Okay I know this is SUUUUUUPER late to the game but as a owner of 3 of these here's a few things:
1) Steering will be janky no matter how many times you replace rust with Alabama chrome. Best bet is to get some (or have some made) heavy duty front spindles, and tie rods because these are notorious or being flimsy. Even a steering rack from an ATV or golf cart would be better.
2) Replace the rear axle with a standard 1" round live axle setup. They are a 7/8" aluminum hex which are a dying breed because they just don't hold up to severe roughriding and have been known to bend at a feather's weight (Found that out after a small jump) Not to mention the wheels are specific to this style axle. You can find the 4 lug hub adapters here and there but it's easier just to go with what's common. Plus you can run whatever brakes, sprockets, or other drives you want off of it without special hub adapters.
3) Brakes on this thing SUCK. So make sure you compensate for braking with early deceleration. Once they get used twice they heat up and tend to glaze. I put double drums on one of mine and that held up to a 13hp with about 280lbs of rider.
These are very very fun machines and they roll like a champ. The frames are strong, body fabrication is pretty easy, and it's comfortable for any size or shaped rider who can fit in it. Just keep in mind while they may be janky from factory they tend to grow on you after a while with some minor mods.
