[QUOTE="greg brillus, post: 178233, member: 597"] The stock Vincent pump works fine for most all engine set ups.......careful engine assembly with attention to the amount of crush on the ET 183 seals is very important......and parts that are made from the right material.......cams and followers are the big ones as they carry the highest load of any engine component, and oil drain grooves ground into the big end liners at the 9 and 3 o'clock positions to allow spent oil to drain easy and fresh oil to enter the big end.......Only the lunatics like me who like to push the engines a bit harder tend to run full pressure oil pumps or similar........I've actually set up my racing single to a 2 start pump, done away with the auxiliary full pressure pump........there are several reasons for this, but running a roller cam and followers you actually don't need as much oil delivery as you might think.......the roller cam has less drag than a flat tappet set up even though the valve springs are running much higher seat pressures than stock at around 140 lb's seat.......this with very light valve train parts used including our 6 mm stem titanium valves, 5/16" hollow chromoly push rods which are about 20 mm shorter than stock and again much lighter........I think our roller followers are only about 10 grams heavier than the radiused followers that Terry supplied with his Mk 5 cams.
