Hit a pot hole the other day now I'm noticing a wobble from the front of my scooter when riding. Any clues to what it can be?

It may be a bent rim or damage to the tire. Have you put the scoot on its center stand then tilted it back so the front wheel can spin and see how it behaves?

Sometimes that's the sign of broken tire cords (the back-bone of the tire itself). The cords keep the shape/contour of the tire, and when they break the rubber can bubble out causing a lump. I would do what pinkscoot mentioned and lift the front wheel off the ground and give it a lil spin, you should be able to notice any deformalities.

wobble can also mean loose neck bearings.. While you have your scoot on the double stand tilted back to see how the tire/wheel spin grab a hold of the front wheel and see if you feel any shake in the front end. If you do, the neck bearings are/have become loose.
Easy to snug up, loosen jam nut on to of the bearing nut ( top of the top tree ) snug up the nut (don't go overboard) then re-tighten jam nut.

It might be easier to grab onto the handlebars while in front of the bike, or seated, and attempt to move them forward and backward. If the bearings are loose, you will feel some motion that is arrested pretty quickly.(depending on how loose) Likely loose bearings will not give a wobble by them self. They will allow a wobble to be more noticeable as the wobble can more farther before being stopped mechanically by the bearings. I would do as two above have suggested. Place some weight on the seat to keep the rear tire on the ground, and the front tire elevated. Get positioned so you can readily spin the front tire. I'd sit on the ground next to the tire. Give it a spin. If the wheel has obvious wobble, either being out-of-round(sight across the center of the tread, and watch to see if the center moves up & down) or a bent wheel(sight from the front, spinning the wheel, and note if the wheel seems to move side-to-side) Look at the edge of the rim while doing the two above sightings. If the rim moves more than a small amount, likely it is bent. If pressed steel, it may be possible to whang it straight again. Big hammer necessary along with strong arm. If cast aluminum, (the fancier models with matching painted and/or polished metal wheels), they are not easily straightened. One last thing to note is the 'triple tree' that makes up the front fork. Two legs from the middle down to the axle are designed to be straight, viewed head on or from the side. If bowed, start looking for a replacement. The upper part, with the 'neck bearings' is also supposed to be straight, without bends. If it is bent, again, start looking. New steel wheels are not vere expensive. Tires can be had at acceptable(to some) prices. Not worth the possibility of injury to be riding on damaged wheel, tire or tree. Repairs are cheap compared to hospital bills. IMO. tom
