    not yet (the bike is still one piece, because it had to be on the road for at least one month. In Quebec, the cost for the license plate for this bike for one year is 1445$!!!!! , so in a week, i'm going to put it in ''storage'', so I will be refund 80% of that price.

    We are hopping to sell the parts for a good price.

    You should definitely play with the elmoto spreadsheet and see what you can do. Here's an example set up that should be within your budget:

    ME0709 motor / Alltrax 7234 kit w/ contactor: $900
    Magura Throttle: $50
    GBS 40Ah, 72V lithium battery pack: $2300 (includes BMS)
    Sprockets: $15-100 (depending on if you need a new rear)
    Chain: $50
    Misc cable and such: $100
    Materials for battery shelf, motor mount, other odds n ends: $200 (estimate)

    Total: $3700 (USD)

    This would easily get you a top speed of 70-90 kph, 40 km range. Way better than scooter performance.

    You could save about $1000 with lead acid, but keep in mind they weigh twice as much. Lithium will last at least 4 times longer, probably more.

    You could save about $700 and still use Li by using 24 Calib 40AH cells (~1300) and the (~300) minibms-24.

    True - but you'd also need a charger. Probably around $300-500 depending.

    Can also look for used motor, controller, charger. I'd stay away from used batteries.

    We decided to go with a 48 volt system, GBS 48 volt 40ah battery pack, and the #2A-C motor/ controller pack from:
    http://evdrives.com/kits_conversion.html . My only question is that the motor will draw 400 amps for one minute, and that the batteries are supposed to be able to give 400 amps max at 10c, so am I overloading the batteries by asking the to perform 100% of their capacity?

    Those cells won't do 400A for more than a few seconds. You don't want to pull more than 3C for a minute, and 1-2C for any longer than that.

    If you're set on 48V, 40Ah cells, you might as well get kit #2C for $200 less. Keep in mind, I think that with 48V you'll be limited to about 50 mph.

    All depends on your budget, but I suspect you'll grow out of 48V very quickly. It's a lot cheaper to just go for 72V right away than to upgrade later on. You save about $150 with kit #4C, add $750 for 72V GBS...$600 and you'll probably be a lot happier. Just my 2c.

    Are second choice is a 72 volt system, with the 4c kit. Are dimension matrix gave the 48 volt 2a-c kit first place, and the 4c second place (1.8 % difference)
    Did you have any fitting problems in your gsxr for the batteries (72 volt)?

    I was able to fit 72V, 60Ah system in my GSX-R...but it's a 93, totally different frame. I believe Coninsan has fit 72V, 60Ah thundersky cells in his 97 GSX-R, so a 72V 40Ah system shouldn't be a problem at all.

    By the way, what's a dimension matrix? Sounds pretty sweet.
