SO YES...a 2004-2009 engine fits in a 7 R frame, can you use the original mounts? NO, not if you want it to handle the same as an original 7

Does it handle the same? if you can keep the front end on the ground YES.

Does it twist the frame?...haha....NO, although my frame is SERIOUSLY MODIFIED.

Was it worth the time and effort...oh good god yes.

Can you tell it has a 10 engine in from just looking at it? yes if you know what your looking at, you have to modify the bodywork to have enough clearance for the LH genny cover, and depending on the exhaust you choose, you will need to cut away a little bit off of the lower RH fairing as the clearance under the sump isnt enough to allow the exhaust to clear the body work. Like i say, only if you know what your looking at though.

Here she is after the 18 month rebuild and engineering fun and games. Oh i did ALL the work here in my workshop by myself, the only thing i was uncomfortable doing was the alloy welding, so a mate who welds aircraft parts did it for me.

She runs at 187bhp using a Motec M400 ecu in closed loop, A Motec CDL kit logger dash...well the rest you can see

She was in PB magazine here in the UK this month with an 8 page spread and write up.

Have fun and ride safe






Absolutely fantastic. Any pics of the process? Tell us more.

For your Information, I have copied your post to the zx7r.de Forum.

In Germany was a zx7r sold with a GSXR 1000 engine.
It is also possible to fit it

Very cool build Andy. Thanks for the info and congrats on the write up. Now I need to find that issue of PB.

I can post a lot of info if you really wish, i dont mind sharing the technical stuff, in fact anything to help fellow Kawasaki riders.

What do you want to see?

A good friend of mine, KC at BRG racing has been looking at installing a new gen CBR 1000 engine, i know the Gixxer Thou will fit as well (its not so simple)

But in my humble opinion it should be a Kawasaki motor....it just seems so wrong to fit anything else.

I guess you want to see a lot more detail of mounts and stuff?

Let me know what you need and ill help out

Regards
Andy

A hoot to ride...errrm yeah, i originally was prepping the bike for a fuel injected 950 engine i was working on, so i set the gearing 16F 41R, when i put the 10 engine in i usd the same gearing, that gave me serious air in all 6 gears, it was uncontrollable in anything above 70% throttle, i have the data logs here to prove it....it topped out at 158mph but OMFG it got there sooooo dayam quick...haha, no i got it sorted at 198mph top speed and i can actually now use full throttle in all gears. I have uploaded a little youtube vid for a laugh, where a guy on an RSV Mille really got the hump, the 7X now has full throttle gear shift (Motec of course) as you will hear in the vid, she spits flames and pops like a real animal.....have a listen here, I let Mr Aprilia come past at about 4:45 mins into the video then really pissed on his parade for a laugh, check out his body language because he couldnt understand why he just couldnt catch an old 750 for the last 5 miles (and i only went 70% throttle and no more) and i was short shifting below 10K, there seemed no point in hitting the upper power band of the C2 engine

Enjoy :D

I think, the interesting will be the settings of the holders (the diametres).
The think to fit in the engine in the frame will be the hardest work.

If you have any drawings or pictures of the engine mounts and locating the engine in the chassis that would be awesome. awesome! Pictures of that beast naked would be very cool too. Thanks.

KC tried the CBR motor on one of my L frames. Not even close. Back to the drawing board.

I have a spare 99 ZX9R Kinkos/Muzzy AMA motor if you want to try. ~160 to the tire.

I think the newer 9 motor would go in better than the zx10r motor. But you still might need to modify the inside of the frame spar, becuase it's pretty wide.

I think the newer 9 motor with a nice set of flats and a dyna would be a cooler engine to have in a zx7r than a zx10r engine anyways. Plus those late model 9 engines are everywhere.

If we had the upper dimensions of the newer (98-03) zx-9r motor, it would help a lot, that is, a measurement across the top of the valve cover, to see if it will slide between the frame of the zx7r.

I'd also like to know the difference in weight between the zx7r and pre '98 zx9 motors. If I remember correctly, others who have done the switch have commented on the weight difference, saying that it was noticeable. If that is the case, I would be more inclined to go with the wiseco 770 kit in a P motor.

I guess I assumed the zx9r engine would be narrower by a bit because the zx10r has a 76mm bore, while the zx9r is 75mm. I don't know bore spacing. But i know the late model carbs fit between the spars just fine. so that tells us something.

I think that any newer kawasaki motor would need the RH spar modified to clear the timing side. I thought I remembered people saying it wouldn't fit as is in the past. Unless that was just an assumtion that somebody started and everyone believed.
