" hi
fabricated those centering devices - necessary? well not really but it will impress the MOT engineer when making the bike road legal weights next to nothing and will transform a little of that load from the cantilevered motor-mount. Of course it needs counter/lock-nuts with it.
Attachment 7856Attachment 7857

Also played a little with future power cables. some cut offs from an unused garden house serving well for this purpose.
The shown layout will only the most foreward line to be longer than the others by about 1 cm
Attachment 7858

and will just fit into the frame and fairing by the amount of "just"
Attachment 7859

fairing will need some notching to make the sides meet without bulging... but only a tiny bit it already closes with some slight pressure...

bob_piper created the thread Ural 650 custom EV.
" This project is only in the dream phase right now. I'm new to EV conversions and while enthusiastic, quite down in the pocket. I ride a 1995 Ural 650 tourist (one-wheel drive) and I'm waiting for the ICE or transmission to crap out which could happen soon or never with these bikes. For my ideal project I'd create a new sidecar frame out of aluminum with a more streamlined, fiberglass body. The aluminum frame would act as a battery tray so that the weight is evenly distributed and provides a low center of gravity. The 12V acc. battery could stay under the seat where it is and the tank could be cut open to serve as a home for the controller and/or charger. (Would this cause over-heating problems? Is it better to have the controller out in the airflow?) One of the issues with older Urals is that it has mechanical drum brakes which don't work well to begin with. I'd want to convert the front brake to disc at the very least, but if I have an AC motor and regeneration, are the brakes a problem?

As I said, I'm new to this, so I need to figure out what size motor and battery pack I need for decent performance and work from there. "

" I'm new to EV conversion, but I've always wanted to do one. I ride a Ural 650 tourist (one wheel drive.) I was thinking of making a battery box under the sidecar frame that would distribute the weight more evenly and provide a good center of balance for the bike. This would leave more room for the motor and the controller/charging unit could be incorporated into the tank. The nice thing about the older Urals is that they are relatively cheap, shaft driven, and the sidecar frames are fairly beefy. "

" Muther Nature got us again!

We loaded the "new" van with the bike, and all the race gear, drove two hours to the "good" track,
unloaded, setup the generator and chargers, took the bike to the inspector, (all he wanted to do was
ask questions about the electric bike) returned to top off the charge and got out the rest of the racing gear.

We sat around in the heat for another 1 1/2 hours.
5 minutes before the track opened the staging lanes a rumble in the background paused the track prep.

One of the officials stopped by to let us know it was going to rain within the next 20 min. We scrambled
and got everything back just in time to beat the storm.

A hour later they shut down for the evening. It was a 20% chance of rain today....

We will try again on Sunday and the "OK" track. "

" Decision time

The motorcycle (Kawasaki) uses "big 'ol" #50 chain (5/8" pin to pin) & sprockets

My 8kW motor has a 10 tooth sprocket for #40 chain (1/2" pin to pin)
...I have a 54 tooth driven sprocket (that I can use on the rear wheel)
...& I have ~10' of #40 chain too

#40 chain is also a bit lighter

So, we'll go with that, #40 is the winner

Then, I removed the rear wheel assembly, to switch the sprocket from a 45 tooth for a #50 chain to a 54 tooth for a #40 chain

Before instillation, I had to do some DIY machine work, on the driven sprocket to make it "fit" onto the Kawasaki rear wheel

" Hi
working 18 days in a row somehow dampens sparetime or social life somewhat.
at least i managed to fabricate 4 small holders for the controller.
Small steps... well i guess its important to carry on.
Took the craddle out of the bike again , like this its easy to work on it..
Pics show how these holders keep controller in place...
last pic is taken from top down, it shows how the controller plate extends fore and aft of the cutout so basically the controller now can go nowhere.

" Hmmm... Are you using "the Gallery" to upload your pics into? From there, you can copy the link to your pics and they will show up large on your thread. The Gallery is cool too because you can copy a link and post pics on other forums without having to upload the pic again on that forum. "

" I think, I can stuff the motor "up in the pocket"
...mounted right onto the trailing arm

This way the motor & the rear wheel will move as one
& there will be a heck of a lot more room, inside of the frame, for batteries & electrical components

So, now the motor will go where the battery used to be
& the batteries will go where the engine used to be

" Because individual builders need to be qualified at some level, so I like to talk to or email potential customers. If I feel they are building something unsafe then I won't sell to them. Motorcycles can be dangerous and some builders have no clue and wind up getting frustrated and failing and they never blame themself for the failure. Guess I should update the web page

" The pics need to be smaller files because I think of bandwidth. Try to lower the MB size until you find the size that works. You might need to use photo edit tool in your programs. You know, for flipping or changing contrast and brightness or cropping your pics. "

" Resizing them lowers the kB size in effect (for the Avatar pic) or MB size for posting on threads or in the Gallery. If I post from Tapatalk on my cell phone I dont think I need to resize them. I dont usually use my phone though for alot of internet stuff. That is just the easiest way for me on my Ubuntu OS "

" Last summer, I picked up a nice 1980 Kawasaki 440 LTD with a seized engine for $100.00

The guy actually wanted $250.00 because, he said, the carbs were "rebuilt" & worth $100.00 each

So, I said, "will ya take $100.00 CASH & you can keep them carbs, maybe sell them on eBay"

I took 'er home, stripped 'er all down & cleaned 'er up
