from what ive read, 94-97 are the best years to use, but will a 98 zx9 motor bolt up in my 97. i know i need to get a kit that relocates the oil lines or something, and i know you have to grind down one of the motor mounts, but do i have to do anything differently to use a 98? i would be buying the motor, wiring harness, carbs, etc etc. let me know. thanks

Yeah, you'd have to cut your frame apart and have it modified to fit the 98 motor. The 98 is a completely different motor, all the mounts are different, it's physically wider, etc.

Not saying it couldn't be done, just that it is into the realm of heavy modification ($$$). If you were committed to something like that, then a 10R motor would be the way to go! :eek:

I agree with the 10r motor- heavy mods, and unless you have a 'buddy' at a machine shop, your going to end up with a pile of junk- also if your going to build this, realize you are pretty much going to own this forever, as it will be worth little to others- not wanting to rain on your parade, but I have never seen a custom get more than .10 on the dollar, when it comes to selling it.

The ZX9R C model will not fit and is not worth it anyways, Factory Pro claims they can, (through tuning), push more power from the B model than the 98+ ZX9R C model engine. Also the B model transmission is far superior.

The first generation ten motor is not a fit. The heads will clear but the rear block does not clear the frame. I have tried that already.

I have not tried the second generation ten motor and to be honest the ZX10R motor is no longer sufficient, because of the ZX14.

I am going to try a ZX14R engine. Minor mods are no problem, I plan to strengthen the frame anyhow.

I also plan on running stock bodywork paint and everything else.

Sleeper all the way!!

Imagine it, a bone stock (looking) 93 ZX-7R same weight as stock with close to 200 HP.

It will weigh a bit less than the ZX14R

Handle like the ZX-7R

And smoke Busa's all day long. :D

ZX9R Motor

I am fortunate enough to live only a few minutes away from Factory Pro's R&D repair shop and Raul and Otto made my stock 99 ZX7R run faster and smoother than most newer bikes I have been on. Please give Mark the owner a call or the repair shop on advice on more reliable power.
