Accusump to fix cold start oil system deficiencies

[Q777]

I have read in a few places lately about the fact that it takes up to 90 seconds for all oil galleries to receive a sufficient oil supply throughout the Testastretta motor.

Has anyone used an Accusump pro-oiler to pre-pressurize the oil galleries prior to starting their motor?

Amsoil has a smaller unit again, at under 8" long and 2.5" diameter.  I'm sure that there are even smaller ones around.  http://www.smartsynthetics.com/products/amsoil-prechargers-amk01-amk02.htm

I have the larger unit on a pretty highly stressed 900+hp supercharged small block, and it's pretty comforting to see the oil pressure gauge showing over 50psi before I've even hit the ignition.  There are other benefits for maintaining oil pressure during severe braking and cornering, but that's seemingly not an issue for the Ducati motors.

So, with most online performance stores charging about $130 for the Accusump, the only downside would seem to be the little bit of extra weight to carry around on the bike.  All the better reason to add a bit more carbon fiber to offset the extra weight 

I'd love to hear if others have considered this option to ensure minimum wear and tear on the motor...

I'd think if it were that important, bikes/cars would already come with them. With some Ducs out there having 60k + miles on original engines, it would seem that adding 'pre-oilers' is overthinking a non-existant problem and as long as you change the oil hot and often the engine will last. Just maintain the bike and you will be fine.

I'd like to see oil pressure before start up too, but not going that far.

Even when in a hurry, I do always let the bike idle a couple of min. before taking off.

When I have time, let the bike show water temp going up and in the mornings I'll let it hit up to 150F before pulling off.

I think a pre-oiler might make a Duc engine last a little longer, but since short engine life isn't an issue to begin with it seems like trying to solve a problem that doesn't exist.

Just adding a complication to a motorcycle that should by definition be simple and functional.  Not for me.   Now, adding an oil cooler to a Monster that came without one and is running in a hot climate might be a different story.

  I find it very hard to believe that it take a minute and a half for oil to get to all th right place after start up. That just doesn't sound right.

+1. Maybe in Alaska in January running straight grade SAE 60. I'm curious to see if there is any real science behind the 90 second claim.

That was exactly the case on Honda CB-450s...

That was a long time ago though.

I remember reading elsewhere on this forum that someone had popped the valve covers on their bike and it was more like 5 seconds max than 90.  I think the 90 seconds is a scare tactic from oil companies.

You have a point in that the CB-450's had a roller bearing crank which does not build much oil pressure.

I'd like to use one on newly build motors and motors that have sat for a long time, but there should be enough oil hanging everywhere to make it kinda silly for everyday use.
How/where would you attach it on a Duc?

The story I always heard was it took a while (I also heard ~90 seconds) for oil to pump to the vertical head on the desmoquattro motor (no idea about the testastretta), due to the valves in the oil lines being one-way, so oil could drain back.

No idea if it's true, but I'll certainly let my bike warm up for a few minutes before I jump on it.
