"Convert ANY motorcycle to EFI...Cheap!" -If you're a machinist and have a lathe and CNC. Nice work! My 82 Honda CX500 Turbo was factory boosted and EFI.

This project is incredible, it seems that you also have an incredible amount of knowledge on the subject of fuel injection and turbocharger setups on bikes too so I’m definitely going to follow your journey from now on. Awesome work thank you 🙏🏻

Excellent video, thank-you. With my "engineer" and "safety officer's" hats on, several safety points if you are doing a DIY pressure test on something you have built: 1. Don't test with air or gas. A failure can result in an explosion. Use water or hydraulic oil. 2. It is usual to test at 50% above normal working pressure. 3. Don't forget your eye protection.

Man I love that all the different things are spliced together its honestly amazing tbf
-
incredible work, it blows my mind how much data, and how many parts are available now to build just about whatever you want. I wish I had half the knowledge you seen to have on the electronics side!

Love what you're doing, love the DIY speeduino and the improved connectors. I even love where/how you're mounting that turbo! Would be interesting to see if you could make a cooler to sit between the turbo and intake and do a with/without tune to see what changes. I'd also love to hear how these bikes feel after the EFI swap, like if their mountain performance is considerably better, etc.

I'm blown away, you are awesome sir. Thank you for publishing.
-
cool project! subscribed straight away! cheers from Italy!
-
Love your board layout, I was about to get some 4.3 printed but I'll be looking into your design. It's much more practical for me.

This is very interesting for me, I have a Yamaha XS850, with a set of 900 pistons to be machined, already have Triumph carbs for it, and was looking at Speeduino to see if I wanted to use that for ignition, as it might help when tuning. I guess the full EFI is almost as easy. Think the Triumph 850s and 900s had same carb spacing, so thought the throttle bodies would be the same... Anyway great content and good to know these older bikes are not forgotten.. 🙂

Dood! Thx for posting! This is awesome, I love this set up and Speeduino rules!
-
You are a Genius bro...👍 Your knowledge on EFI is impressive and you make it sound simple... Thanks for sharing bro and will definately follow your work... Thanks again, 🙏
-
Great job ! Best of luck with this project. Sure wish I had the talent to do the same with my bike.
-
A full day after watching this video still thinking about it. Such a cool approach
-
Hey Loved this video, Hope to see an update on how everything turned out. Been thinking about converting my bike to EFI and theres not a lot online detailing the process. Would love to see more content of such content.
-
Man, that's amazing! Thank You for sharing your work, it's a huge help getting access to that Drive. Sorry if my texting isn't so acurate, i'm from Argentina. Regards

Loss of "magnativity" is referred to as degaussing, love the video.
-
When the Arduino came out I wondered if it could be used for ignition and injection system as I knew Suzuki used 8 bit on early ignition systems. Nice to see the 'Speeduino' is out as open source, I'm going to have to look much further into it
-
I can't wait to see more of this! I have an XJ750 that I have been contemplating changing over to fuel injection (since the carbs it came with are so incredibly temperamental and I can't get them tuned right for the life of me) Really love that you are putting the time into showing this all in such detail and love that you are bringing more life to these old bikes!

Gsxr600 throttle bodies from the early 2000s are nice and easy to respace. I used the outer 2 on my XS650, with ford IAC, dubshop modified gm temp sensor, ls coils, and 2" 36-1 wheel on the cam with a microsquirt. Dead times took some playing around, but the stock gsxr injectors are 220cc. The gsxr ITBs fit perfect in the BS34 carb boots from an 80s XS.
