The "sticker" just doesn't happen on a gasgas... My EC has a hi/low beam, horn, tail/stop lamp and provisions for signals should they be required- all of this is "homologation" provision- but does not get you the federal sticker... If Alaska is like WI then unfortunately the only way to be legit is to be less than honest.
Download a title application for AK, fill it out and look for the box that needs to be checked claiming that the sticker is present. Check it. Write a check, put the application/check/original title in an envelope and then cross fingers.
I'm not really down with suggesting someone be dishonest but there's simply not another way around it. Also, as suggested above, get it insured.
Good luck
