Are you sure the sprockets are lined up perfectly? You'll get a lot of
noise if they aren't. It's hard to tell from the video, but it seemed
noisier than it should be, which makes me question the alignment.

Its chain noise from the roller chain, every time a link hits the
sprocket, it makes a noise, which is quieter with O-ring chain.
I'm using 530 chain (ANSI #50) because it was stock, and easy to get
front sprockets for from surpluscenter.com <http://surpluscenter.com>.
Plus, they've got more options for steel rear sprockets if I need them
at Sprocketspecialists.com
Why are you using #40? any reason? What is the stock sprocket size on
your motorcycle? #40 isn't a popular size. Isn't that 425 motorcycle
chain? You'll need to find a place that can get you chain in any
length you want (because I had to lengthen mine).
Electricmotorsport.com sells 420 and 428 chain, but no 425 (#40).
I'm not all that worried about noise, but it would be nice to quiet it
down a little more. I was more or less explaining to those that think
its loud :)

Travis,
you mention using an o-ring chain to quiet things down. I'm
curious if these are available for a standard #40 chain? I'm also
using a machine chain which seems to work fine. The noise
generated might actually be good for safety. The bike has a shock
absorber in the wheel coupled to the rear sprocket which probably
helps some with the pulsations created by the driven sprocket.

So, another update to my blog this week. A friend (Loni) Has been
helping me with the motor mount. We got it mounted earlier
this week,
and Saturday I installed the motor, front sprocket and the
chain, and
decided to test it out. This is with one 18Ah 12V battery. 80A
when
first spinning up, then drops to around 20A continuous.

Just the video:

The chain was cheap machine chain, and while its not TOO loud,
It will
be replaced by o-ring chain to quiet things down. I used a 13tooth
front sprocket and 44 rear, but have 11 and 12 tooth fronts to
test
and play around with. Right now, its 3.4:1, and adjustable to
4:1 with
the 11 tooth.
Next step is the battery boxes and getting the controller and
charger
finalized. Synkromotive is finalizing the controller, and the
charger
is in the process of getting boards made. Once that is all
together,
we should be running under full non-tethered power.
