Got my 86 454 to start but it stalls whenever I let the throttle go. Also noticed that the drivers side throttle cable going to the carb doesn’t move when pulling the gas back. Don’t know where to go from here

first off what do you mean drivers side? if you are in the uk we drive on the left the correct side!!, so are you talking about the left carb when sitting on the bike, the pull cable should open both the carbs together and the push cable close both, if this is not happening question 1 is why not. i would take the carbs off and where the pull cable connects manualy opperate this arm to see if both carbs open, both should rise together, if only one opens then the problem will be the closed one. if you are lucky it may be just stuck, if not inspect the parts clean or replace any that are faulty if you go on to cmsnl.com type in en450 they have a pictures of all the parts which makes life easier. good luck

That's a carb clean rebuild job, no other option really otherwise you'll never be able to diagnose how its running. Get the carb rebuild kit its fairly cheap and check out some YT vids on a 500 twin carb rebuild. Be careful its one of the most delicate parts of the bike and will likely need some solvents and compressed air but can be done in a day (or perhaps a weekend if its full of gunk). Sounds like you'll also need to lube the cables which is much easier with a cable lube tool and I'd suggest using a temp fuel supply while you test and tune the carbs on the refit.
