I have a Norton
P11 motor in a Trackmaster frame designed for a Triumph triple. I am curious about the oil return pipe in the frame, if it is up to the job of evacuating the crankcase. It has a fairly small exit hole which seems to flow at its maximum at all times. On a stock bike usually the return flow settles down after all the wet sumped oil has been pumped out and it begins spitting a mix of oil and air. Not this.
If I knew the output of a triple motor's oil pump and the Norton
six start oil pump, I could compare those figures. However, the oil return hole looks skimpy in either case. The big question is if the Trackmaster oil return was fully up to the job. The spigot in the frame is large enough but at the top, the exit hole is quite a bit smaller. Has anyone had a lot of experience with Trackmaster frames and did this ever give problems such as the motor swamping itself?
