"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.
Would this work on a bmw k75 3 cylinder. Its already an efi but id prefer to have tunable ecu with more fine tuning. And ad a better air flow meter and a couple of other things that need improvement
Nah you can just draw up your part design in CAD and send it in xometry to have it machined. Or you can take your drawings to a local machinist to get a quote.
@@edgarlira9595 yes it will work if you put in the work to connect everything correctly
A one-cylinder version? 125 to 250 cc four stroke?
(Have machinist training, plus have done sand-casting. I have machined My castings at home.)
Well realistically most older bikes share common dimmensions with the fi counter parts, with some careful planning you can make it easily work. Most conversions start with first understanding all sensors, mechanics, and have a rudimentary understanding of how an engine takes inputs and sends outputs
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
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 🙏🏻
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!
I'm blown away, you are awesome sir. Thank you for publishing.
cool project! subscribed straight away! cheers from Italy!
Dood! Thx for posting! This is awesome, I love this set up and Speeduino rules!
A full day after watching this video still thinking about it. Such a cool approach
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!
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
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.
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, 🙏
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.
Great job ! Best of luck with this project. Sure wish I had the talent to do the same with my bike.
Thank you for the video. I want to install a gl1500 into a car for nice sound and the size being good for a tiny 4 cylinder engine bay. I wanted to make it a twin turbo but I was told it needed to be converted to efi. I have no mechanical knowledge so seeing what you used will atleast give me a place to start. Very detailed. Thanks
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.. 🙂
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.
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.
That's some very useful information on those TBs. Thanks for sharing!
Loss of "magnativity" is referred to as degaussing, love the video.
Curie temperature
In physics and materials science, the Curie temperature, or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can be replaced by induced magnetism. Wikipedia
Magnetism?
I'll need an umbrella to go outside because of the rainedness. All in fun. Sometimes the words hide when you need them the most. Excellent explanation on how to convert to FI though.
I am doing research to convert my kz1100 to an efi/turbo setup. This is very cool.
In case others here are interested. The earlier Triumph T595 and 955i have a Magnetti Marelli EFI system that is extremely simple and can be tuned with free-software. It is alpha-n and it works well on a variety of applications. I even have 2 of them running on a 6 cyl Porsche.
This guy is next level!
Great content, subscribed immediately and will check the eagle files later today!
That was Awesome!!👌💪
This is inspiring. I've had a late 70s XS750 I tore apart for a couple years ago. Might take a stab at doing efi on it now.
I love how much the speeduino has opened up modding like this, made it way more affordable if you fuck up too.
I want to build one and learn how to tune, but I need a platform to test it on. Something small but preferably with 4 wheels so I can tune on the road.
Just earned a new subscriber!!!
I've got a old carb speed triple thats going to be getting rebuilt soon!!!
This got super exciting when you mention your ECU is Speeduino! Thank you UA-cam algorithm! Anyway, cool project I will definitely follow your progress and go through your video library. Thanks for sharing.
speeduino isnt very good. at anything.
@@DieselRamcharger What would you recommend as an alternative? Megasquirt? Something else? tbh i'd like to get as low-level as possible, just for fun to learn more about engines.
@@cannaroe1213 at that price level megasquirt is a similar solution with a much more developed user base. if you want a car with efi to just go fast id go megasquirt/microsquirt as minimum viable. if you want to develop efi system themselves as a hobby then go speeduino. lots of choices out there just gotta decide what you really need. no use paying for a box full of drivers or features you wont use. i picked up a MaxxECU mini for a recent project. seems pretty decent, very compact. good 4 cylinder box for around same price as a microsquirt..but with 2 more injector drivers which is nice.
This guy is a frigging genius 😍
Great job, love the detail. Any more info on the optical sensor you’re using for the crank trigger? Can’t wait to see the rest of the build.
Little tip, the XS850 triple got an oil cooler and you can retro fit it although given the amount of work you’ve put into this project I’m not sure knocking up an external oil cooler for the 750 will cause you to break a sweat!! Lovely to see the XS750 as the base for a major project. 👍
Always rather liked the XS750, not a sports bike but a good working bike. Might look for one to go with the XJ600 ( another good working bike).
