it would be prudent to have an anti drainback check ball valve in the outgoing oil line

How does that work? Doesn't the pressure from the pump ensure the flow is only one way?

the extra plumbing and oil cooler takes a certain volume/time  to fill, if it has to be filled every time the engine is fired well thats not optimal
a checkball valve can eliminate the situastion,nip it in the bud it doesnt even need spring loading if mounted so gravity helps its fuction ,something like this cheap insurance

Awesome. I get it now. Thanks for the explanation.

A very important consideration on the 360, which can take almost a minute to get oil from the sump to the head.

A small external pump could be fired up w the key, to get oil moving even before bike is running.

This isn't a system to replace the existing circuit, it's just an added path. No cooler, but a reservoir to increase capacity by a quart.  The reservoir will act like a regulator. It will stay full, and flow once pressure is reintroduced. I didn't turn it into a dry sump.

I would just run a small diameter line direct to head/cam bearings.
 Fitting a cooler, you must have an anti-drainback as pointed out

an accumulator then ? maybe not but accumulators are sometimes used in road race vehicles

An accumulator isn't flow through.  It's a reserve that allows you to add oil into the system, usually by compressed air.

yep they can save an engine in a situation where the pump starts gulping air
and can be used for prelube prestartup
is what you are doing a proven ? i am not grasping the concept

It's been done many times.  Just another way to compensate for the machine's notorious oiling issues.  I've done PJ's internal mods on a stock machine, and this motor has had the stock galleys opened up.  I'm just taking it another step further with the bigger bore and eventual cam upgrade.  I will likely add the cooler at some point, and include a check valve if that happens.   I may end up adding in a pump, too.  First, I want to see where this takes it.  Here's a version of the mod with a pump:



 It should keep the motor temps lower, external cooler or not.
