Re: 2-cyl 4-stroke bike: injector sequencing without cam sen

Hi all, very glad to get so many questions answered, cheers :)

@EWflyer: Thanks for a great explanation of the difference between carb vs injection, regarding mixture. Helpful picture, very quoteable. I feel drawn to the dual throttle body + 2-injector solution initially, having heard of intake ...

2-cyl 4-stroke bike: injector sequencing without cam sensor?

I wanted to add EFI to my twin cylinder 4-stroke engine, but can't think how injector sequencing could be achieved if there is only crankshaft sensing readily available. It uses wasted spark ignition; would that mean it has to use 'wasted squirt' as ...
