- This video is a walkaround of my fuel injected Honda CBR250RR mc22 motorcycle project, nicknamed CBR250RRi.
The project started out as an experiment in getting the bike running on EFI using a Microsquirt ECU but over the years has grown into a lot more. The bike is currently running a Life Racing F88R ECU with a completely new wiring harness.

A friend who is an Automotive Engineer & motorcycle mechanic got his Tyga MC22 running on Microsquirt in a matter of weeks about 18 months ago with great success using measurement & mathematics & did cylinder head work & machining to make it optimal for 98 octane unleaded , increased compression ratio modifications were done . We increased valve lift slightly . Race grade top of engine parts were made / used & he raised the rev limit by 2,000 RPM above the factory benchmark which our oscilliscope told us was 16,900 RPM before work began . We had a power increase of about 16-18 % . The friend has completed a second one during Covid lockdown as he had spare time & had extra sets of parts he made & purchased on standby beforehand from the first motorcycle which allowed him to convert my companion rider ( track ) MC22 to the same configuration as his in two days as he knew the procedures .The dyno test was the same for this bike also . He will be doing this to a Yamaha FZR 250 in two weeks .Parts are already prepared & I will ride the converted Yamaha on my birthday soon at the track alongside him riding my Tyga .I am sure the bikes will be fun to compare . I personally like the Yamaha FZR engine sound as it is more raw than the Honda , that has all it's gear driven cam harmonics which cause me back pain after a while riding it . The Yamaha does have EXUP valve installed . I loved doing the first prototype Tyga EFI conversion last year with my friend . It helped strengthen our friendshp &:it was fun & I learned a lot .
(A) where is his youtube user name and (B) he better document the fzr250
@@AdamMc07 He is not a CZcams contributor . The post five months ago described research he was doing as well as the resultant prototypes of project Tyga 22 . He keeps his expertise close to his chest to a certain degree as he had honours at university . I cannot tell him what to share with the wider community . This is his decision , not mine . I had a lady friend convert the Yamaha FZR 250 series workshop manual to English for me a couple of years ago . I have a copy as does the mechanic friend. We had the Suzuki GSX-R 250 books done also . This allows us to do special refining work with a platform to work from . I do not upload anything to CZcams as copyright theft is commonplace & it is poorly moderated .
The Yamaha FZR 250 3LN1 was converted to 98 octane fuel optimised configuration but with standard grade new engine components with the EFI conversion & the Microsquirt system applied . Compression ratio was raised from 12.0 to 1 TO 13.5 to 1 . The same as the two MC22's . I will ride this set-up on Monday 11th April . We have acquired a second FZR 250 3LN1 which is white & light blue which we will refurbish so that I can use it for private transport . It will be handed to me on my next birthday . A cylinder head had to be made up overseas & sent here for some machining to achieve the compression ratio change . The same had to be done for the MC22 Tyga's . This was the reverse of the changes from earlier 1990's MC22 models to the watered down 'R' series of 1994 . The black 3LN1 was upgraded , the white & light blue one for my private use will be close to standard with minor refinements only .
Nice! Sounds like some really interesting projects. If he ever decides to put any info on them online then be sure to link to it. :)
WOW.
I put my MC19 in storage before leaving to go overseas for 6 months... 14 years ago. I'm now planning on heading home permanently early next year and had started to think about what customisations I'd like to make to it (assuming I can get it going and back on the road, of course). You've done everything I had in mind plus a whole lot more!
Your blog looks like an incredible resource which should save me from an awful lot of head scratching, so thank you!
Glad it can be of help. Do share progress on your bike as you go along. I'm always interested in other projects. :)
This must be the only MC22 with an Ethernet connection.
Excellent walk around and project, I can see how much time and effort you’ve put into this. Well done!
Thank you! Its been a great ride. :)
A lot of hours put into this bike, top workmanship! Wiring looks so clean.
Thank you! Yeah I'd never want to tally up the man hours cost...
Great walkaround, countless hours have gone into this MC22. Makes me want to take my MC19 out for a spin
Wow a modernised MC22. I want all of these mods on mine!
Solid build. That dash looks really nice though, it would look even better in my opinion if you got a plate that goes around the cluster, that covers all the wiring 👍
Thank you! I know what you mean but I actually kind of like the wiring there. Its the only place in the bike where the new harness is visible and I'm very proud of my new harness so I don't really want to cover it up. :)
@@twillinger I can respect that. Do whatever you wish. You spent the hours to get that to this stage. So you can showcase your work, and can see where you're coming from. Just my 2 cents.
