Had a small warm spell (like 52*)

Got Arriba out for a quick spin around the neighborhood

Brought the GPS along to gather some speed data

to document how fast she is - currently

(with just the one 1,000W motor)

Here is another Desteny rides video

She has had some steering issues

It seems that

...by only running (1) motor (on the left side)

...with lots of power/torque

...& having such a short wheelbase

...& with the rear wheels being so far forward

...& with the frame being so light


the Arriba kart tends to (with her on it, not so much with me)

...lift the front wheels & lurch toward the right

...& doesn't like to turn left at all

...especially on grass

Spring has sprung

I got the !ARRIBA! kart out

Time for Chapter 2 Dual Motors

I got (2) of the 48V 1,000W motor kits from Alfa Wheels ~$100.00 each
https://www.ebay.com/itm/1000-W-48-V...-/161881812471

These are kinda kool kits for ~$100.00
Includes the motor, speed controller, throttle, key switch & even a 48V 3A battery charger

First, I switched the #25 chain sprockets on both motors with Power Curve sprockets for #35 chain

Then, I removed the left (MY 1020) 48V 1,000W motor & replaced it with a ZY 1020 48V 1,000W motor & I also installed a (matching) 48V 1,000W ZY 1020 on the right side

I also installed a (matching) 72 tooth sprocket & a piece of #35 chain on the right side

The drive sprocket & the driven did not line up
...looks to be ~1/4" off

Used the chop saw to cut some assorted spacers

Then I got 'em all adjusted up

Now we gotta hook up the electronics

Removed, the MY 1020 speed controller, off of the back cover
...installed the (2) ZY 1020 controllers
...installed a 50A circuit breaker
...& the charge port that came with the motor kit

Connected, an on/off switch (on the dash) to each of the controllers "lock" plugs
...a motor to each speed controller (wired so the left one spins CCW & the right one spins CW)
...the (2) thumb throttles
...& the charge port plug

I grouped
...the (2) battery positives (+) together
...& the (2) battery negatives (-) together
(the ones coming out of the speed controllers)

Then, connected a piece of black 10g. wire, to the 2 wire negative junction
...& ran it to the battery packs negative (-)

Then, connected a piece of red 10g. wire, to the 2 wire positive junction
...& ran it to the input side of the 50A circuit breaker

& then, another piece of red 10g. wire from the circuit breaker to the battery packs positive (+)

I mounted the left thumb throttle on the left side of the steering wheel & got it all adjusted so both throttles rotated the same (had the same throw)
...then I noticed (it's upside down)

Both of my thumbs are not on the left side of my hands

Easy fix, just flipped it over

Double checked everything, propped 'er up & made sure that the wheels were off the ground

Flipped
...the circuit breaker "on" (nothing popped or is smokin')

Turned the left switch "on" (still lookin' good)
...& gave the left thumb throttle a twist
Yup,

Turned the right switch "on"
...& gave the right thumb throttle a try
Yup,

Time for a test drive



Me & the kids rode 'er around for at least 20 min or so before dinner
...then plugged the charger in when done

I tried a "Hold on to your Hat" test with the !Arriba! kart

So, just a 48V battery pack, (2) 48V 1,000W motors & a "beefy" switch

"ED BA" "UN DA LA" "!ARRIBA!"

Wow!, just Wow!

I think we should install some "wheelie bars"
...before the battery box disintegrates

But, how "high of a wheelie" do I want to pull/sustain

I set the front of the !Arriba! kart on a tire to check "ride height"
…front axle ~9"

Naw, that ain't enough

How about up on (2) tires?
...front axle height ~18"

What about the battery box?
...looks to be ~ 2" (off of the ground)

Yup, that should work

So, a couple of ~3" wheels should work

Mounted/bolted them to a piece of steel
...so their removable/changeable (if necessary)
& to help keep 'em aligned

The tricky part to a wheel bar is the BAR part. Those new wheels have to extend out at least 2 feet. Reason is you create a whole new "wheelbase" when they are in use. And the rear wheels then become the front wheels. With front wheel drive you have torque steer. And with the rear wheels 4 inches behind you will turn and turn quick.

Also, with them that close, you could very easily flip alllll the way over because now those rear wheels are a pivot point.

Wild ride for sure. Knee pads and elbow as next time. Lol
