Would be curious to see what it does with the velocity stacks and possibly larger injectors. One thing I've been thinking of trying is getting a used set of 38mm throttle bodies from a vulcan S or Versys 650 to add along with the velocity stacks, 2017+ ninjas all use 36mm throttle bodies. I'm glad you posted this video, cause of all the stuff I've seen, I've yet to see anyone talk about the injectors running out of steam on the top end like you've shown. Also you're on of the first I've seen do the air box mod on the 2017+, was glad to see someone do something to open it up more , and then run it on the dyno was the icing on the cake!
Thanks for your comment, that would definitely help a lot to either bore these throttles or replace with larger ones and velocity stacks but have a good feeling that a head port and polish would be a major move along with at least 288cc injectors would do the job nicely. It’s not often I see injectors topping out in a naturally aspirated motorcycle. Should’ve posted a vid of the oscilloscope on the bike was just awkward to hold it and load the bike up so high. Thanks for your input.
As far as I’m aware they are 240cc injectors but please don’t hold me to this I will have to do some research to be sure. If I were to choose a set I’d probably use a set of 2007 zx10 injectors they 330cc the newer zx10s are 400cc. Just have to be sure you use injectors that have the same hole and spray pattern.
@thebikeguru91 I believe older 650s had higher flowing injectors as well. The 2017+ ninja 650 injectors also just look generic with no markings. The vulcan s and older 2016 and below ninjas use EAT287 injectors which seem to be higher flowing. I think the 38mm throttle bodies I'm getting will have those injectors. I guess we'll see when I order and get everything in.
Sounds like your on the right track I’ll investigate best route when client comes back for more mods. Thanks for that info will look into it for sure. All the best with your mods. 👊🏻
Biggest isdue i have is from side you see useless fairingbfrontband wind screen. To.liw all below triple clamp looks like it is saghing. Offers no wind protection orvaero help for rider. Looks stupid also. Top ofvfairing and wind screen should not all be atbtank.level and lower, useless and looks like it is not mounted right. Just my opinion, hate looks of newer spirt bikes design peaked in late 90s very early 2000s
I must be honest I’m also pretty into the old school look that’s why I chose a K4 GSXR1000 for my turbo build. I’m 6”4 so the new bikes so small for me too.
Awesome video, and super happy with the end results. Thanks a lot for everything you’ve done on my bike. Look forward to bringing it back next year
It was a pleasure to tune it. Thank you so much for your feedback.

@@thebikeguru91 Would you by chance know what factory Kawasaki injectors would be higher flowing than the stock ones in the 17+ Ninja 650?
