Gator 50cc 4stroke 2016. Has no power. Only runs 20 mph. No washer in variator. No needle adjust. 82 to 85 jet made it worse. Can I get a derestricted cdi that will help this unit?

 What's the story? Has it ever ran well for you or did you just get it and this is how it is? You should not need performance parts to top 20MPH. Most stock 4T scooters will go 30-35MPH in stock form if they're running right.

Healthy should run something like 150psi.
Has it sat around with old gas? If so, drain it, clean the carb, and go over the fuel system.

To ride it you probably need at least 120psi
I like mine around 150- 170psi or so.
Too high and it'll run hot, be hard to start and pound the bearings.

To answer the question, yes, a valve adjustment might help, especially if the valves need adjustment. If mis-adjusted, the valves may not seat well causing compression to be lower than normal. That definitely could affect starting and power developed, moreso when hot.
