Hi everyone! I'm going to put fuel injection on my bike (Zxr400) but the articles about it are almost zero and all of them quite general speaking. Has anyone here done this mod? My biggest problem for now are throttle bodies. Hope to have put the topic at the right place. Thanks all in advance!

I'm intrested, what problem are you having with the throttles. 636 should work fine?? I have a set and plan on going FI

It's been attempted, and the reason why there is no documentation is because it probably didn't work.

The easier thing is to put a blade 900 engine in rather than fi

Finally after a long research, cnc parts production, modifications and faith we are on the final straight to finish our project! The bike has alrerady working and we are missing some cosmetic details and of course the ecu reprogramming! the donor bike was a z750 gen1 and that was because this was the one with the correct TB's for our project 34mm). Here are some pic during the process.

Any updates on this? How did it run? any benefits? are the rotors and Cam sensor available on the market?

Hi, I don’t have time due to work to finish the project but I’m planning to take it for a first run this weekend. I think about the ecu remap I will be able to do it next month. The rotors is not for sale yet but if everything goes to plan I will make a full set of the injection mod at the next 3-4 months.

Love this, your bike looks great bro. I've only just started with the wiring and am in need of the pickup and cam wheel still.

Wish I could say I was the first🥲

I would be happy to help you in anything you probably need and also to share your project here!! Pick up rotor and cam is a bit confusing due to the different positions of the sensors so keep this in mind. I didn’t manage to finish mine due to work but I believe until mid February I will take it out for a run. For sure I will update until then the post with more details!
