US$600

so how much is the engine that you will stick it on worth?

still havent sorted out that battery issue too well... bit silly isnt it, spending all that cash on EFI just to have a generator strapped to the wheel, isnt it?

that pump draws 2 amps... doesnt sound like much but it is when its coming from a bicycle dynamo.


and for what gains?

still have to replace the coil, thats fine... but then you have to figure out a new magneto using a separate trigger coil to drive the ECU/CDI.

how does it know when to trigger the injector if you dont? yep. crank angle sensor of some type required.

mmm, 28mm throttle body on a 16mm port... excellent for high flow and power, of course.

how to stop the O2 sensor getting gummed up with carbon every five minutes? these are meant for 4-strokes, they arent setup for oil burners...

the option is there though. make the investment, post some pics

If I was going to do something overly expensive with electrics it would be a hybrid (front wheel motor that charges it's battery during ICE mode).
If you want better mileage you can always pedal. Pedal while motoring if you get the ratios right...

Good point HS it seems a tad expensive for benefits, it could be used and would be pretty cool but getting everything to work on a 100$ engine would be quite tricky