Nice job! You can add blocking diode on TX line between arduino and bluetooth module to keep bluetooth and usb active all the time.
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
All the early OEM EFI systems used 8 bit controllers. The first Megasquirt system which was out in 2001 used an 8 bit micro, as did the VEMS system that followed it.
@@ferrumignis Interesting. I specifically mentioned Suzuki though because I worked on them and taught F.A.S.T. so I'm much more familiar with Suzuki systems.
I had various information by Bowling and Grippo when Megasquirt came out and was completely DIY but lost it somewhere over the last 20 years
@@ferrumignis thanks for letting everyone know 😂😂🤣🤣
@@donuts_are_good Err great, glad you are happy?
Loved this.
This was a helpful video I have a 76 gl1000 I’ve wanted to do the same set up on
Check the NGW forum, there have been a few conversions
Interesting, great genius project thanks
I never got to finish repairing the XS750 that was the first bike I ever had.
I had ideas and aspiration, but never got to do anything with it.
Many years further down the line, I've had a couple of sport bikes, and sold them as well.
Now to find another bike project, something cruiser or touring oriented this time!
great work, nice idea on the adaptors also, what do you use for ignition coils?
Awesome stuff. Once I get confident enough I can ditch the generic speeduino I have and use yours
Nice work sir!
Good Worked, Thank you for your designed , I will ordered PCB according to your Eagle file , It looked very robust.
I have my fathers old motorcycles. One is a carb Valkyrie that was favorite touring. The maintenance on this thing due to the ethanol gas mixtures is just brutal. None of that Stabil stuff seems to work. First two times carbs needed to be rebuilt I paid Honda. Last two I did it. The final form is I just disassembled fuel system and left it off. The plan was I would just put it back together when I would ride. An extreme winter storage setup. Except I still have put it back together for two years.
Great work! thank you for explaining the details of this process. Do you have a site that links your boards and project progress?
Far as your reluctor wheel for the sensor you could take the body the board of the sensor and create a casting and submerge it in epoxy with your harness already on it and that will reflect the heat from transferring to it
This was fascinating, thank you.
I have a 1981 xv750se, and the ignition module is kaput. I have been looking in to converting it to electronic ignition, so doing fuel injection at the same time just makes sense. I'm also quite keen to give it a go, as according to the forums, efi is impossible to do on the viragos.
Great idea on using the tachometer drive for the crank position sensor. I hadn't thought of that one. Won't work for my bike, but that's a really good idea.
Thanks for the feedback! I hadn't heard that Viragos were "impossible". To me that says you have to try it! Good luck and if there's anyway I can be of assistance, feel free to message me on Instagram.
@@bombshellbikes1559 Thank you, I really appreciate it. This might give me the kick to actually get going on it.....
DB style connectors can be purchased with SEPARATE pins and sockets. Crimp the pin/socket to the wire and then insert into the shell. I have made 100s of RS332 cables this way. Admittedly, they were not subject to high vibration but the correct hardware keeps the shells together and there is sufficient friction between the gold flashed pins and sockets.
You earned my sub. And i'm not even into bikes. Awesome information
Really impressive stuff. I'm just getting into messing with speeduinos (no2c board) and like yourself I'm not keen on the IDC or molex connections.
Your board solution looks awesome, if you are willing to sell and post a populated board to the UK I'm very interested. Keep up the good work
Sure, I can throw one together and send it across the pond. I am still waiting on some more connectors, so it might be a little while. Message me on Instagram for details.
@@bombshellbikes1559 Yea, same here. I'd love to build this all myself, but I just ain't likely to have the time for a ground up build.
Would love to get ahold of a built/mostly built box.
That said, you happen to have any TB recommendations for an old 83 GSX 750? I've given up trying to find carbs, already have a wideband anyway. FIgure I"ll probably dump an old liter motor in there, and if i'm going through that trouble, might as well be injected.
u r a madman!
I don't work for or even know the prople at Caswell Plating, but as a (now retired) motorcycle (and automtive line) mechanic, I strong suggest you check them out. The "Kreem Alternative" they offer is also so much better, it is used MORE in manufacturing than as a "motorcycle" or "car restoratuon" product. It is used as potting for electronics, among several other applications in large manufacturing facilities, because, unlike other "designed and patented for a single use" (car or morotcycle specific) formulations, this product meets the more stringent standareds of manufacturing industries all over the globe as well.
So, yeah, you CAN beef up the (28 awg) wiring on those smaller connectors by joining each of the little leads to a piece of stranded THHN with a good solder joint, then just pot it with the same (clear) stuff you can also coat tanks with, and it's CLEAR, not WHITE. One product, several uses, less overhead.
I mention this first because - the connectors you discussed moving to (toward the end of this video) are - well - their huge, so, not really great for a clean looking build, and could even CAUSE problems in a lot of applicarions, because they're so bulky.
So, you can pot electronics AND seal tanks with the same stuff, and it's bad-ass.
Ahhhhh, but wait, there's more. The name of the outfit is Caswell PLATING - because that was their FIRST patent. A small plating "kit type" product for short-run products, proof of concept and/or prototyping stuff, AND for auto/motorcycle/antique/collector type stuff. They also have pantented anodizing products that I've not personally used, but have seen the results of others, and have recently seen a UA-cam review about, again, with great results
You've definately got the goods, and this video alone is a great contribution! I think this new-fangled "fuel injection" and "computer controlled engine" stuff may actually start to catch on. I'm not so sure about all this "turbo fan" stuff though. Does that actually even DO ANYTHING? {snicker}
Thanks again for taking all the extra time to film and sequence everything and offer a well thought out overview to this project. Well done, and encore!

ooh....Reeeeeallllly been wanting to add EFI to my 1994 Ducati 900. I can source throttle bodies from the same engine in later years so this might be "relatively easy". I hadn't checked lately on ECU availability for DIY EFI....love it!
wow this is like next level Allen Millyard type of stuff, way above my pay grade but i enjoyed the video even though i know it's something i could never pull off, heck i can't even figure out how to convert my xj650 to a different carb so i can get away from the dang hitachi carbs....good video....
Great info, thanks for taking the TIME to create the video and post. A couple quick questions. What kind of housing did you end up with for the Speeduino? I'm also interested in your solution for the EFI fuel pump, external or internal, small custom tank for the EFI pump, ?? Thanks in advance.
nice, I followed a guys website from back like 2005 He converted his yamaha XJ/S1100 to fuel injection with megasquirt and GSXR750 throttle bodies, I always had intentions of doing it and turbocharging my bike. (Stan Hutchisons XJ1100 EFI project)
I am contemplating converting my Polaris 500 Scrambler '06 model ATV to EFI. I was looking for "kits", but your idea of adapting from other bikes opened a whole new window of opportunity. Instant sub! One question: do you need 36 steps in the crank sensor? The kit I saw just spliced into the existing magneto which is one pulse per rotation. Also, any tips for where I can get single cylinder throttle body to suit my motor? I won't be doing any turbo. Thanks!
Awesome video! Thanks for taking the time to do this.
Quick newbie question. What is the cam timing used for? I assume you only really need crank position for spark timing. Is the cam timing for separate injector timing?
Sorry for the dumb question.
Definitely like what you're doing that vintage motorcycle I have a 50cc scooter that I upgraded the cylinder on in that and would like to put it to fuel injection instead of dealing with a carburetor to maximize my Powers torque and speed
A properly set carburetor will make more power than EFI. If you cant fix a single carb engine, go back in the house and watch t.v.
@@minnesotabymotorcycles4773 lmao lol. I upgraded mine to 88cc and smacked a 125cc efi on it and it runs amazingly. If you cannot take apart a 50cc lol, thats kinda stupid indeed.
You Sir are very impressive.
You will need a large volume plenum between the compressor outlet and the throttle bodies for a three cylinder engine. This is to reduce the pulsations in the inlet tract. This is not required for four cylinders or more.
This video is awesome. I have a single cylinder bike that I designed and built for miniGP racing using a 190cc Daytona Anima engine. I'd love to switch it over to EFI. Would make tuning for different track conditions much easier. Having never looked at a Speeduino before (nor programmed any efi, but with experience programming PLC's using ladder logic and structured text), I wonder what other sensors could be used. Different maps based on gear position? Different maps available and swappable with buttons on the bars? Accelerometers, lean angle? Use it as a data collector for things like brake temp, suspension compression? Interesting potential here.
Hey man, cool build! If you wanted to easily add an oil cooler, you could install a stock one from a '80-'81 XS850. It will fit right on. The only difference from the XS750, is that it has a collar that goes in-between the engine and the oil filter. This collar let's you attach the oil cooler.
I'll have to see if I can find one. I was considering making a sandwich plate to both add an oil cooler and convert to a spin on filter.
Hey, I'm working on a DIY STM32 ECU to convert one of my old dirtbikes to FI and came across your vid during research. Looks like you made some great progress. Good idea on the smart ignition module. I had no idea they exist, and it saves a lot of complexity building a CDI circuit into the ECU. I'd love to pick your brain more about this project. It's so hard to find info on ECU building.
BTW, your optical crank position sensor should work, but the infared LEDs they use have very short lifespans at high temp. This is what makes reluctance sensors more popular.
Yeah, I am a little worried about the optical sensor. I'm shooting a video this weekend covering a new project that is going to hopefully be my proving ground for an optical sensor (this one will be a lot easier to change). I really like the idea of STM32, but didn't want to deal with all of the 3.3 volt level shifting. If you have questions etc, feel free to message me on Instagram (link in description)
Best Board I have senn till now. + the size and conector. I would lovely buy one of those if you would ship to germany.
Los archivos de la pcb estan en la descripsion
Look at the first link in the description
Nice video mate, busy with a similar project as well, er650 throttle bodies onto a kz440 with a microsquirt, only issue atm is my three wire IAC that the micro squirt doesn't accept, just a though I hate to see your grub screw ding the throttle bodies, I drop a captive ball bearing in there to protect the body, Please keep us updated on this beast!
I'm using 2 x sets of these exact throttle sets on my old Datsun 6 cylinder and will run a Haltech ecu.
Picked up the throttle sets for $100ea off ebay 👌
Nice video.
I made the same style of sensor for a "TDC" signal , on a V12 and drove it off the end of the cam with a spacer and an alloy cutter wheel..
I used a Crane optical sensor as they are designed to live in an automotive distributor , that was 20 years ago and it's still running happily...👍🏻😉👌🏼
I looked into several of the actual automotive sensors, sadly the ones I found were too big to fit inside my crankcase cover.
@@bombshellbikes1559 the Crane XR700 SENSOR is the smallest I could find.. It's only about 8 or 10mm high , and the base has two small mounting tabs with holes..
@@panosgamithis8868 I just looked that up, thanks. You are right, that one IS tiny and cheap enough to give it try. I appreciate the input!
@@bombshellbikes1559 You are very welcome..👌🏼😉👍🏻
@@bombshellbikes1559 And subbed..👍🏻
Saw a youtube vid of a guy who put 3 cylinder Triumph injection on a GT750 2 stroke triple and it worked a treat.
amazing!
Love your video! I am looking for some help getting started on EFI setup on a 1996 Suzuki QuadRunner 250cc ATV. Looks like Speeduino NO2C is a good option. What other components do you recommend to start the project?
Awesome video. How you determine the sizing for the throttle body(s)? I have a Shadow VT1100 (v-twin) I want to EFI with either a single or double throttle body setup.
Nice my kz750e1 has a halleffect ignition sensor and a similar tach drive. Ive wanted to convert to efi forever. Im pretty sure z1000 efi bolts on or maybe a suzuki. The Gpz750 turbo is the oil pan i run for oil cooler outputs. Also the valve cover bypasses smog equip. Those 84 turbo kawasaki's are awsome. Im interested in easy ecu's but waiting for it to become super cheap n easy. I would possibly be interested in buying one of your populated boards. Curious what tuning software u use...
curious where you are sourcing your hall effect and optical sensors? Also I would love to see your fuel pump setup. I am new home made EFI systems, not new to old motorcycles, and not new to EFI.
Thank you for sharing your knowledge, this is a fantastic video and well explained. I have a project YZF750 that uses a very similar engine to that of the XJ750 you mentioned early on. What did you end up using for throttle bodies for that bike? And if possible, could you share your tune for that engine?
I used 2006 ZX6-R throttle bodies (only because someone local was selling a set on CL). I'm not sure about sharing the tune, I'll have to check with my tuner to see how he feels about it. If you're interested in the throttle body mounting adapters, I'll share a link in the description.
