Small Engine EFI Kit

In the countless hours I have spent wandering the far corners of the internet instead of sleeping I have stumbled upon this EFI kit and was just wondering what the more experienced people here on DTT think of it even. I have a CB360 and was just looking at EFI stuff for fun more than anything but it would be an interesting deal. Anyways here is the link http://www.ecotrons.com/Small_Engine_EFI_kit.html
 
A design team I worked with in college bought one of these. They're pretty damn cool. We put it on a Suzuki DR200 (200cc single cylinder dual sport). It worked pretty well and we were able to get the bike running on our first try with the kit. It didn't run well because the kit self-tunes but it worked. The guy who owns eco-trons is a bit of a flake and isn't the best with customer service.

My thoughts on the kits are: give it a shot if you've got the money to test it out, but don't expect anything from it.
 
I wouldn't really like the complete kit, but I'd rather be able to buy the components individually. It's something I've thought about quite a bit, and I and planning on using MegaSquirt on my Karmann Ghia when it's ready.
 
The problem with EFI on a CB360 is not the component issue. The darn alternator does not put out enough electrical current to run a fuel pump...With a 9 amp capacity, and pretty much all the amps accounted for with the ignitions and lights, there is nothing left for a pump.

If you can come up with a higher capacity alternator (Sonreir, I believe, put 2 rotors on his), then you might have a chance. Ricks Motor sports only adds 20 watts to the anemic 130 watts already there, and that assumes full strength magnets in the rotor. Those magnets lose capacity over time too.

Still, I'd chose a motor that had better electrics to start off with....
 
Ya I figured that was the biggest issue I had talked to Sonreir about his set up and emailed ricks about their stuff not looking promising as you could have guessed maybe ill just have to figure out how to steal an alternator off a car and make a belt driven one hahaha
 
Don't need that much, but if I had the machining capability, I'd get an alternator from a more recent bike and adapt it....something with a field controlled alternator, not PM.

So if I have access to someone with a lathe and a mill it would be a "worth while" endeavor to buy the flywheel and stator of like a cbr with fuel injection and try to adapt it to my 360.

There's the mechanical part and electrical part. You have to have more than just the tools.

Even Sonreir is sorting out the electrical aspect. It's not as easy as it looks.

Most alternators with field control are dry systems. The 360 is oil bath, so you would also need to develop a crank seal

Everybody drives a car, not everyone droves in a NASCAR race.

Because of the nature of your questions, I assume you don't have all the experience and knowledge yet to take on designing a charging system for our bikes.

I don't think EFI is anything at all cost effective door cb360.

If you are doing it to learn, then it is tuition cost, in the end you still have a cb360 that no one else can fix or troubleshoot.

It would be to learn I figure the best way to learn is to do it unless you really have someone to teach you which I don't for the most part also thats why I am asking these questions most of this is more just out of curiosity because I don't have the cash for it. But I do appreciate the information you have given me. And yes I would agree that EFI is not cost effective for these bikes :'( but it would be neat haha. thanks again
