This.

Plus, I hate the look of no radiators, and those weird fins all over the engine



I had an 83 XL600R that would get hot and ping a bit when pushed hard off road in slow conditions, my liquid cooled bikes never have this problem...maybe because they both have fans. I don't "hate" air cooled bikes.

I love air cooled bikes. I just wish they made more "little ones" with fuel injection for us commuters.

Looking back on years of riding and wrenching on air cooled bikes from mini bikes,old Bridgestones and Ducatis to oilheads and everything in between I simply can't recall one failure that can be attributed simply to being aircooled. Most were cases of neglect or abuse ,while the rest were wear and tear.Incorrect jetting being a big culprit.

Never had a problem with air cooled bikes. I started riding British twins in the 60s. My last air cooled bike was a Yamaha FJ1100. It ran great and gave off less heat than the liquid cooled FJR I ride now.

the unknown temperature fluctuations of an air cooled engine contributes to worn out parts more then you think. running very hot and very cool is not good for the internal combustion engine. But I know a couple of deutz air cooled diesel engines that lasted a very long time, under really bad conditions with almost no maintenance. So, it depends.

Being that the bike is still in production after that many birthday cakes has to be some kind of achievement. Is there a liquid cooled bike that has remained virtually unchanged for that long? KLR doesn't count .

The only real issues i've had with air cooled bike has been riding two-up, slow at high altitudes, ie over 6,000 feet.
Had two airheads and two Guzzis.

The newer dual probe fi systems have been a blessing for the newer air-oil cooled bikes.

All life and all in it is a compromise.

How about a make/model/yr./mileage and type of failure to go along with your opinion. (in regards to motorcycles)
I'd like to know whose shitty engineering I should stay away from.

To add:
Cold is also a potential problem.
I ride down to 15F, and around the 20's the carbs on my bikes would experience icing here in the deep and dirty South, thanks, probably, to the dewpoint and relative humidity that, even in winter, is still quite high.
I had this issue on a couple of bikes, but mostly a ZX7 that just would NOT go in the winter.
The Hondas didn't do this. So, I suspect it has more to do with the carbs. But, they also never seemed to come up to temp when it got that cold, regardless of the brand and carb type. I would ride to work with the choke half on and cranked them fully choked, which was really rare.

My K100 was right as the mail at 15F though. One of the few things it did well.

And the Sportster would foul the shit out of the plugs if you didn't baby it even at 80F. It had to idle til it warmed and then you could ride it.
This is, apparently, normal behavior for the carbed pre rubber mount sportsters.

To clarify what this thread is SUPPOSED to be about....

Let's hear stories about bikes you've had that were air or air/oil cooled that actually over overheated and let you down in some way/shape/form....that swayed you towards liquid cooling.
I has not aware that there were air cooled haters, but I don't follow thumpers forum too much.

I despise the oil cooling system on my Honda Falcon. It has two pumps one in the upper reserve/cooling tank and one down in the engine.To get an accurate oil check, you are supposed to warm the bike 5 minutes at idle from cold, shut down & then check. You cannot check the oil during the day w/o letting the bike cool and then doing the 7 minute drill.

The system is for the birds, if they can't keep the system simple, then might as well have a radiator.

Anyways, I don't give much thought over A\C vs h2o. I wouldn't hesitate to get a DR (air/oil) over an XT or KLR (liquid), but I also wouldn't hesitate to get a KTM 690 or 500exc (liquid) over a DR.

So far all my bikes have been aircooled and I've never had a problem. On really hot days the Multistrada throws out a little more heat than I'd like but it's not a big deal. Neither ever overheated or pinged when it was hot. The monster didn't like it when it was cold. Think that had more to do with her being carbed and lean.

really? not an opinion, its a fact. I'm surprised you didn't know that.
you can look for it here about 4/5th down the page.

http://en.wikipedia.org/wiki/Motorcycle_engine

its not shitty engineering, its just cheaper.

.
My Ural is the least temperature sensitive vehicle I have ever owned, 105 deg, -5 deg, wet or dry, it doesn't care and will start instantly every time. It also doesn't seem to mind stop and go traffic as much as some of the other aircooled bikes I have owned, the idle slows down, but it won't ping or miss.

Low tech has it's advantages.

Indeed, it does.

I'm not saying every air cooled bike is crap.
I'm just answering the guy's question with real world examples, which is why he started this thread and what he axed for.
