Nice going. I like the meter idea. You now know exactly when to recharge as well :D

Thanks! :thumbsup:

Yup, the meter lets us know what's goin' on inside of the battery (like when to re-charge)
...plus, it shows us what kinda Amps this motors (or (2) motors) are "actually" drawing :cheers2:

Me & the kids did some more (single motor) "testin" :cool:

Here is a video from the (3rd) person perspective :2guns:
(gives a different/better "view" of the kart "in action")

Slight Adjustment

I tried the "upper" function first :thumbsup:
...then, the "lower" one :cheers2:
(probably ~12,000 lbs. of pressure)
...& none of the (HF 90A) welds failed :2guns:

* While I was doin' this procedure, my daughter came out & said "Where did ya get that one?"

I said, "This is the one we we was riding yesterday"
...& she said "What!, why did ya take it apart?" :worried2:

I said "I had ta do some "tweakin", on it
...she shook her head & said "you do too much" :oops:

Sometimes ya gotta do, what ya gotta do :rolleyes:

The back story to the chassis adjustment

I'm thinkin' that when I welded the short "cross bars", in place
...that the "inner" rails got "drawn upwards" a bit :oops: (mostly in the back)

I didn't really notice until I went to mount the second motor
...& it was kinda "crooked" :mad2:

The left side is definitely worse :ack2:
...but, the motor mounted & lined up with the sprocket OK, on the right side :huh:

So, I figured that I needed to "prop" the outer rails up
...& then, apply "downward" pressure onto the inner rails :thumbsup:

I even "overcompensated" a bit by pushing 'em down, ~1" more than necessary :2guns:
...but, they really didn't seem to "move" a whole lot "in the end" & after they "sprung back" :mad:

Um, up next Plan B :cheers2:

Still workin' on "Plan B" :cheers2:
...but, while the chassis was "stripped", I figured a coat of paint wouldn't hurt

So, I "set up" a DIY go kart chassis "rotisserie" :thumbsup:
...the "control/lock" is on the "fixed" side (rear of the chassis)
...& the front is just suspended by some wire

Scuffed 'er up "real good"
...wiped 'er down
...& gave 'er a coat of Jet Black (I've heard that black is the fastest color) ;)
...& then, added a little "pizzaz", to the clear coat :2guns:

* The wife had an old table that had a lot of scrapes & scuffs :huh:
...& she wanted it "freshened up"

So, I cleaned it up
...& made it "bling" too :cool:

Plan B motor mounts

I had some 3/16" steel "custom bent" to use as/for our next set of motor mounts :thumbsup:

Their gonna be about the same dimensions as the first (2)
...but, these should be much stronger
...& more rigid too :cheers2:

The design is gonna be a bit different :cool:
...witch will allow me to "custom fit" 'em
...to each sides, specific set, of "uneven" frame rails :2guns:

After cutting (2) pieces (~7" long) :thumbsup:

I clamped 'em together "bottom side, to bottom side"
...& did some measurin' markin' & drillin' (7/8" hole saw) :cheers2:

Cleaned the holes up, a bit, with a Dremel
...& then, "cracked 'er apart :cool:

Now, we got "twin" motor mounts :2guns:

Nice work on drilling the holes ! Same goes for the Rover.... lots of nicely done holes.

Drilling is my least favorite task, but I got a set of step bits that help reduce my frustration quite a bit LOL

Thanks fellas! :thumbsup:

The holes I drilled didn't exactly line up with the frame rails
...so, I "trimmed off" the inner side, of both mounts (kinda like the "gas" mounts FH showed us earlier)

Yup, that's better :2guns:

Now that we have (2) "rough" motor mounts
...we gotta "custom fit" 'em to their specific "perches":cheers2:

* The "crooked" frame rails don't really affect the axle (much)
...but, they do affect the motor mounts (big time)

So, I sat the chassis on a "leveled" table (just as a starting point)
...then, made sure the axle was good-n-level (that's what we actually need, the motors, to be "true with")

Starting with the right side
...did some whittlin' & roundin'

It took a minute
...but, I got 'er "right on the money" level :wai:


But then, when I "actually" sat the motor on the mount
...it was "way off" :huh: (technical term) :rolleyes:

When I checked around
...I noticed that the motor is not "level", on its own mount :ack2:

So, back to the drawin' board :mad:
...I mean, more whittlin" :eek:

Ok, now I have the (right) motor (itself), "nice-n-level" with the axle :thumbsup:

Next, I "trued' 'er up (left to right) with a "straight edge
...& marked where the motor needs to be, "bolted" down
...drilled some holes
...& then, threw the chain on, just to "double check" :cheers2:

I put a few strips of masking tape on the frame rails before workin' on the motor mounts
...to help protect the paint a bit :2guns:

Dual 48V 1,000W motors are installed
...nice-n-level (with the axle)
...& also, nice-n-true to to each other too (using a straight edge) :thumbsup:

Since each side is "custom fitted" to their specific "perch", I went ahead & marked/stamped 'em (L & R)
...so they cant be "mixed up" :2guns:
