1981 Kawasaki KZ440

45 MPH (72 KPH)

45 mph — 52 downhill, 40 up big hills.

Household blackout protection.

I have a salvaged 48V UPS. It can be used to charge the motorcycle OR convert the DC

battery power to AC and back-feed it to my house. I can run my whole house from the

Below are notes from the project, in chronological order.

Just getting started on the project. Very excited about it. I hope I can get far enough

done to ride it once or twice before the end of summer.

Everyone I have contacted through this web board has been great!

I built a camping trailer from scratch last summer. What fun! The main thing is just

to find other people who are into cool stuff like this!

6/6/07 — Got to work on the cycle a bit the last couple days. I made a motor mount

plate from some aluminum scrap plate I found and mounted the motor. I am

canabalizing the batteries from my electric bike for now to get the cycle to an

experimental mode where I can just make it go for as cheap as I can. So, I am

starting with 3 — 18 amp hour sealed lead acid. I know that won’t make a motorcycle

go far, but I just need to go down the street for testing.

I ordered a 72-tooth rear sprocket from Sprocket Specialists about a week and a

half ago. That’s supposed to show up tommorow. Then I should be able to mount

the chain and make the tire spin.


Just tested it out. Went 4 miles altogether — goes about 35 mph. Only set up on 36

volts with 18ah batteries. I don’t have turn signals, breaklights,headlights, etc yet.

Also the front brake drags a bit.


6/15/07 — MREA Energy Fair (

Took my cycle up the the Midwest Renewable Energy Fair. Had a great time showing

it to people. I was the only one there with a DIY project. Lots of expensive hybrids

and other vehicles out of my price range. I still have less than a grand in this whole

So I figure I have an 8 mile range on a full charge on my current 36 volt

Reprogrammed controller. Changed the throttle response — much smoother to pull

away from stop signs — less touchy. I also activated the High Pedal Disable and set

the max current output to 66%. That should make it so I can’t pull over 200 amps at

a time from the batteries — hoping that makes it harder to accidently burn out the

controller or motor. Still has good acceleration and same top speed.


Just got the title and registration in the mail. It is registered as a street modified

Hobbyist Vehicle. Hobbyist plates are only purchased once. You don’t have to renew

them every year (saves $$$!) Only drawback is you can’t drive vehicle in January. I

don’t see this as a problem.

Got to work on the cycle a fair amount this last week.

Installed a speedometer cable. Cut out the bottom of the gas tank. Wired up the left

hand brake(rear brake) so that it activates the tail light. Got DC/DC converter

working. Wired oil light in tachometer to now show accessory power and brake light

on dash to activate when tail brake light does.

Installed cigaretted plug for other accessories.

Went to DMV and got my Motorcycle Temps.
