I have 2 bikes, both Yamaha 650 XJ's One is a rider, great condition, second I got for a parts bike. last week I decided to convert the parts bike to Electric. I found this kit that sounds nice, 72 Volt Perm 132 Kit with Contactor. On this site http://www.electricmotorsport.com/PARTS/parts.htm. Not sure what batteries to use yet as it is just a big empty now, but I figured I could use the gas tank as a box for most of the components besides the motor to help it retain its looks and leave space for batteries. Biggest question is can I use the drive shaft or would I have to replace the whole rear wheel. Im hoping I can either use the universal mount connector from the engine directly on the motor shaft or rig up a sprocket and weild the connector to it and use a small belt or chain to the motor. If I can use a belt there would be no chain sound at all when it is in motion. I dont have a website set up yet, but I have been taking picks of it from start to now with the engine and other do dads off if anyone wants me to email some pics like starter pic and pic with engine off etc. Still have the electrical on it and have found LED light replacements on ebay to help save energy.
I am also thinking of deep cycle batteries from optima http://www.1st-optima-batteries.com/ . I am not sure what the packs cost that folks here mention. I might be able to get one of those for the cost of 6 batteries from optima. and maybe it would all fit under the tank instead of using 4 under and 2 saddle bags.
Any help is appreciated, I'm learning fast on this one. Maybe next time I'll try a car conversion. I have a 93 Grand Am that just had engine problems :)
