Sry I haven't been here in a while. Way too much going on these days.

I have a 1990 Ninja ZX750-F4. I would like to put a larger, fuel injected motor in it. Can I fit a ZX-10 in the frame?

And secondly.......I am searching for a running ZX-10 motor also. Any suggestions would be greatly appreciated. Even if someone here has one for sale, let me know. Thanks

 

mmm, my first thought says NO to the 10r engine and the F style steel back bone frame. The second concern was the amount of frame flex in corners even with the 750 engine (my '88). Not sure if I would like to ride that with a 10r engine. Just my thoughts, but good luck.

 

Just get a ZX-10 and save yourself a lot of danger and headaches! A 10 motor in a 750 fram would be a insanely dangerous, even if it would fit! It would be simular to putting a ZX-14 motor, in a 600 frame. A frame is only designed for the torque of the original motor, and if you double that torque, something is going to break, or you are going to eat asphalt, one of the two or both!

 

Tanks guys...lol. It was a thought. I just picked up a newer zx-10
