It's a hard life for a tuned two valver in climates ranging from struggling to get above "Lo" in the 40's to trackdays in the 100's.
I've been thinking about blocking it off in cold weather, but I'm too lazy to bother if it's not a simple knob or switch.
There's the larger cooler alternative for hot weather, but I was thinking about two stock coolers - one or both with some sort of cut-off....
Ideas?
NCR makes a larger oil cooler. You can buy a grill for it and then do what i do. tape it off. works pretty well, sometimes it will take 20 minutes to get it to read 120, and it wont go over 150.
but i also swap to 00 oil too.
This winter I am going to try putting some foil tape over it to get some warmer temps. I am thinking one 3" strip down the center will do the trick. If that doesn't work then some 1" wide strips and just peel away until I can find a good balance.
During the summer my temps are just fine in our > 100°F heat.
The dual stock cooler approach has been around for a long time.
Possibly the cheapest way to go.
In the past, there were thermostat valves available, they attached at the engine, and the stock( or shorter?) lines attached to it.
I would think a moderately talented seamstress could sew up a nice cover with velcro straps.
The old MTS was famous for never getting out of 'Lo' in cold weather.
I would just place black ductape over the front of my oil cooler in the winter. It worked very well, and you didn't really notice it since the cooler was black.

, but no longer?
I'm actually more worried about the high temps over a high revving Alp pass or during a long warm track day.
(my 50'K heads are warped from this and when/if I replace them I would like to avoid it in the future)
Any oil line petcocks available? (for a second cooler)

Unfortunately, it's rather large and not very handsome.
I go high class and use HEAVY DUTY al foil on mine when it's cold. Allows for infinite adjustments by tearing bits off
I'll check out mounting options for a second cooler, maybe an S4R under the head.
A dual set up with one or two valves means a lot of plumbing :-\
JAGG has one manual and one automatic http://www.jagg.com/by-pass.htm (http://www.jagg.com/by-pass.htm)
The plumbing would be less ugly with only one larger cooler and an automatic thermostat/by-pass valve.
My concern with those is that they're set up for hose clamps.
Here's a bit better one, it's got threaded ports to put fittings in:

^^ damn, that's ugly! Cool 8)
Hose clamps no good for this?
Is that a lower inpsection cover w cooler mount from a MH900?

Hose clamps apparently were good enough for Evoluzione. Here's their kit for the Aprilia RSVR:
~~~SNIP~~~
And yet you used steel AN fittings. ;D
Anyone know about Febur dealers? Or I could go for a SC Project cooler...
what about just getting a larger cooler for hot days, and fitting some on/off valves before the lines at the engine?
something like this might work... but looks like it would block the other fitting :/

It was speculated that the Evoluzione restricted oil flow by about 10% when fully open.
Is that acceptable?

You can order from SC abd Febur directly

@ Corey
I think it has to be a by-pass valve to allow oil flow to maintain oil pressure. Like Jagg or Pegasus.
@ Raux
Thanks - that should work
@ DP
If the surface area is, let's say 50-100% larger, I speculate that it will still be 'enough'. Can't remember which of them, but they claim a reduction of 10-12 degrees Celsius (~20F?). For my application it wouldn't hurt with a little more, but then I'd probably need two coolers and it requires a lot of plumbing if I also wanted by-pass valves on both.
I didn't think I would need more cooling, but I do. It must be because of the high degree of tuning. It's not the first or second time out on the track - it's the third and on, when the engine hasn't had time to cool off properly OR speeding on the highway with an already warm engine OR a 20 mile mountain pass...
I've been reading the huge Setrab catalog and thinking about location, fittings, brackets a.s.o.
Then my eyes started bleeding and I wanted to look for easier solutions.
The HM Evo cooler has a core almost twice the size of my stock HM.
Plumbing is easy, I think it fits and WOW it's $350 cheaper than an imported SC Project or Febur!!!
The Permacool thermostat I bought didn't work.
Speculation is that it, even in the 'warm position', flows too much oil and very little travels through the narrower cooler passages. Probably ok for a car with three, four or five times our oil flow...
I'm back to stock, but with plans to mount my HM Evo cooler - hanging under the horizontal head - partially covered for cold days.
While we are on the subject I'm going to apologetically thread jack.
Why are there oil coolers on some models like the classic monsters and no coolers on others like the 696 and 796? I would argue that engine size matters but I have seen all sorts of large cc bikes without oil coolers. And then some smaller bikes with them.
Sure, you benefit from being able to hold a bit more capacity but I'm at a loss as to the inconsistency of their use as well as their effectiveness.
Correct me if I'm wrong, (most often I am :) ) but doesn't current synth oil have a very high breakdown point? Something like 300 degrees or more? If your motor gets up past that, no cooler will help a damn. Also, a cooler doesn't work when you're not moving, when its most needed. Flying down the highway it becomes pointless.
Am I way off here?
