"Curiouser and Curiouser" said Alice to the Cat.

We are challenged in that we MUST maintain flow and pressure to the head cam journal bearings -- and we dare not violate these precepts or we can join the many who are in search of the rare spare head with virgin undamaged head journal bearings.

Pressure -- don't tap any flow unless pressure is up to 9-10 psi so you have some oil volume to steal from   (the designed crack pressure inherent to the check valve does this)

Flow -- use only a small 10 psi flow through a 3/32 drilled orifice passage to balance the alternate flow amount.


Conclusion:  the amount of bypass oil going through a 3/32 drilled orifice and on up through a massive 1/8" tubing to the bypass filter is sooooo tiny it has to fall under the heading of "why bother?"  

Stealing bypass oil from the oil pump simply isn't worth the risk -- there is not enough flow and pressure there to steal from safely.

=================

There is no excess pressure or volume being vented in the Savage oil system by any form of bypass valve.   It is all going to the head or the transmission.  

This scarce resource is intentionally metered by Suzuki engineers using a form of tuned pilot jet technology to send all extra pressure and volume to the head.

=================

Folks running them cute little oil coolers off the oil gallery on a Savage are living in a world of increased risk.   Our bikes can kill the cam journal bearings naturally without bleeding off the existing oil pressure and volume to go run an oil cooler.

Running temperature and pressure gages is fine -- no oil really moves around when you run a pressure gage.

some interesting stuff

There are hydraulic losses any time a fluid is pumped thru anything.Every turn & every inch of plumbing requires power to drive the fluid. If a guy took a piece of 1/2 ID PVC pipe & hooked it to a pump that runs @ 2 GPM & the pipe was dead level & 1 mile long, how long till the water comes out the end? It never makes it, because the pipe ruptures, providing our theoretical pump pushes 2 GPM, regardless of the pressure it encounters.

Well, I enjoyed playing with it, building up the filter that is.  Playing with understanding the system was fun too.  




I borrowed a large face 0-60 psi gage from work so I could do a temporary rig up to monitor my own bike's pressure levels.

I <may> hook up the remote tank rigging using 1/8" tubing all the way back to the head then hook up the gage below and monitor the pressure as reduced by the entire system.  With all the tubing and filter resistance it should be greatly reduced compared to measuring it at the engine tap points.

Why measure it at the end where it is greatly reduced?  One, it is totally real to the attached filter system pieces.   Second, it is cooled down by all the tiny 1/8" copper tubing just about to air ambient temperature.  

Third, because pressure is reduced and temperature is low, I can splice in a tiny, easy to trip (fine increment adjustment) plastic check valve to clip a tiny amount of oil volume at an exactly known pressure so I won't feel like I am going to kill my engine.

Measuring that 1/8" check valve passed volume with a cup measure, I can precisely state the volume stolen from the oil system and how long it would take to cycle my oil sump through the filter one time.

Ah, gentle reader .....

This discussion went off line for a while until Versagen discovered the relatively inexpensive ($25) fuel oil filter systems with the fairly cheap ($3) replacement filter elements.   The discussion then hotted back up and got down and dirty practical as two experimental systems began to take form ....

I look at it lustfully -- like I said, if I hadn't already started on the path I am already partially down I would definitely be using your system.  It is a superior starting point in every aspect.

Go there, gentle reader follow Verslagen on the choice of filters -- do not go where I went as if I had it to do over again I'd get Verslagen's fiter as my starting point too.


============


Same token -- both Verslagen and i have to beat the same vibration and heat problems running the plumbing.   Gander at the differences in thoughts and methods accordingly.  He will swing minimal, smaller and close up, I will go longer further and bigger.  

We both get there, but the differences are interesting ....


(especially when you hit the edge of a ditch up in the mountains on that there infamous mountain trip)

One of these QD fittings might work nicely with your idea I think so you could literally 'plug' the pump into bike.

Harbor Frieght sell an air brush hose with a miniture quick connect for less than $10 each.  I doubt those are valved, so would need to be capped when not in use.
