Can I use ultra duty EP to lube up cam befor reassembly?

   If you replace the cam and the motor is together, you could jack the rear of the bike and add your 2.5 Qts of oil through the intake valve cover flooding the "bathtub" under the cam lobes . The rest of the oil would return to the oil sump. With the bike still jacked you could place the bike in gear and manually rotate the rear wheel ,that should force the oil pump to fill the filter and passages up to the cam ,so that when you first start the bike lubrication to the cam should be almost instantaneous.(I would hope )
