Electric Motorcycle Conversion
I've owned several motorcycles over the years, and a 1996 Honda ST1100 is my most recent. This thing is a monster, it weighs about 700 pounds and has a gas tank that will hold over 7 gallons of fuel. Shaft drive, water cooled. I've owned cars with smaller engines...
I'm between jobs and decided that since I have time on my hands, now would be a good time to convert the ST1100 to electric. I don't have a garage where I'm living, so I joined the Dallas Makerspace. DMS has a garage area, and one of the members was already in the midst of converting a Fiero to electric. Just after Christmas 2011 I got the ST1100 moved to the garage. What follows is the steps and missteps as I go thru the conversion.
This project is currently on hold due to personal lack of funds.
- Remove the fairings and plastic
- Remove the gas tank
- Remove the exhaust
- Drain fluids and remove the radiator
- Remove the air filter and carbs
- Remove the engine (painful, it is a very tight fit)
- Purchase Motor/Controller kit
- Purchase 12VDC subsystems
- Purchase water cooling parts
- Purchase DIY Open Source battery charger
Next Steps (TODO)
- Complete Open Source charger
- Machine jack shaft for bearings and pulley
- Spec and source pulley and belt drive system
- Build mounting plates and cradle for engine and shaft
- Build battery boxes and cabling
- Build control systems (throttle, regen, instrumentation)
- Build water cooling system
- Convert a gas-powered motorcyle to run on electricity.
- Document the learning process.
- Keep the bike looking as stock as possible
- Take video

CALB CA60FI 60Ah Lithium Iron Phosphate (LiFePO4)
36 cells x 3.2v nominal x 60Ah = 6.91kWh 115v pack
This should yield at least a 45 mile range, possibly as much as 60 miles, with a 20% safety margin.
