It should be noted that street sidecar outfit, Moto X outfit, roadracing outfit, "Wheel on a stick" outfit, a outfit without a passenger, have NOTHING in common (except for the 3rd wheel) with a LRS outfit using a passenger that work properly and steers straight at speed.......for one thing you need as little sidecar tire contact on the ground as possible (using a kart wheel and tire is way to much tire to ground contact....Kart tires are made to go around corners with as much contact as possible)...We have used a 17x2 1/2 wheel and tire at 50lbs pressure with about maybe 1 inch tire contact to the ground. A properly set up LSR sidecar will not pull either way (left or right) A LSR outfit has to be adjusted to the weight of the passenger and where he/she rides on the platform....has to be adjusted to bike leanin/leanout according to the bikes suspension....has to be adjusted how much sidecar wheel toe/in (again to the location and weight of the passenger) If you got the sidecar wheel to far back in relation to the rear wheel (and using a passenger) at speed not enough weight on the front wheel of the bike to steer properly.....To far forward, and the whole outfit will pull on acceleration. These are just a few points how to build a proper LSR outfit. I have been building road racing sidecars for over 50 years....learning how to make a LSR sidecar work safely took a lot of time and testing.....Our outfits have seen 162mph on salt and 187mph on tarmac all using a passenger at all times. Which makes our sidecars the fastest in the World USING A PASSENGER. "REAL RACING SIDECARS ALWAYS HAVE A PASSENGER IN THE CHAIR"
