From the motor to the jackshaft, then from the jackshaft to the rear wheel. This allowed me to change 3 sprockets to gain the best ratio

Will be lighter when I use aluminum insted of steel
Conversion Time3 months of weekends when it wasn't raining.
Conversion Cost$2750 Cdn.(the duty sucks)for the base bike and a lot of begging to the wife.
Add another $1200 for meters, crimping tools, gear sets, Etc. A necessary evil for fabrication.
Additional FeaturesSince the motor is lighter than a battery, I mounted the motor up in the frame, using the jack shaft to change the ratios is easier than trying to find a larger rear sprocket.
All motor and battery brackets were mounted in the original motor mounting holes. The frame was not modified so I do not need a frame inspection (at a cost of $1500 to check the engineering and NDT (NonDistructive Testing) of the frame). If you can build it without modifying the main frame you should not need to have it inspected.

This motorcycle has been sold to its new owner.
Great fun to ride. I have been stopped at malls, on the street and even in my driveway to ask about it. Even a guy on a new Harley asked if we can trade for a day!

Using a "Kill A Watt" meter on the charger, 2.5 kw/hr at 10 cents/kwh = 25 cents per charge (sure beats the $5 / day for me to drive my car to work)

This bike is now sold to a new EVer.
