Are there any benefits to having a larger oil cooler? I love the look of the beefier coolers and radiators of the S4's! If there are any benefits does anyone know where can I get one?
Thanks!
Might be a disadvantage. There's no thermostat like with a radiator so oil is always running through the cooler. If it's too big you could potentially run at too cool a temperature. Not likely I suppose but possible.

As a minor threadjack, anyone know if someone still makes thermostatic oil bypasses for the oil cooler?
Once upon a time you could get them, but nobody seems to make them anymore.
Without a fan, any radiator (for oil or coolant) doesn't do you any good when stopped, which is when it's most needed.
Going with a larger oil radiator is only necessary if your engine is running too hot at speed.
It should be noted that running too cool is bad. One study, IIRC, found that water-cooled engines with a 160 degree thermostat had twice as much wear as the same engine with a 195 degree thermostat.
"Cooler" is good when you're talking about intake air, but not necessarily when you're talking about oil.
so a temp driven fan attached to a normal oil cooler would solve all the problems?
Actually that's not entirely true. A larger radiator is going to shed more heat, even standing still, than a smaller one. But not much more, since radiant heat loss is much lower than convective heat loss.
This is one of the reasons I'm looking for a thermostat: My bike is very slow to heat up on my morning commute, but will overheat if I completely bypass the oil cooler.
I was looking to go with one of the S4RS style trapizoid shaped oil cooler. I instead ended up with an S4R oil cooler. The frontal surface area is slightly larger than aircooled monster oil cooler. I also like the look better. My temperatures have dropped a few degrees consitantly over the stock unit. I don't know if the temperature drop is due to the cooler shape or slightly larger size but it is lower none the less.

Aluminum foil over half the cooler? Will warm up faster but still cools some once you're running.

Much as I loves me that polished Aluminum, that's a bit ghetto.
Although, technically it is better than cardboard :)
get a billet screen that has smaller openings for the winter.

Duct tape. ;)

I install an oil cooler on my 620 in the fall and noticed that it's taking forever to get up to temp. Was thinking about making a bracket + screen to snap onto the cooler. I guess foil would be much easier and hassel free. Why didn't I think of that? Thanks for the tip
Yeah, need to do it myself as the bike takes too long to get to temp. I figure some heavy foil and two zip ties are easy and pop right off in the spring. Duct tape leaves goo. :P

Duct tape leaves very little goo at low temps and for short periods of time. It's also pretty easy to get off and I'm pretty lazy.
When I use tape it normally gets removed mid ride.
Yeah, I just look at all those fins and I can't bring myself to duck it. I don't need that thing full of goo AND dead bugs.

You are thinking of the ones from Evoluzione - no longer made - I was just reminded about those recently by a Ducati.ms member who has one (and I asked if it was a Mocal). On to the Mocal:

As far as oil coolers go, I only know of Anthony vending the NCR unit (which is now curved also, and not straight like the stock ones), but if we can find a vendor for Febur, I would like to see the cost on it as well. I want to do Hypermotard style lines as well so the horizontal belt cover is not obstructed. Not only "much cleaner" but also much more user friendly come service time. [thumbsup]
I hate to send people off-site, but these are good examples:

Febur Oil Cooler: http://www.ducati.ms/forums/showthread.php?t=56083 (http://www.ducati.ms/forums/showthread.php?t=56083)
I should also note that I think unless you know you are running hot and live in an environment where its frequent to happen, its not really something to mess with. Too Cold Oil is bad like too hot oil is bad. Cold engines don't run well, the oil will be too thick.
Quick fix for info? Get an oil-fill cap temperature gauge and see.
It seems like additional oil coollers (you can run two of course, one above horizontal cyl, and one below) or a higher-capacity oil cooler would be a good idea, for example, if you played around Las Vegas a lot and got stuck in traffic frequently, or had high compression pistons and other motor work that would produce additional heat.
This is something on my list, but I've also found that changing brand of oil will affect the temp as well. My bike runs noticeably cooler with Mobil 1, compared to Motul. 40 mins commuting in traffic, splitting most of it, I get home at 220-225 on the dash and with Mobil 1 it's 5-10 degrees cooler.

I looked at those before, but for some reason never got them. I think it was not knowing how I could hook it up properly.
Anyone know A) The type of connectors use on the existing ('01) oil cooler lines and B) where I can get a very short oil line to hook this unit up?
an6 iirc, and build it yourself - ballerbolts has the things you need.
