I had nothing better to do today so I took my bike for a dyno run. I’ve never done this before as I always thought it was kinda pointless. With the H2 on the horizon ( see what I did there, its on a ship that’s out to sea on the horizon ) I wanted a reference point to measure power against. This bike will be rebuilt when its raining and I can’t ride my Weapon of Massive Fastness (H2) and I am putting it on a serious diet as well as opening fully out the inlet rubbers, and full service.


It’s a 15 year old zx12r A1 ( project 320 ) with 26K miles on the clock.

For those who don’t know the project 320 stood for 320 Kilometres Per Hour. In the U.K. and U.S.A. this means 200 Miles Per Hour.

It is supposed to have made 178 bhp and 186bhp with ram air, when new.

I know the air filter (K&N) has covered over 5k miles and I don't know when the plugs were last changed but certainly not in the last 5k miles. It runs a pcv (which isn’t mapped to this bike but came off a bike with the same spec ) It didn‘t go more than 0.4% out of the optimal Air / Fuel Ratio. It has a full titanium ackrapovic zorst..

It made 172 rear wheel bhp. Allowing a low figure of 10% for "drag" this is about 189 at the crank. Add to this the ram air effect which gives an extra 8 ponies.

All in this bike stands me at about £2,600 ($4030). The H2 is £22,000 ($34,100) hence ten extra horsepower for £19,400 equals £1,940($3,007) per pony.

Whats most weird is I feel more love for my H2 now than I did this morning!:D

I love my 12. It's a 2001 and still holds its own today against almost anything including my S1000RR. Do you have a copy of the "Silver Book"? Great read produced by Kawasaki on how they built the bike.

Rock.

The "silver book" is one of life's pleasures I have yet to enjoy. I got it cheap because it had been down on the generator cover. It had been badly repaired and the fly wheel hadn't been correctly torqued causing it to come off and short out the windings! I got off my dealer the genuine factory tools to repair it correctly. Very kind of him at the time, you don't forget these things when you come to order a H2.

Any info on where the "trick" inlet rubbers can be had would be appreciated. As would recommendations on a slipper clutch for it as it is "grounchy" on launch.

Heres a link to the Silver Book:

The Kawasaki ZZ-R 1100 / ZX-11 / ZX-12R Ninja Repository

The good stacks were called Bear Stcks I believe, from down under. Muzzy still shows theirs last time I checked.

I dont think the "slipper" is to blame for the grouchiness. I have heard stronger spriings help, but you get a stiffer lever pull:eek:

On mine, different oils helped with the noise. Currently using Motul semi-synthetic and the beast only complains occationally...

Sorry i was unclear,,, the clutch is standard at the moment , and tired. I am looking to replace with an upgrade thrown in for good measure.
I loved the silver book, those concept sketches really showed the way forward. Lots of the styling got used later on the 14. Amazing that it is now 15 years old. Any ideas where to purchase one please?

I note the dry weight is 213kg. Does anyone know the wet weight please? I reckon coolant 2 kg , oil 4 kg, fuel 19kg. Because I guessed fuel at 19 kg its the same as a H2 ! 238 kg.

Look out for a zx12r with a H2 style seat.

Used to see them on Ebay once in a while...not sure lately.

You're pretty close on curb weight, service manual shows 243kg.

Post some photos mate when you've set it all up with the seat etc.

"Grouchy" is a good way to describe the launch at times. :) But when she is rolling .... OMG!

ah yes I remember that, great product.
I'm aware of Muzzy's work and highly respectful of their great name particularly in drag racing clutches. I want to circuit race mine ( zx12r in the wet ) H2 for dry days so I am looking for a slipper clutch. Spent 20 mins with some scales yesterday and found stock exhaust weighs 10.3 kg!!! headlight 3.3 kg seat 3 kg etc.....
