What exactly is so bad about these wheels?

OK, I got a little more work done on the kart. More pictures.

I am building a Viper ST. I really like these plans. This is as far as I got so far. I ran out of welding wire. Here are some pictures.

You should take a look at the Viper ST, and the STX. The plans are free at mxk.com. I built a Viper STX. It was easy to make, and the plans were easy enough to follow. I have a thread with pictures in the photo gallery section. It is on page 2 right now, I have not updated it in a while. I am...

I finished the kart, but I didn't update this thread. I could not get the throttle cable to stay in place the way the plans show, I had to atatch the cable end dirrectly to the gas pedal. The throttle linkage plan makes a good throttle/pedal return, but the cable end would not stay in place...

I built a Viper STX with the free plans on their website. I did not buy any kit or any other parts from them.

I thought someone would have commented on how odd it seems (at least to me) to have the front wheels wider apart than the rear wheels. Anyway I made spacers to set the rear wheels out more, to be more inline with the front wheels. I got the engine on, but I still need a chain and I need cables...

This is from the Viper ST, and Viper STX plans. The plans are free at mxk.com. I am building a Viper STX right now.

That is not my kart, it is from the plans. I forgot to say I am making the rear axle wider to match the front. It should be easier to re-do the rear, than the front.

I don't have much of an update. I have a clutch and a brake, but I want to re-do the frame where the engine mounts. The plans make the front axle wider than the rear. I built it like the plans, but now I want the front and rear wheels to be even.

I was talking about the spindles in the plans. What I was saying is, if you build the spindle assemblies exactly like the plans. I would think they would then be better suited pointing forward. That is probably why I had trouble with them pointing backwards. If that is still not clear enough...

Well, the plans have the spindle arms to the outside of the pivot/kinpin. For the Ackermann thing I need to be more to the inside. You can see the difference between Sids picture and the plans. The plans do say you can change the spindle assemblies from left to right to get the arms to point...

Ok...Yes, the steering is messed up. I did build them like the plans. I reworked the spindle arms, but I don't have a picture right now. About it being one wheel drive, I am fine with that.

The brakes, or actually a brake will be a 4" drum brake and band that mounts to the spocket. Just like in the plans. I still need to make an order for the brake and clutch.

The engine is the Harbor Freight Tool "Predator" 212cc. I still don't have a cluch or brakes, so I started another kart. If you look close you can see I did the spindles/brackets different. Here are some pictures. The paint is just to stop the rust.

OK, I added some paint, a steering wheel, the pedals, and a wheel with a sprocket. I have to redo my rear "axle". My wheel bearings are 3/4", and the plans had me set up for 5/8" bearings. No big deal, that should be easy to fix. I got an engine today, but I didn't mount it, because I don't have...

I added the front extension, that makes a big difference. The kart is kind of small without the extension. Here are some more pictures. Maybe somebody here has already built a Viper, I don't know.

I am building a Viper STX. The plans are free at mxk.com. I think the plans are pretty good actually. It was kind of easy to build too. I did do some things different, but mostly I kept to the plans. Here is a picture of where I was at after the first weekend.

Free plans at buildyourowngokart.com. I am going to make that one next.

OK, mxk.com, then click on "Free Gokart Plan". Then click on "Free Gokart Plans (BETA TEST)". The page will look like a forum. Then under where it says Subject click on what you want to see. Tie Rods, Figure H, Figure G , A&B, F, E, C&D, Motor Mount Plate, ect. You can print the pictures, or...