Amazing.. make it running 💪 you are going to be a hero
Amazing modification
wow i found the thread at a great time, this is so cool man
Amazing work !!
Never seen before injection MC22...
Keep it up!
Looking good Tom. Lot of work gone into it.
Great video, looking forward to the next.
Wow superb broo❤️❤️❤️❤️
Great job
Thank you!
Awesome bike! Well done!
This is amazing
Thank you!
Can you do full explanation about how to fitting fuel injection system and ecu design
Hey Thomas. I'm in the process of buying an mc22. Dont know anything about motorbikes to be honest. it'll be my first bike. Picking it up from a lad in meath in a few months but its in bits. You clearly have incredibly intimate knowledge of these bikes. Can you give me some pointers on reading material or resources to allow me to educate myself?
very impressive.
Thank you!
looks at all those KHWHHEELS!
Very cool
Thanks mate!
Awesome project, very nice improvements. I'm competitively racing my MC22 here in California and would be fond of a Ohlins shock. May I please ask for any info you have on your Ohlins shock to get my suspension builder started. There should be a number on the shock body, or any pictures of it before it went on the bike. Any help is much appreciated, Thanks
A bit late I know sorry! The shock is a S46HR1C1 base. The key thing is that the top mount cannot be aluminium as there isn't the clearance to the frame for an aluminium top mount. Really, I just dropped the bike into the local Ohlins dealer and left them to spec and manufacture the shock how they saw fit. Hopefully you get sorted with yours!
Greetings. On my mc19, the compression is coming to an end, now the compression is from 8 to 9 atmospheres. Tell the guys where you can buy a piston group, rings and more. I saw that they sell Aliexpress on the Chinese site, I understand that this is not Japan, but even so, someone may have experience, for what mileage such spare parts are enough. Thank you.
Hi, doing a 600RR 2007 front end conversation to the mc22 and was wondering the dimensions required for the triple clamp stem did u have to fab one? Cheers
Hi. The only parts I fabbed were the wheel spacers. Everything else fitted with different sized bearings. The top stem bearing was special as the standard size is a bespoke Honda size so I needed to find something with the ID of the Suzuki stem and the OD of the Honda bearing. I did have to cut away part of the nose fairing and false air ducts to give some clearance. More details and photos of the conversion in this forum post: www.cbr250.com/threads/project-cbr250rri.7307/post-294714.
@@twillingeryep just finished the whole process, works great, just needs about 5mm more steering angle to clear the handle bar lock. I’m really interested now in potentially designing a new airbox that uses the ram air ducts on the sides of the fairings but I’m not sure if I should stick with using carbs and if that will work well enough, or take the weight penalty and try and make a EFI system based of yours for it. Should definitely help top speed power with that extra 1psi of air pressure 🤣
Cost a mc22 carburada $$ ?? Saludos desde lima perú 🙌✊👍, excelent video 🙌🙌
I am looking at fuel injecting my mc22 and was wondering what injection manifold and injectors you used for your bike?
Hi Mark. I have used the original carburettors and modified them to take the injectors and fuel rail.
I have a few posts on the process in my blog.

@@twillinger excent videooo!! Thank for inf., saludos desde lima perú 🙌
Close your eyes, thinking this bike is rolling in the streets of, let's say 2060 !!!
Subscribed did it lost the power because of fuel injection ?
I couldn't tell you to be honest as I never dynoed the bike before doing the conversion. I wouldn't expect it to lose power though nor gain any either for that matter.
@@twillinger going efi should theoretically allow you to have better control of the fuelling through a wider rev range resulting in more power and better efficiency- depends how much you tune it though- paticularly if you figure out a way to run coil on plug or similar
Good job lot of work maybe slide carbs would have been easier and better! But maybe that wasn’t the point. Well done ! I built drag bikes.
@@mikepeterson6527 Thanks. Yeah the point of the project started out with learning about EFI and engine control and I've managed that. :)
Hi tom are you irish
Yep! I am. :)
Dont you have the original parts removed from th bike
Hi. Yes I have kept all the original parts. The original plan was to keep the modifications 100% reversible but recently I have not been sticking to that rule. The bike is never going back to stock!
Does it have a v4 in it?
Inline
still use the mc22 engine ?
Yes. The engine is still the original engine.
