" Can you point me to your documentation for the Domino? And what documentation you're using for wiring the Curtis?

See this:
http://curtisinstruments.com/Uploads...638E_RevC3.pdf

page 6.

Throttle HIGH is pin 15
Throttle WIPER is pin 16
Throttle LOW is pin 18

According to this:
http://electricmotorcycleforum.com/b...p?topic=5252.0

you have White is Throttle low, Black is throttle wiper, and Blue is throttle high.

Have you tested the throttle with a multimeter?


Are you sure you have the motor phases in the right direction? If they're backwards, it won't align with the encoder, and could spin out of control. "

I do not have a programmer handy but it did work with a another potentiometer with a three wire with a high, middle and low connection. I did not try with the domino throttle earlier "

What pins are you wiring the throttle to on the sealed connector on the Curtis?
Pin 15, 16 and 18

If I want to do a 2 wire throttle what pin should i use? Domino has a two wire configuration also. They also have two wire for microswitch. I dont know what that is for though. "

" has any one used the Domino or Magura throttle? I wanted to know the wiring with Curtis 1238. I wired it up yesterday,
- white throttle wire to pot low on curtis controller (Purple and white wire)
- Black throttle wire to pot wiper on curtis controller (Yellow and white wire)
- Light blue throttle wire to pot high on curtis controller (Black and white wire)

When i turned on the switch the motor just went high, even when i twisted the throttle the motor did not slow down. I tried reversing the pot high and pot low wires but still the same. "

chdfarl created the thread Used Zero 75-5 FX motor.
" Motor was bought last year off of Hollywood Electric to use on a project but never used. It was pulled from a running FX and appears to be in good condition. It looks like they were planning to ventilate it as it is marked in ink but has no holes. It's still in the box that they sent it in 15x14.5x11 in. 35-40 lbs. that it'll be shipped in. Shipping would be the actual price from Dartmouth Ma. 02748. $660

I might be selling a Sevcon Gen4 from a Govecs scooter too. It's in great shape but is UVW so you'd have to replace the encoder. RLS is the OEM and has an RM28 UVW encoder that is a direct replacement for the stock RM29 sin/cos unit on the motor. $250 shipped to continental United State

" Hi

A bit of progress at least one that is sort of visible...
No, i have not been lazy altogether, but most time has been spend for further researches.
For unlikely being able to source any leaf cells, i guess i will go with Lipos from Alibaba for lack of alternatives...
Think i will also go for a Kelly controller with the Me1115 for lack of anybody around me albe to help programming the svencons..

Anyway, managed to get the main attaching points into relation to each other via simple jigs, at first, and transfered them into CAD.
A milled out leftover wooden panel proved my drawings to be almost perfectly accurate. Just a single bolt needs to be moved by say 0,5mm to fit perfect.
Also included the motor axis as an aproximation and some paper cutouts to get an impression/ feel of how to use the avialible space.
Pics may look as the lower battery would not fit into the fairing but that is just caused by the angle of which the pic was taken.
Next i will cut some foam for simulating a bit more three dimensional..

" thanks for the tip Richard, i've just installed the 2nd one, straightforward little app, i'll give it a try next week-end.

I wonder how accurate the GPS is for this kind of measure though, might have to repeat the measure a couple of times. But hey, its' free

thanks "

Richard230 created the thread Smart phone Horsepower measurement apps.
" The July issue of Motorcycle Consumer News contains an article discussing dynamometers. In a sidebar to this article they review a couple of smart phone applications that they say will provide an approximation of the horsepower and torque, along with some performance statistics for your vehicle, just by performing full-throttle acceleration. Attached are photos of two of the app reviews that sounded interesting and potentially useful for a motorcycle owner. "

" Has anyone else made any progress as far as controlling this motor goes?

This motor would be perfect for motorcycle conversions once someone figures out how to control it with a readily available controller or builds an affordable controller for it. "

"This is a 21700 cell (21mm diameter x 70mm length) that is an incredible performer, running over 20% longer at 30A continuous than the Sanyo NCR20700A thanks to its incredibly low internal resistance of 10-12mOhms. This low internal resistance reduces voltage sag, letting the 30T run for longer before the voltage drops too far.
As is typical for a Samsung cell, I consider it to be underrated due to it running cooler than others at its factory rating. I am rating this Samsung 30T at 40A and 3100mAh. Its maximum vaping amps (MVA) rating is 60A, limited by temperature."
I really hope these come out at a reasonable price next year, I'm looking at a budget of around $3000 for the batteries, might have to stretch that though.
As for place under the Busa tank, I thought I could use it as a cover for the Curtis etc. Make a aluminum tray at the top of the frame to mount all the electronics on, not looking to put much weight high of the center of gravity, Like you say though the Busa has a big frame.
I emailed and called a Bill Ritchie at HPEVS the other day and his recommendation would also be the AC-23 with the 1239E @ 144v or if I can fit it the AC-35 with the 1239E @ 144v

So I'm going to size it all up in AutoCAD. "

Some around here have managed in the region of 0.06kWh/km but I can't imagine that the sort of riding it takes to achieve that would be a whole lot of fun () and particularly not on as big a beast as the busa.
