Cooling!

[RED CAT]

Noticed while in Moab a couple of weeks ago that the fan on my S10 was on alot while jeep trail riding. Temps were mostly over 200F unless I got on the really fast stuff. Also took quite a while to cool down once hot. A pal on his GS800 said his fan didn't come on all. I think the design of the S10s rad completely enclosed and on the side is not condusive to good cooling. Good protection from rocks though. Maybe more capiicity might help. Anyhow, I think Yamaha could make that improvement down the road. Have heard others mention on here about slow riding and constant fan work. The fan did however manage to keep it out of the danger zone.

Unless the heat pounds your left leg like it does for some, it's a good thing that it's on. I think it'd take a pretty radical design change to incorporate a different radiator orientation/location. When I've got the left fairing off, I don't think it'd be conducive to a larger radiator.

What might work, though, is something like the Thermo-bob for the KLR. I'm not sure of the thermostat size in the S10, but with the KLR thermobob it's a housing that encloses a lower temp automotive thermostat.

Something to think about...

So, you're complaining that the radiator did its job of keeping your bike cool by the fan turning on? Uhh, ok.

A bigger tank will still get hot just as the one we have under the same conditions. A bigger tank will weigh more and take more space. It's a balance act between many variables.

I'll take what Yamaha gave us over what I dealt with over at BMW any day.

This may be viewed as harsh by some, even many, but I really fail to see the logic in complaining about something that works. I've ridden my bike in conditions that have had the fan cycling for hours on end with no ill effects.

Ride more, worry less.....

yes if the radiator was like it is on most bikes we would all have to buy guards that cost 100 bucks and would all be complaining about a rock gettin fliped up and making a pin whole in the radaitor, or how we droped the bike and it crushed the corner of the radiator.
have you heard that on this forum? and im sure not as many bugs get stuck in the radiator this way.

also in the cooler temps the left fairing is a hand warmer when riding! for the left hand only tho =/

Here's what I was talking about from watt-man re: the Thermo-Bob. I've not had any concerns with cooling, so I haven't really given it too much thought.

It worked beautifully on my KLR, but again, I'm not sure how the cooling system would benefit on the S10...

Did several hours of off road, dirt, gravel and other such unimproved road or trail services this weekend. The fan cycled and ran just fine. never felt the bike of was jeopardy at any time. It does a great job and is out of harms way for the most part.

Around labor day last year I pulled the commute from hell and did well over 90 minutes of 1st gear stop and go at 104F with the intake air temp showing 115F or more. Water temp went to 226, fan came on, water temp went down, fan went off. Wash, rinse, repeat. Got a couple of curiosity looks from cagers about the sound but the system worked fine. Sometimes when the fan was running, the hot air would waft my way, but was better than similar ventures on the KLR.

Shoulda been in Austin traffic yesterday. Mile long waits at traffic lights. Had that fan on-off cycling for a long time. Well designed and very predictable, if you ask me.

Need a fan to move the air when the bike ain't.

Karson,
It sounds to me like that thermo-bob is designed for bikes that run too cool in cold weather. Since the Tenere issue is excessive heat when going slowly, or stopped, before the fan comes on, and since the thermostat is wide open by then, it wouldn't matter what type of thermostat was in there. The only resolution I can see for people that are annoyed by this situation is to have a remote fan switch so it can be turned on at will so you don't have to wait for the temp to get into the mid 220's before the fan comes on automatically.

Not complaining, just an observation. No doubt it works well but does heat up easily.

it's because you ride it like you stole it! ::014::
mind you that would be good for the cooling.. more speed, more air movement.
Dang. got myself confused.

When we were crawling through San Fran, trying to get south through the city (hwy 1) the fan kicked on a few times, right around the 200 Deg. F mark. once it dropped to 200 or less it kicked off. Worked well, tell you the truth, never noticed the heat off it.
could be worse, you could have been on a ST1300 or an FJR, now those throw heat. Dang got off subject again. ::009::

On mine it is cycling between 100C and 105C. That's a pretty close range. While having the radiator out in the front would have made the slow speed "natural" cooling better, it also other problems, like mud that is not going to go away soon. Had that problem on the Strom a few times, with guard, and once the crap is in there it takes away from the cooling efficiency until it is thoroughly cleaned. Bugs, wings, dirt, sand all build up a lot faster in the fins of a front mount.

We have a cooling fan ? I thought that was a Air Raid Siren ! ::021::

This is a mute point on this bike, the system is more the adequate to handle some pretty diverse conditions. If you want to ride a bike you have to worry about constantly overheating even in cool weather, hop on a A990. Mine ran so hot, I installed a second fan and a cooler temp switch to kick them on. That bike would shut itself down when it got too hot, which happened a few times before I installed the second fan.

The day I picked my bike up I only road about a mile before stopping for lunch. While cruising slow through the parking lot I heard a fire siren and stopped to look around for any firetrucks coming by. It took an embarrassing amount of time to realize it was the cooling fan.
I have noticed the engine seems to warm up to fan temp very quickly, but the fan seems to do a fine job of cooling. I think the engineering of the cooling system is one of the innovative pluses of this bike but will no doubt cause the fan to run more often than other bikes

Amen & Hallelujah to everything Firefight911 said! ::012::

I just don't get it, but it seems quite a few folks just go hunting, searching, and looking for something to grumble about regarding the Super Tenere. Here the cooling system does *EXACTLY* what it's designed to do, in *EXACTLY* the manner it's supposed to - i.e. maintain the engine's operating temperature in a relatively narrow range that's optimal for its proper functioning - and there's those that somehow think it should it differently...

Other manufacturers have used alternative radiator placements like the S-10 has (Honda immediately comes to mind with their VTR's and VFR's), and those have worked well, but the cooling system on the Super Tenere seems to function *EXCEPTIONALLY* well from a cooling standpoint, and all while being wonderfully well protected and remaining remarkably bug-free and devoid of rock and stone damage.

Next thing ya' know folks will be upset that the bike's final drive doesn't ever break...

I agree that this bike is designed fantastically well/efficient for an adventure bike and you get a lot of bang for your buck IMO. I think this place sometimes is rather quiet just because we run out of things to talk about, and if we were in person, we'd just be sitting across from each other looking at each other seeing who falls asleep first. Heck, just wander over to the advrider big thread and start reading from page one. There has to be 50 different tangent conversations that've taken place; folks just run out of questions/concerns about this bike! Saying how great it is over and over isn't conducive to a forum/thread staying alive long. ::008::


There really are very few, if any, true shortcomings of this bike that cannot be easily remedied. Maybe that's because it's only been around for a few years and only time will really tell? Who knows...


With regards to the cooling system, other than the occasional thread/post about the heat on their left hand leg, it's been quiet.
