My friend and I made a Go-Kart for my autotech class. It was a competition for a local community college to raise interest in the automotive program. We built it from complete scratch into our own design. We raced it in a slalom and a drag race against other high schools. We won the mechanical skills competition and the drag race, but lost the slalom by less than a second. We made one last year but that was a mile off the ground lol. I dont have a picture of last years but here's this years:
Stats:
chinese replica of a honda 250cc quad engine
air cooled
4 up, reverse down shifting
hydraulic disk brake rear only
electric start
straightpiped lol
chinese replica carb
15 tooth front sprocket
45 tooth rear sprocket
#40 chain
built on a budget of $1000
I finally finished editing all the photos and getting them in an order I like. So heres the actual build:
We used an old brake rotor to bend some 1.5" strap so make our drop spindles.
Tackin up the strap on the plates we had cut
1.5" tube used in the center holes. The ends of the plates are about 86° apart so about -4° of camber.
Initial mock-up with front axle completed
$50 seat from Jegs
Ebay Special 250cc (Honda XR replica) air cooled four stroke with quad transmission (4 up + reverse)
Tacked up frame
Final frame design tacked up. We actually had to take it apart and put it back together because one side was a couple inches off and not square. We tacked the front spindles down and clamped the rear down while we placed some 1/4" plates under the middle before we welded it up to give the frame some natural camber.
Another shot of the gusseting. Gussets are 3/4" frame is 1" tube.
Weldzor
Artsy welding pics lol. Shooting welding is actually really fun. So many cool motion blurs and lighting effects.
We pre ran the car and then decided to clear coat the exhaust, tierods, and shifter linkage. Even though we used high temp paint the pipe rusted up and lost the beautiful color. Tie rods and shifter linkage still look great though
Heres a pic of what our shop at our High School looked like. Scotchbriting the frame getting it ready for paint.

Assembly of the front after paint. The tall black lever is the the shifter and the lever on it is the clutch.
Another of the front end. Diamond mesh where your heels go.
Rear end shot before installing the axle
We hid the wiring here. Voltage rectifier, CDI, coil, and kill switch. The red wire all wrapped up is the recharge for the battery which might eventually get installed. Right now we just use a jumper box and connect it directly to the positive on the starter.
rear end
Cantilever for the brake. Brake pedal pulls the top forward pushing the piston upwards. Polished aluminum, one of my favorite parts of the cart
