    Right rear tire wear

    We have been running karts there for 5 or 6 years. This is my sons third year in sprints, when he has time off work. On Friday nights they still race karts, quads and 600 sprints.

    Right rear tire wear

    If you ride high on the straights on this track it will slow you down, a lot. They could easily fit 2 more karts beside these 4.

    Right rear tire wear

    For argument sake here are a couple pictures of the track. One from the track website and one a screenshot from google earth.

    I think he meant to say caster.

    Right rear tire wear

    Yeah I have. After the race the RR is still hotter than the other 3 and still shows a lot of wear.

    Right rear tire wear

    Alvin, I don’t have the radius of the turns but on slicks we found 1 inch of stagger was where we wanted to be. I stepped the track off a few years ago but I don’t remember what I came up with. We have been running this same kart for I think 4 years. I bought it race ready from someone at our...

    Right rear tire wear

    Maybe the wear is normal. A couple of the guys at the track noticed the wear and we were talking about it. Theirs are not showing any wear. But they are running in the back, maybe it is just the price of being fast? I was just curious if there was anything in particular I should look at. I will...

    Right rear tire wear

    It is an older Legend kart. It may have adjustments that I havnt found yet. To weigh it I found a level spot on the shop floor, checked level across each scale and corner to corner. I painted the floor so the scales go in the same place each time, each scale on the same corner each time. We...

    Right rear tire wear

    Scale weight is 360 minimum she weighs in at 374. I use 4 bathroom scales zeroed with known 10 pound weights, but I don’t think they are very accurate. I don’t think her kart has adjustable caster. We made adjustments at the track with the weight jack on the left rear or sliding the left rear in...

    Right rear tire wear

    Found my notes. This year we started with Front 46 left 57 cross 60. We started with 2.5 inch stagger on the rear until I found a narrow left rear wheel, now the stagger on the back is 1 1/2. Front stagger is still stuck at 1 3/4. At the beginning she was loose coming off the corners so I...

    Right rear tire wear

    What would cause the left rear tire to wear more than the other 3 tires? The inside edge of the tread is feathering and the tread squares look like they are feathering to the inside. Our track went to the Hoosier predator rules this year. Stock predator engines with Hoosier D20 treads. Running a...

    Neck brace

    This is what we use. For flat karts they work well. The Hans type devices catch on the back of the seat.

    Auto Techs - How bad is buying used cars in the future going to be?

    I have been a shade tree mechanic since the late 80’s. Went to tech school in 88. Left before I could finish because I was needed on the family ranch. I started working on peoples cars in my spare time making extra money. I always had one in the shop and at least 2 in the yard waiting. I quit...
