(None come to mind, >though.) I spent too long restoring this and falling in love to get anything else:) And there's nothing else in the cop world that can stay with a KZP. And my God, they're just *gorgeous* and while a cager will look right thru a HD or a BMW to see the car on the other side, that particular fairing gets the attention of lots of driver's wallet-protection reflex and that's a leg-up in the visibility department nothing else can give me.

It just doesn't matter what great strides European diesel manufacturers make, if the products aren't cost competitive in the US. Americans will probably be buying Chinese or Korean built diesels in the future, because that's where the cheap labor is located. I doubt that I will be seeing any Jaguar diesels around here. And, in a blurb crawling across the bottom of my TV screen (as I watched the unfolding drama of the demise of the fat gold digger who inherited half a billion U$D), I noticed that the EPA wants diesel particulate emissions reduced by 90% by 2015. But I didn't make any effort to investigate the story any further. Like Gene Wilder said... (1) "It just doesn't matter", ad infinitum.

I should see what is possible. If you decide to go with the big fan idea, be sure to keep a close eye on the plastic connectors that hook the alternator and regulator to the motorcycle wiring harness. Extra electrical load melts those cheap plastic connectors. > My interest was possibly mounting a cooler with a thermostatically operated > fan, like you find on trials bikes for the coolant. You could probably find some sort of thermoswitch that closes when the oil temperature gets up around 300 degrees F, and it will get that hot in the summertime. Just plumb the switch into the main oil gallery. If you go to www.partsfish.com and look at the CRANKCASE diagram, part number 92066 is the main oil gallery plug. You can see that the oil pressure switch is right beside the oil gallery plug, and that's why it was so stupid to return oil from an aftermarket cooler to that point. > Do you have any ideas as to where they ended up on the police bikes?

Dan Gurney modified a lot of KZ1000's for police use in the 1970's, but I never paid much attention too them when they had me pulled over for speeding. I looked at the 2003 KZ1000P diagrams on www.partsfish.com and I don't see any oil cooler on any diagram. The KZ1000P still uses the old style roller crankshaft that requires only a few pounds of oil pressure and still has cam bearings in the cylinder head. > If this works the way the heating loop in my den works when the check valve > craps out, the warm oil rises toward the cooler... so in that direction.

Personally, I wouldn't want to disable the crankcase breather, but racers wouldn't much care what systems they defeated when they modified an engine. There is probably a baffle plate inside the 14070 body, breather that is shown on the BREATHER COVER OIL PAN diagram. It would be easy enough to take the one bolt out of the breather body to see what you've got there. You could also drill a 1/4 or 5/16 inch hole in the camshaft cover and return the cooled oil to the area of the cam chain tunnel so it could easily flow back down to the crankcase. You really don't need large diameter hoses (like 3/4ths or 1-inch) for your oil cooler, unless you're counting on the extra cooling effect you get from the hoses. It might look silly to some unenlightened bystanders, but all you would need is small diameter hoses to an oil cooler, since the flow through the cooler has to be restricted in order to avoid robbing the cam bearings of pressure.

One other point that I neglected to mention is that lean fuel/air mixture madated by the EPA to reduce air pollution and allow imported motorcycles to pass emissions tests cause the engines to run hot. Opening the idle mixture screws 1/8th or 1/4th of a turn really helps keep an engine cool in traffic on hot summer days. It's a simple matter to drill a pilot hole in the EPA anti-tamper plugs that conceal the idle mixture screws. Then you screw a small sheet metal screw into the pilot hole and pull the plug out with a pair of pliers. Then you can open the idle mixture screws about 1/4 of a turn counterclockwise and the engine will run cooler, start easier, warm up faster, and have better throttle response. You can tell if you have turned the idle mixture screws too far CCW, the idle RPM will slow down. The mistake that amateur mechanics make when they adjust the idle mixture screws is they think the idle RPM should keep increasing as they open the screws. When the idle mixture gets too rich, the idle speed slows down and they compensate by turning the master idle knob clockwise. Then the engine idles far too fast when it gets warm and that drives the amateur mechanics up the wall, since they don't know that the extra gasoline that makes the engine idle too fast is coming from three transition ports uncovered too soon by the bottom edge of the throttle butterflies. The corrective action for high speed idling is to turn the idle mixture screws clockwise a bit, and then readjust the master idle knob.
