I may have asked wrong. But, what I mean is where does it fall in the system.
The oil pressure sending unit on the Cone-Style Shovel and Evo is on the oil pump. I believe (and I very well could be wrong) it "measures" the pressure coming out of the pump, before it goes to the rest of engine.
Does the Twinkie measure it in the same place in the flow of the oil?

Is the oil pressure sending unit in a different spot in the overall oil flow on one of them than it is on an Evo or cone-style Shovel?
Just curious. Yup...Not sure about the sending unit...

Just curious. I'm not sure where its located on the Evo's Dave... On the twinkies it screws into the front of the engine block down low just behind the front header pipe. About 3" long w/ plug in from the electric oil guage on the end of it.

How much oil pressure did you really have before you swapped that spring? With a bad sending unit, you may have had plenty and didn't know it.
But, if it quieted things down, cool... Good point Dave, my sending unit was weak so it turns out. In retro-spect I should of replaced it first. Before I did anything, running down the road I was carrying between 25 to 28 psi hot. Idling hot maybe 5 psi at best. With spring change boosted it to 40 hot psi 10 idle hot. WIth new oil sender now its up there 50 psi hot running at speed 20 psi at hot idle. Motor sounds very smooth and quiet. No leaks! Total cost approx $50.00 Idling I am just below 5 psi and on the road 32 psi...

Shows more oil pressure now, but doesn't maintain as high pressure readings as my 2 other buds that did the same spring change out.... But I must say the motor is quieter practicly no valve train noise at all now. Went ahead today and replaced the oil sending unit. Was $33. at the dealer holds a min. oil pressure of 20 psi now when the motors hot. 50 psi cold.

Ok yeah within the oil pump itself. This deal here is seperate from the oil pump. It works in unison with the oil pump but this particular spring is outside of the pump- is in the cam plate.

Sounds pretty basic, I wonder what exactly the spring is pushing backpressure against.... The shafts you pointed out are actually, (round one) where the old chain tensioner was mounted and (square one ...really hex) is a tapered oil pump alignment tool. There is a valve in there I believe that is controlled by this Spring or vise versa....

Curious, do you remember enough about it to point out where on this cam plate the spring would go?

Thanks Empty, yeah I drained the oil, yanked off the exhaust and took off the cam cover yesturday evening. Ben came over took him all of about 2 min. to take out the little roll pin and replace the stock spring with the baisley spring. He said his motor is quieter and he believes that the increased oil pressure is a good thing as opposed to sitting at a red lite when its 100 degrees with 0 oil pressure. LOL!
He's coming over here in a few min- with a torque wrench- to tighten the cam cover screws to specs.....

After reading the guy's directions on 'how to' there Jeff, let me throw a small piece of advice that I can see this guy is definately not aware of.
1. Make sure you have the manual on your bike.
2. Yes there are bolts with Loctite on them, make sure you chean them and the holes well and use the correct Loctite according to your manual.
I can see you are determined to have this extra oil pressure, so make sure when you do it you don't take any hack shortcuts and keep it clean.

Ok this is the Spring.. Got this info off another Board. Its called the Baisley Spring. Installed Baisley spring-BIG DIFFERENCE!!!!!!
I just installed the Baisley oil relief valve spring in my 04 Road King Classic and can't believe the difference it made in valve train noise. The on again, off again "ticking" while cruising is now gone.
Baisley Hi-Performance
5511 N. Interstate Ave.
Portland Oregon 97217
(503)289-1251
Part number is LMR-002
for 1999 and later Twin Cam A and B motors
As quoted from instruction sheet:
*Increases oil pressure-15%, typicly 5lbs
*Quiet running motor
*More progressive spring rise
*Use in any TC A or B motor, even stock
*A Must Have for cams requiring higher valve spring pressure
*Restored oil pressure throughout the oiling system when using high volume piston cooling jets and high performance and race tolerances
*Squared and ground ends for less variance in installed length and pressure
*Designed, engineered and manufactured to our (Baisely's) specs for this application-not a "hardware store" spring
A version for Evo is available too.

I used to worry about pressure, then I remembered my old '53 Chevy wagon with the babbet bearing 216 ci 6cyl. That engine had an oil pump all right but it just put pressure on the valve train. The mains got only splash and the rods had little scoops that picked up oil from a trough that was filled by the pump.
Now that old car made several trips across the country, even the rockies!

Randy, I understand more about how the motor oils itself now too after MT and Dave and others enlightened me today as well... high oil pressure isn't much of a concern in a roller bearing motor I now understand. You all are great to share ideas with. well most of the time... LMAO!
