (it will slightly while on the stand if you rev it high , but if it also does it when revving or when letting off the gas while riding , then its a lean condition) or possible tight Intake Valves

Have you checked the Valve Lash ??

The more info on the events leading up to this and what you have checked will help a lot in trying to diagnose this issue .....
