Might be a dumb question that I think I know the answer to, but thought I would double check before going through the pain of changing a bunch of components. Currently I am using a small #25 chain on my sons 250W electric go cart, but struggling with the chain jumping off and just not working...

Quick update on my sons cart that needed more lowend torque. Finally got time and found a simple way to add a Jackshaft. Havent tried it yet but hoping this gives him enough lowend power. Sadly, as nice as I thought it turned out, I feel I may need to re-engineer the hole thing :( Couple test...

My logic says this should work fine, but has anyone tried it? Want to create a simple way to adjust the max power on my sons gokart. not only for him depending on where we are riding, but incase other little kids want to ride it I can slow it down. thoughts? Danny

I'm looking to setup a dual electric motor cart with a dead axle, sprocket mounted to the hub on each back wheel. I know a lot of gas carts use a dead axle, how do they typically add brakes, other then tire rubbers? thanx Danny

Is this possible, or is this stupid? I need more torque on my sons little gokart, cant change the motor sprocket to smaller, and dont want to add a jackshaft. current sprocket on the rear is...

Question, On my bigger gokart I used a mechanical Estop instead of a contactor to connect the Battery to the controller. Per the wiring diagram I installed a 1K precharge resistor across the EStop. If I understand correctly, the purpose is to prevent the large inrush current from the caps in...

Im always keeping my eye out for motors on the cheap and found a guy on craigslist with a few including a MY1020 750W (he says) that I might put in my daughter gokart (replacing her 500W) He also has two unmarked motor and no clue what they are. one has a short toothed gear that probably cant be...

So this is my first time dealing with the actually axles portion of the cart. I have modified/upgraded a few carts (mostly converting to electric) but each time kept the main drive hardware. This time I am trying to modify a very small pedal gocart with a 300W motor for my 3yr old. my plan was...

Need some help figuring out how to find matching parts, spent a few hours online and cant seem to find all the pieces that go together... I have n E300 scooter motor that has a #25 sprocket on it. The sprocket has a "D" shaped hole (not sure whats thats called) with a nut to secure it. Sprocket...

Hey guys, been a awhile, lifes way to busy.... Starting a new project for my soon to be 3yr old. I bought an old pedal gocart and going to remove the pedal power, drop a new 3/4 live axle and motor. A friend gave me a used 300watt scooter with everything but the batteries. The current setup is...

Planning on stretching my cart about 18" or so... Question, its got a standard tube frame, can I just cut off the front and slide a solid rod (with OD matching tubes id) into the frame, then slide a new front end over it as well? My plan was to drill a few holes every inch or so in the tube in...

Kinda bummed I cant seem to figure out whats going on, but could really use some debug help.. Short story: -previous working setup, 6 12V 19AHr batteries from Chrome battery setup as 36V 200A Kelly controller 2000W 30yr old golf cart motor I was getting about 30+ min of runtime with juice to...

hey everyone, mostly I hang out in the electric section and started a thread on my planned build since its an electric Kart. But just realized that minus the engine, everything else is relevant here as well. Im mainly trying to get ideas from those who have done ground up builds to ensure I dont...

Thought I'd make a thread just for my build im thinking of starting. Havent been to active on here lately, just so much going on with 3 kids... Attached is my current Kart, bought it used and modified it for electric... It works fine, uses a 2Kw 30yr old golf cart motor and 6 batteries...

Any reason I couldnt use one of these to reverse the current direction through the Armature of the series motor to obtain a cheap manual reverse setup? http://www.ebay.com/itm/100-Amp-Disconnect-Knife-Switch-100A-Two-Pole-Circuit-Breaker-Backup-Generator-2-/170881623181 thanx Danny

Not much time around here to do all the mods I want, but slowly and surely Ill get there... Heres my latest: Originally I had 4 batteries rigged over the back axle (not very well either) This put a lot of my Karts weight over the rear tires making steering and drifting difficult.. So I chopped...

Had some fun with two of my kids today... Lots of leaves on the ground to help counter act all the weight in the Kart :) http://youtu.be/_nkjBMuwDlo Ending up blowing the 60A fuse on the batteries right at the end.. luckily I always carry a spare or it would have been a long walk home with two...

Do they make Locking hubs that would work like older 4x4 trucks? Meaning, I could reasonably-quickly switch my gokart from a dead axle to a live axle setup? I know a simple way is to remove the axle key, but without bearings its probably not a good idea... thanx Danny

I currently have a larger two seater kart and a small (offroad modified) minimoto for my daughter. Neither have any suspension. Mines not to bad due to its size and larger, under inflated tires. Hers on the other hand is a very rough ride since it was design for the track... Im lookig for a...

trying to pick out what size gear to buy for my jackshaft, and at $20 a piece, i dont want to buy multiple :)... Gokart is powered with a 2kW 36V motor and runs 16" rear tires... Ive heard 6:1 is a good ratio, but is that for electric too, or just gas? With my current gear available I can get...
