[QUOTE="davidd, post: 178481, member: 1177"] As Greg points out, the delay of oil appearing at the filler neck on start-up is dependent upon the amount of oil in the small scavenge chamber behind the flywheels. So it is beneficial to have enough oil in the sump to allow the flywheels to scoop up some oil and drag it to the scavenge chamber. You can overfill the sump for a few turns of the flywheel and then drain the new oil out of the sump and pour it into the tank. On the Comet racers, I install a new drain plug for the scavenge champer so I can drain all the oil, as well as squirt some oil into the chamber on the first start. [ATTACH type="full"]61799[/ATTACH] The flange drain plug is the new drain. [ATTACH type="full"]61800[/ATTACH] From the inside, the drain on the left is the sump drain and the drain on the right is the new scavenge drain. I did this because I had some problems with removing contaminated oil from the engine. I had some bad oil in the engine and I could not get it out without having to split the cases. This would be unusual on a stock bike, but having done the mod to drain the oil, it was easy to tilt the bike and squirt some fresh oil in the chamber for priming. David [/QUOTE]
