Is that the new pump from (hope I remember this right) TMan? Have only heard the name and the vaguest of details. How's it better?
(no, don't have an oil pump in the pile of Road King parts yet)
T-Man is one source. A dude name Thayer is the guy who came up with it. This is from T-Man's web site.
This pump is designed to scavage the flywheel and cam areas individually, which results in a mark improvement in oil scavaging and control of vacuum within the engine. This allows the engine to run freer at extended high RPMs for extended times.
Precision machined to provide consistent oil pressure and improve oil flow, resulting in maximum oil system performance. This pump has been dyno tested at T-Man Performance with results demonstrating it's superior scavaging performance. Field proven at Bonneville Salt Flats when achieving World Records in the 1650 cc class.
*Due to the high precision tolerances this pump is manufactured to, no more than .0035" pinion runout should be allowed. Greater runout than .0035" may cause damage to the pump, which is not covered under warranty. It is strongly recommended that the engine's crank assembly be trued and welded to prevent excessive pinion runout.
"Of all the pumps I have tested over the years, this pump offers superior performance results. I am so pleased with the performance of this pump, that I strongly recommend it for all engine builds and oil pump upgrades." TR Reiser"
hd-dude said it works very well. Since I've had an oil issue with this scooter twice, I'm trying this 3 stage pump.
