Radiator Fans
Anybody know if the 02-03 Fan system will fit on a 2k 12? Got stuck in traffic again, in the heat. Normally, I would have shut her down, but since she won't start when hot, I had to keep her running. It soon became obvious that the single fan system isn't enough because the temperature kept climbing. Fortunately, I made the light before melt down. I'm also working on the starting problem. I have ordered new starter brushes and plan to have the starter rebuilt, and will install heavier ground and starter wires. I'll let everyone know if this helps. Also, Does anyone know if there is a bigger, heavier duty battery that will work?
Thanks

Mega...Im not 100% sure...but yeah I think it would fit.
Or you could do what the Busa guys do and go to a junk yard and find a fan from an early 90s bike and install it beside the main fan with a manual switch.
How much antifreeze are you running?

No, B1-2 has 2 fans, A1-2 has one. You might take the opportunity to swap to one of our aluminum blades (move more air). Check your coolant level and make sure you don't have any trapped air.

I have the FBG battery on my 12, works well. Got it from Schnitz racing, about $120. Kind of a bitch to get it to fit in stock battery box, have to move the starter relay connection to the very end of box(drill out stock rivets, redrill the holes,etc.) but it will fit! Stock battery will not work well on a stroked or bored 12 once the temp gauge hits about 10 o'clock!

MB,
FastByGast makes a gel cell which can be shoe-horned into the stock battery spot with a bit of Dremel-ing.
Also, MadMike (races for Interstate Battery) has a good suggestion, although the model name escapes me right now.
I would also be interested in whether the newer ZX12r 2 fan set up fits, or could be made to fit a Y2K.

I do have the aluminum fan, but am considering replacing the rad fluid with 2/3 distilled water & 1/3 antifreeze? And actually, under normal conditions the engine temp isn't a problem, not much different from stock. It's just that when the temp gauge gets in the 10 o'clock area, it won't start w/o a 1/2 hour cool down.

I was in the process of putting the 02 setup on my 00. The biggest hurdle is the single dogbone engine mount. In 02 they cast an ear under the frame behind the steering head for the upper mount. That would not be too bad to rig because you could use spacers between the 00 dual mounts and 1 long bolt through the whole shebang. The head bracket from the 02 won't work on the 00 because the holes cast in the head are spaced differently so you would have to fabricate a bracket from scratch.
OK THEN, The 02 setup uses a relay taking power from the battery and then splitting the paower to the fans. The 00 doesn't use a relay and the original wiring would MAYBE BORDERLINE support the amps to run 2 fans. I'm not comfortable with that so I would have to change to the 02 setup there as well.
So after acquiring parts and such I finally decided to do something different. I made some heat shields from aluminum flashing and attached them to the headers behind the radiator to stop the radiant heat a bit. They are similiar to the heat shields you see in Dennis Kirk that are chrome to keep your legs cooler on cruisers. This alone made a big difference when idling in traffic. Not that mine ever overheated, I'm just anal about watching the guage creep. The one thing I'm not fond of is wrapping the pipes, but that is a great way to keep things cooler.

ZX1012R great report. I looked at the same things. Wrapping my headers lost power. I spaced my radiator out 3 -12mm nuts forward. (Had to trim the center fairing about 1/4 inch to fit and that helped some. I do not know the Water antifreeze mixture, because I set it by the coldest temp I can imagine on average in DC. 10 degrees above zero. which I think is about 20 to 25% antifreeze. What I did was mix the water with Water wetter and then add antifreeze until it floats at 10 above zero and use that mix (Distilled water). I also have an aluminum fan.
I liked the idea of the heat shields on the header best. I will look into that next!

I recently had a little deer incident which will facilitate some tear down and new replacement stuff. I will try to get some pictures of the shields when I have it apart.
I also run a 25% anti freeze 75% distilled water mix and add the recommended amount of water wetter. And I spaced the radiator too with a little trim of the lower cowl. A couple of weeks ago I got caught on the Merritt Pkwy here in CT in about 95 degree weather in traffic and the guage never went past 10:00 o'clock. The fan runs constantly and will never cool the radiator enough to turn it back off until you get moving but I was happy to see the guage stay there for about a half hour.

Yjen you are at 100% of what is necessary! During bike week on main street last year and on the beach, I saw the guage blinking and all of the marks lit up!
I looked into some larger AC Fans with better blades and just quit for a while!~

Koz, thx for the tip!
I have been using Water Wetter which seems to work somewhat, but hell, for $26, I'll try Jeg's stuff.

The Muzzys fan, a bleed of the thermostat, Water Wetter, & bingo! Mine runs much cooler now & the fan seems to run much less duration when it actually runs...
'Course mostly mild climate here helps...splitting lanes...etc...

The cure to the 1984 to 1986 was a lot easier to cure. Remove the shrod on the back of the fan for air flow, remove the plastic that blocked air flow past the exhaust and the #1 solution was the replace the Oil temp sensor with a coolant temp sensor. Turned the fan on at 210 oil tem as opposed to 230 (or was it 260 degrees) oil temp. The ZX12 has almost none of this! Matter of fact the Oil cooler is more of an oil warmer for faster warm up!

1. Use the least anti-freeze as possible (the more anti-freeze, the less heat transfer). If the lowest temp. in your area is say +10 degrees, mix (use a hydrometer) the distilled water/water wetter and anti-freeze for an extra 10 degrees. (0 degrees) Make sure you bleed the system of all air! Keep the radiator clean and clear of bugs and debris.
2. Install a by-pass switch, in parallel, with the temp. sensor. I used a simple illuminated automotive switch, so that it lights when the fan is on. It will also go on automatically. As soon as you see traffic turn it on.
Between the right mix, water wetter, and the switch, I've been able to operate in 100-degree temps. with no problem.

Heat Shield
Been thinking about fabricating a stainless steel heat shield to mount between the pipes & the rad. I know this
has been done before, I just wish I could find a picture so I could decide on the best design. I could use individual heat shields on each pipe, but don't know if this would be the best solution ?

After looking at this, maybe putting 2 hose clamps (Top & Bottom) then the Stainless Heat sheild and 2 more hose clamps (Top & Bottom) would work! The 2 inside would allow the air space so the heat would be blocked!
I remember using white heat resistant paint on some pipes one thim and they really ran cooler than they did when they were black. Maybe it is time to experiment again!?

I wish I had my bike here to take pictures of the heat shields. It's really easy to make. I made one for each header about 8" long to shield the radiator and the hose under the radiator. I took aluminum flashing and cut them into ovals and then shaped them around the handle of my floor jack. Then I made a "coffee mug handle" type of bracket for each out of the same flashing. I riveted one bracket to each shield and then attached them to each header with one hose clamp each. K.I.S.S. is my motto here. The left most shield I made larger to shield both the radiator and the lower rad hose. I promise when I get the bike back from the estimate I'll take pictures. Or I'll start making a bunch and retire from the profits? I don't think so!
This is what gave me the idea. http://www.denniskirk.com/powervendor/details/detail.asp?serverid=nlStreet&PartNo=442699

Dave, good question about the Oil cooler because what Kawasaki has is really an oil heater that also cools! I think they did it to meet emissions with a faster warm up! You posted your thread just as I was thinking about the exact same thing!
