Wir erinnern uns
Das was bei HD nach oben streut kommt in die Behördenfahrzeuge.
Damit bezog ich mich allerdings auf die Produktion aus vergangenen Zeiten - welche Streuung beim heutigen Motorenbau noch ist, und wie das dann gehandhabt wird, wäre sicher mal interessant.
Die Praktik mit der Leistungsmessung und dem Abschöpfen der stärkeren Motoren für die Cop-Bikes war Übereinkunft vom Werk mit der Polizei (z.B. waren oder sind auch die Tachos der Police-Bikes exakter
kalibriert) und war zumindest bis ins Evo-Zeitalter praktiziert - so haben es HD-Ingenieure erzählt :
".....in 1985 i toured the engine plant in milwaukee.we watched the engines and transmissions get machined and assembled.
when the assembled engines were ready to be tested on a engine dyno a tech would mount the motor, attach the carb, exhaust and oil lines and start it up.
it would run for a while then he would start getting on the fuel.he ran it hard and he would document the HP for each motor.
the tour guide told us they needed a specific HP range.
anything below the range was pulled out and redone, anything that had exceptional HP was pulled and used on cop bikes.
anything within the range was used on regular production bikes. i ask him why there was different HP from one engine to the next.
he said it was just the luck of the draw. all parts were manufactured to the same specs but all the parts were not exactly the same.
in assembly some parts just worked better together then some other parts and would make better HP.
the tour guide was a retired engineer with many years working for HD. ... "
