Been tinkering with mini motos, mini bikes and razor dune buggies for the last couple years and wanted to get something a little more comfortable. I bought a Leeson motor off ebay for a great deal and after a year of searching I finally picked up a kart racing chassis for a decent price.

Plan:
48 volts
7200 rpms
10T drive sprocket
67T axle sprocket
#35 chain
11.5" tires

Goal:
Have fun and ride around neighborhood with kiddos

Motor:
Leeson
1HP
24vdc
3600 RPM
TEFC

Controller:
Kelly KDZ48400 24v-48v 400a controller

Batteries:
48v
Starting with SLA 12v 18AH. (I have a bunch of them from other projects, but might move on to lipo, leaf, or just larger sla's)

Kart:
Haase stage 2 (First time with a real gokart and learning as I go)

So far the kart is a little rough.. I took off the axle and cleaned it up added a sprocket hub and am now waiting on a new sprocket. And still need to figure out how to mount the seat. Once I have it how I like it, I will strip her back down and paint etc.

Tonight I started on building a bracket for the motor to attach behind the axle. My plan as of now is to put the batteries where the engine would normally go on the kart, and moving them however needed for balance and weight distribution. I am also trying to keep from welding or drilling the frame.

Kiddos' 4th bday was Saturday and also taking care of a 3m old so the build is starting off a little slow.

Ordered new rear axle bearings for her today and just got the cheapo 3pin Chinese foot throttle for it in the mail. Rather then "make" the foot throttle work I am going to go with a pull throttle.

Always a good sign when it comes new with rust.

Not sure where the motor POS wire should go yet.

Kelly i bought off ebay mostly wired up:

Spent some time cleaning up the axle. She spins a hell of a lot smoother now with new bearings. Also a new sprocket hub and 67T #35 sprocket.

Getting closer!

Motor mount is complete! Has the ability to go side to side and back-forth fairly easy. Used a 3/8" plate of aluminum.

And started on the battery tray:

Looks like fun. I've had cars with less stout brake rotors.
Had a good laugh at the "Kelly" controller diagram.

Been slowly making progress. Have the seat mounted and spent way to much time fabing the hall effect sensor for the foot throttle. Next on the agenda is battery placement.
