2001 zl600 efi esr with 600 miles....servomotor assy fails causing limp home mode in the cpu, a bog like you read about and 7 mpg to boot....servo problem unknown at this point...buy new unit from cat...almost 300 bucks !! replace it now alls fine in snow land back to 14 mpg...blow the old servomotor assy apart to check it out...motor works fine when 12 volts is applied to it but testing the internal potentiometer ( speed pot to some variable resistor to others ) i find an open in the windings...so knowing i cant buy this part from cat i go hunting to find this part...specs says it should be good for at least 2 million cycles ( made by tocos of japan ) e mail them for help...they tell me this is a special oem part installed in the servomotor assy built by kokusan ( also of japan )..i e mail kokusan directly and fail to get any response whatsoever ( unusual for a japanese company when you go after a quality of the product issue with them ...i work for fujifilm i know ) any way to make a long story shorter than i could be..if anyone knows how i can get this 5 dollar part to renew a 300 dollar assy id greatly appreciate it...oh and for what its worth when your cpu flashes a 6 trouble code its the servomotor...steve

you remove the 4 screws holding down the cpu and there is an led under there that will flash a code if you have a problem...if alls fine with all the sensors it will only flash once when you start it...let us know what you find...steve
