Oil Filler Plug / Engine heat

I replaced the stock plastic oil filler plug with a nice metal one. Looks, good, but I hadn't thought about how hot they'd get. I guess that's why Ducati uses the plastic in the first place. As a related matter, how hot are your bikes running. Mine got up to about 240 f. bringing it home from the dealer. Seems kind of hot to me. My harley, with no oil cooler, seemed to run no hotter than that. Also, today I seemed to notice a fair amount of heat at my left leg. Nothing crazy, but I hadn't noticed it before. Just asking a lot of questions as my bike's new and I don't have any experience with Ducatis. Thanks much.

That doesn't sound bad. When I bought my bike, I went back and talked to the mechanic about what to expect with the machine, and he told me not to freak out when I saw the temp gauge get real high, that it's normal. Said since it is reading oil temp and not water, that customers think it is overheating when they see the temp on the display. And I live in Las Vegas and have had no problems. You're good to go.

FYI, not that you'd want to see it, but the oil temp display doesn't read "HI" until over 338 degrees F.

Stuck in traffic mine has gone as high as 135C, which is about 275F. Freaked me out a bit, but I was told not to worry. Cools off pretty quick once moving, too. It's hot here and daytime I'm usually around 105C or 221F when I ride around town, commuting. Evenings it usually doesnt go above 100C, 212F. (No, I'm not a math genius, using an online converter)

The oil temperature indication was occasionally causing a minor freak out with me, as well. I just switch the window to the clock mode after the engine reaches operating temperature. No more "high" temp indication. Ah, blissfull ignorance! The bike basically can't get hot enough for any damage to take place, assuming the presence of oil and a good oil pump. That's what the oil pressure idiot light is for.

As I've never had a copper oil drain crush washer fail, that's what I use.

Mine gets to 220 or so in normal riding in hot weather. Stuck in traffic, will go to 275 or so. At around 250-255, sitting still in traffic or a light, the engine makes louder sounds (like belts etc type noise). Goes away at under 250.

In any case, I baby it a bit - if its over 275-280, I'll pull over for a snack and let her cool a bit.

Curious about engine noise, do any of your bikes sound (or seem) different when it gets to such high temps?

Oh yes mine rattles like a bastard when I'm up in desert temps.

When I'm up at around 130 degrees C, so about 265 F, it's sounds like my ancient diesel Jetta. So I stop, have a bit to eat, start it up it sounds like a dream and off I go again.

No temperature problems at all, I've never seen the Hi warning message

What really freaks me out is, in winter (we have pretty cold winters in my region), when my bike hardly reaches 60ºC (140 ºF). Has it ever happened to you? Has anybody tried to avoid it covering the oil filter?

Yes, people have mentioned covering the oil cooler with tape or something else during the cold seasons. I'm definitely going to do that after summer, as it sometimes takes 10-15 minutes to get above "LO" temp.

I wonder how hard/ill-advised it would be to plumb in a bypass circuit behind the oil cooler to take it out of the loop entirely.
