opinion on ZX7R with 95 ZX9R engine

Would like your opinions on a 2000 ZX7R with a 95 ZX9R engine installed.
The motor was supposed to have 10,000 miles and is stock except for a pipe and dyno tune.
It dynoed at 129.xx horsepower.
Any experience with this combo?
Still thinking and looking for a nice bike.
Thanks

I'm sure it can be done.... but I would say that it is only worth whatever NADA says that year 7R is. The problem is that you don't know if the install was a HACK job or not.

I have seen a GSXR 600 with a GSXR 750 motor in it.... but not that combo. That power is about where it should be for the 9R motor of that year!

If you want details on this modification, check out kawiforums.com and redmonkey.com/7R for details. It's a popular mod amongst 7R owners.

Well the Muzzy race special ZX7 Raptor was a awesome bike and I believe they were a 750 punched out to 855 cc? Maybe it was 864 I don't recall. The ZX9 motor is bullet proof and has plenty of tuning potential so I think stuffing it into a Zx7 frame would give you a cheap version of say, and R1.

But for the time and labor involved it might be easier to find and buy a used R1. Or perhaps sending the 750 engine to Muzzy to superbike prep it?

I have read many threads on the topic on both sites I mentioned and that seems to be the most suggested mod when anyone ask's how can they get more horse power out of their bikes.

Everyone needs more Hp right? Unless you drag race or road race (and with this mod it would be illegal in most superstock or superbike classes) you don't really need that much more power. And if you did happen to track day or roadrace spend the money on suspension upgrades and riding lessons before you need more power.

The ZX7 if I remember correctly puts about 115 hp to the rear wheel. The ZX9 was up to about 127. You shoudl be able to pipe, jet kit, air filter, overbore, head/ piston work into the same range...if not more. All for cheaper unless you just happen to have a wrecked 9 layin' about.

I did some checking into this because of a bike for sale with this already done.
It seems to be a pretty straight forward project and not that costly.
You buy the kit from BMR Racing for like $450 and then a used ZX9R engine from a 95-97 bike and it bolts in using the ZX7R exhaust.
Dont know that I would go through the trouble but dont seem that bad to do.

The insurance wouldn't be that much cheaper. Personally, I'd rather just buy a bigger bike. Also, wouldn't you only be covered for say a 7R. Otherwise, you'd have to inform the insurance company of the bigger engine if you expected enough coverage to cover any losses (ie. stolen bike).

at minimum it would be a good sleeper.... and it would be cheaper hten owing another 6-7K$ for a new bike.. save ya a couple grand.

i keep debating sedning my Z1000 motor to muzzys to be a 170HP bike or to sell it and owe 10K$ after selling the Z and paying it off to own a Zx-10R... Muzzys would cost 2K$... 8K$ saved....equal horsepower

owe 4 on the bike nad could only sell for 6K so why give up a bike with low miles(13K) to owe 10G's i could put on my house instead

That's what I'm getting at Scott. The money side just don't make sense.
