EFI your motorcycle

This one's In honor of my new project bike. [wildwestsyndey] converted his Suzuki DR 350 from the stock carbs to EFI using the megasquirt EFI controller and a custom machined throttle body. You can find a few pictures of the conversion here. To handle the ever annoying need for a high pressure fuel pump, he adapted an in-tank scooter pump with a machined mini-reservoir to fit in-line with the original tank. For more motorcycle builds, check out the megasquirt success stories forum.

1. megasquirt rules! i'm working my way up to learning enough to install a system in my buddy's car (built for drifting) this summer.
mixing microcontrollers, sensors, actuators, and performance engines is excellent

4. Last year I converted my International Scout II to EFI using a Megasquirt computer. I'm running a GM throttle body and a Ford external fuel pump. Working good so far. Can't beat EFI for off-roading.

5. man, I wish I could have this kind of fun, my vulcan 900 custom is already efi'd from the factory. But I suppose I could jerry rig some sort of a digital handle bar mounted display to show me rpm and speed and oil pressure and all the stuff you normally have in a car.

7. I'd be very interested in hearing what it did for both power and mileage in any vehicle that's had the conversion done.

8. ... goddamnit, looks like I'm not the only one to read EFI as "extensible firmware interface" and not "electronic fuel injection"

9. I don't know why anyone in their right mind would take a Naturally aspirated bike, and convert it to EFI. If your battery dies, you're F'n stranded. Kickstart + NA = Win.

10. @ OmegaForte --> more power, better economy, easier cold start, no re-jetting for altitude or seasonal change, etc. Plus most street bikes sold in the US in the last thirty-ish years and many bigger dual sports rarely have kick starts anyways. So for the majority of bikes on the road no battery == fail anyway. Jump in, EFI is rad.
