"Thinking about changing back to hydraulics. What would be your suggestion?"Seriously? There's a lot of pretenders out there. I used to use Jim's stuff until I went from gaskets to actual working parts and they took a shit on one of my builds. Almost cost me a customer.
I suggest you mic the lifter bodies to see what kind of clearances you have - then take a 0-1" mic with you to the dealership and mic the Evo lifters they have in stock and pick 4 you like. Yeah, I know, they'll have some pimply-faced little prick at the parts counter you'll have to deal with on this...but you'll get over it once your ride is up and running. Adjust the new hydraulics according to the book (dry).
In my opinion...solids are for the dragstrip and cam profiles over 260 degrees total duration. Maybe one in 100,000 Harleys on the street can float a hydraulic lifter. I mean, who the fuck winds there motor past seven grand?!
"Also, what actual oil pressure should be seen after warmup and what pressures are the "idiot light" sensors usually set for?"
Maybe you didn't understand my explanation of what designates the oil pressure reading at the gauge. All things in good working order, the wear on your engine will designate the oil pressure at the gauge. That Evo's use a multigrade oil-viscosity also fucks with that formula. I can't give you a number concerning the gauge reading...and no one knows what the factory idiot-light sensor is set for. I'd assume zero backpressure. Idiot light are usually either an on or off situation.
That help?
