KLR cooling ability

Iam new to the KLR and wanting to know how it is for low speed trail riding in warmer weather does it have overheating issues or does the little cooling fan work good enough. I just picked up a new 2012 yesterday, can't wait to try it out!

I think the system works pretty good.
The bike is water cooled and the radiator has a fan that is supposed to come on when it gets too warm.

That is until the fan fuse blows for some reason and you better hope you have a spare.

Here we were on a nice day when temps were pushing 90 degrees.
I'm trying to find my fan fuse. Notice we are parked in the shade..

I've ridden my '06 in Phoenix, AZ in July in traffic with no problems. The fan ran a LOT and I just about melted, but the bike temp stayed in operating range.

And I've heard the Gen 2s are a bit better at cooling than the Gen 1s. So barring something going wrong you should be fine.

I have a 2011 and have had no temp issues in any heat or style of riding. Slow trails or heavy stop and go traffic in hundred degree temp. Its all good!

KLR Cooling

I've got an '06 and put the Thermo-Bob on. Have done some backwoods riding and a fair amount of first gear almost-trials riding for several miles and have worried about the engine temp but developed no real issues. The cooling system does like to be "movin' down road" The fan does come on and the temp will increase but have not overheated, though I don't like it getting that hot and I watch the gauge a lot. I guess I'll just have to buy another bike for the woods.(WOW!, what a brilliant idea!) The thermo-bob really helps stabilze the engine when temps are cooler. The thermostat in the thermo-bob kit is bigger than the stock so I would think when fully open allows greater coolant flow. I'm glad I have it.

The cooling is perfectly fine in the stock form........the bob is strictly for those who live in cooler cilmates that want to see higher temps when it's cold out IMHO.....there is a huge marketing scheme behind the bob...IMHO...to each their own......there will be no more flow I don't think just because of the larger stat....it's in there to allow to get a higher temp range. It's an old car stat. The higher temps come from the bypass of the rad nothing else. Look at the system and think about it. No offense to anyone who has one or is thinking of buying one.....it's your bike do as you wish.
BUT...the KLR especially the newer version do not have a over heating issue, they have a much better cooling system than the older version and even that can be regulated with a manual over ride switch. Many of us have installed one to allow us to follow the temps and use the switch to turn the fan on prematurely to help the system before it gets too far up in temps and over power the system.
Research the system and think about what improvements they made....this is one area they made improvements to the new version KLR.

Just saying.

I agree with WILLYS, I too added an override switch in parallel with the existing fan switch to have a more manual control when in tight sections.

KLR cooling

Willys, Yeah I have the thermo-bob for our local climate, from April to late June we can regularly have 40 degree mornings and 70+ afternoons and my morning commute won't warm up the old KLR. I dont like the rapid cooling and heating of a non-bypass system (knowledge from other internal combustion applications) and my bike seems happy with the new system. When I did the switch-over to thermo-bob I did notice that the opening area of the stock stat would be considerably smaller than the automotive-sized one. I have no hard data on this and of course it would take some engineering studies to determine if there is any difference in performance, so I would be "speaking through my shorts" to make any strong claims that it works better. I just use the jungle science approach, bigger hole bigger flow mentality. It would be interesting to actually measure if there is a difference in cooling at higher ambient temp, though I have way too many other projects in life! We carry on regardless.

Hey no problems....I've had this fight before.....it started a war with the bob's designer and the guy who makes them.....you know who they are.....if not ask. IMHO.....the stock KLR worked flawless ly for decades before someone thought of a way to make money......and marketed it perfectly. Maybe it's right maybe it isn't....I don't care personally.......but to sell it on the premise that it must be better because all modern engines have them isn't right. The KLR isn't modern or did it have cooling issues before......if you had a warm up issue or the temps didn't get up to where you liked you either bolcked off the rad with something or.....thought that the stat was holding the heat inside the engine and would allow enough past to allow it to operate......we had no issues with heating or warping of cylinders before this product was mentioned or the idea of it being the magical fix for a problem that didn't exist.
What happened before the bob....? We all rode our bikes and nothing happened to them....did it?

BUT, I'm not going to start a war again....it's not one that can be won....to each their own.....you either agree with it or you don't.....I'm sure you know what side of the fence I stand on.

Enjoy.....
