2001 Twin Cam B. Had a collapsed lifter. After a lifter replacement the oil pressure gauge is not acting the same as before. Use to top out at 60psi or so when it was cold no matter how much rpm. I'm assuming it bypasses some how. Idled at 25 when warm. 52 when riding and warm. Now when it's cold, when you blip the throttle, it will swing to 70 or so. Doesn't do it all the time. When it's warm, idle pressure is lower than before. Riding pressure is around 40 or so. Bike has a new set of Wood Alpha Series lifters and existing gear-driven cams. Adjusted 4 turns with 32tpi pushrods. Ran a couple of hundred miles, readjusted. Fueling cam support and oil pump. Thanks up front.