@@bombshellbikes1559 That would be great, thank you
Definitely want to see the progress on this and want to learn more about converting to fuel injection
You have my answer! I have a Frankenstein project I've been working on and the stock CDI system is crippling it. I need to learn what you know!
Magic 👌
nice. keep on!
1) what did you select as your new piston ring gap?
2) did you make sure to set your induction plumbing to at least 2x the displacement of your engine?
3) maybe consider a water 2 air cooler, they are more compact than air 2 air coolers.
4) does your ECU have provision for a thermocouple for a pyrometer?
5) the ATMEGA2560 has additional serial ports, so you can wire your BT adapter to that.
You’ve done some great work. Which company is assembling the boards for you?
Hi, thanks for the explanation about you Speeduino designs. Did you have to add capacitors on your board to lean the 5V from the voltage regulator module? I like the idea.
@BombShell Bikes can you do a system for an 03 suzuki intruder vs1400?
Hello this is incredible, i am building EFI GSF 1200 bandit. If u could advice me please? The sensor is VR but i am newbiue to speeduino and if should be falling or rising setup chose and also which one of VR sensor cables is VR- and VR+ blue or yellow?
I'm busy stripping my 1994 Honda Transalp 600 for a restore and rebuild. I am contemplating getting the power jet & needle set for the carbs, but if an EFI modification is now doable without too much hassle (which is why it always has been dis-advised by engine experts), I'd really want to give that a try.
Very cool.
You want to run it sequential ?
Hey i’m not sure if you still get notifications but i got an 86 XJ700 MaximX and was wondering the parts list you have for the fuel conversion
Like the through hole black board with a the TE connector . I have arthritis so SMDs are beyond my physical capability . If you have any of these spare for sale that would be great . Running external MAP and Baro sensors incidentally on a Triumph Daytona 675R and yes apart from being a high Z injector very little info exists on these . Sadly I just found this as I have a few sets of TBs spare and would have been happy to trade one for a couple of the through hole boards .
would you know ak it for a bigger ibke like vtx1300 or would i just have to buy 1800 fuel parts and figure out a way to wire the fuel pump ecu
I know this is a couple years old, but would you by chance be interested/able to build a complete speediuno ecu that’s ready to go? I would only need the ecu and appropriate connector and pins. I’ll build the wiring harness myself to suit my own project. I work full time and with side jobs and building my own projects I just don’t want to take on the actual building of the ecu too. I’ve built a few dragbikes with standalones from maxxecu and Holley but want to try out speediuno. Let me know if your interested
I had the 'same bike'- 1977 XS 750. My "maniacs in Canoga Park ,Ca. punched it out to 903cc -with liners. Tons of metal in that cylinder block! I want to do fuel injection on my 1963 'Mailster' 3 wheeler. A 22 h.p. Vanguard motor. so....Thanks!
I noticed the ecu you linked can't be found. I'd like to build one using your setup.
I've got a crf250L it's fuel injection factory I won't to add a turbo was wondering if I can add on a 3 bar map sensor and mod the computer to see the boost and just add fuel under boost and run normal with not ?
I’m wondering if I could do this to my Kawasaki voyager 1200
wondering if you will have problems with the phtosensor with oil in that area, is that a sump area of the block?
robbie in New Zealand , are you still doing this speeduino stuff ? are there up graded boards and the like
My 2002 triumph engine with only 1900 freshly out of the service is now knocking.
Is it possible that the ECU programming cause the engine to start knocking ?
Is it possible that the factory mapping could become corrupt or partially corrupt and cause engine knocking ?
Thank you !
FWIW the reason optical sensors are not common on OEM systems is that it only takes a small amount of contamination to stop them working, magnetic sensors are much more robust. Having been here myself, throttle bodies and ECU are the relatively easy parts of the conversion, what are you going to do for the high pressure fuel pump? Cut the tank up and mount an OEM pump inside? Is the charging system up to the job of the additional load?
I'm thinking of doing a cx500 v-twin efi. Why not just modify the existing carbs to be just throttle bodies? Put the injectors in a tube where they mount to the head?
What I'm trying to figure out is what injectors I can use for a 500ci.
