We met this guy on a ride today and I thought this may interest a few people here. It's a home made efi computer, BMW throttle body, and GM injector.

 

Sorry I only had my mobile phone camera so the pics aren't that great.

 

Pretty cool. The most direct swap it seems to me, would be getting most of the donor FI parts off a SV650 and the ignition,ECU and some other miscelaneous parts off a BMW F650.

I wonder what he used for a fuel pump? Most FI pumps are inside the tank.

For overall driveability, easy starting and simple tuning (although more expensive) I still prefer EFI over carbs.

 

Very impressive - did it run good? How was throttle response?

I think my only concern with EFI from the factory would be it may be harder / more expensive to richen things up for street legal bikes. There's no reason to think that manufacturers will all the sudden tune the EFI systems for power delivery as opposed to EPA emissions compliance. So like carbureted bikes, the street legal bikes are going to be lean and optimized for emissions. So instead of $20 of brass jets the only option with EFI may be a $350 power commander. I know there are other advantage to EFI, but I'd just be concerned about the stock performance and how expensive it will be to make it better.

 

The efi pump was in the tank. He said it had a few flat spots he was working on but for a POS looking bike it went like a rocket, kept up with the 450's in our group on all but the very long straights.

 

And I thought that nobrakes was going to be the first to have an efi klx.
