All- the Thermo-Bob thread reminded me that in the coolness of the far NorCal coast it takes forever for my A13 to warm up. I'm just another theoretical non-Thermo-Bob user, but I can't see the higher operating temps with the Thermo-Bob as a good thing. However, I am attracted by the prospect of faster warmups. And so the question: How to get faster warmups without higher operating temp?

James-and others, Now you make me scratch my head. I don't believe you can get faster warmups without a higher operating temp--unless you use a block heater. smile. Isn't all that 'connected', faster warmups and higher operating temps? You can get faster warmups (higher water temps!) by using a 'card' between the screen and the radiator and restrict air flow. I did that last fall on my KLX300R when I wanted to change the oil and the OAT was 38F. I blocked off the radiator and the water + oil temp followed right along behind it. Or you could just install a thermo-bob and have 195F water around your piston pretty quick. Some say less than 3 minutes. shrug. More like 3.2 minutes. I have enjoyed the, uh, heated discussion: The significant 'fact' that is missing from all this thermo bob discussion is the ideal operating temp of a water cooled internal combustion engine (ICE). All my life, I have been taught/led to believe/or lied too (shrug) that 195F was the optimum temp for an water cooled ICE. The T-Bob does that quickly and efficiently. If my ( & Watt-man) premise is correct, what 'looks' like a higher operating temp is actually the correct operating temp. Several have commented on the price points; and I agree, if you don't intend to keep the bike long it is not a good investment for you. Equally so, if all you do is ride to wally world, then proper footpegs, farkle ad-nauseum is pointless. Fun, but pointless. shrug. I am a long-term keeper of stuff = the KLR, and so, I drank the science-laced koolaid because I believe it will benefit the long term future of the bike. Particular in the area of keeping the cylinder round through bringing the entire cylinder to a proper/uniform temp (a heretofore unmentioned benefit). An earlier post correctly surmised the problem of thermal cycling/shockcoooling in aircraft motors, which is problematic to us as well, that most of the motorcycling community [for the most part completely] ignores. smile. shrug, or frown; your choice. And was happy with the price-point and the flavor. I ride at the lower end of the temps and believe it will help the bikes longevity. Admittedly, it may not make as much difference in SoCal/SoTejas. shrug. I hope I never go there to find out! wink. I believe Jeff K is correct that the oil temp is 'higher' but not so much that it is out of the correct operating limits for the engine or the oil. Perhaps the community would benefit from the 'K' mod = an oil cooler (bypass equipped of course). We installed such a device on a 48'Panhead-chopper in the 70's. It was the power-steering cooler from a FORD application. Looked nice and worked perfectly. In the end, we all make a choice, what to believe and what will be the end results becuase of our action/inaction. One thing is certain, if you don't ride the bike, the gas goes stale and that leads to a whole lot of other problems. Yeah, ask me how I know.... revmaaatin. who is 3x thermobob end-user: because 1/2+ of the riding season IS below 60F.

Buy a Honda or any other motorcycle that uses the same bypass system (though stock) as the Thermo-bob. You want high operating temperaatures? Come to the Sacramento Valley and stop at a 5 minute red light. Fan or not you will peg the temp gauge, over and over again. You won't with a Thermo-bob. Tim

So, explain to me then exactly how a thermo-bob improves cooling when idling at a stop light. I don't even think Watt-Man will say that his product does that, unless the radiator fan is already running because your water temp is already higher. A radiator bypass can DECREASE the amount of cooling but it can do nothing to INCREASE that amount. If so, rigging a handlebar switch to keep your fan running all the time would accomplish the same thing for about $6.95. -Jeff Khoury

operating temp? Add a bypass and don t allow coolant through the radiator when warming up. That s the idea of the T-bob of course, they re available in 180F as well maybe that would help your concerns. My overall view is the goal, year round, is 195F water, 200F oil. But I do not buy in to the hotter is worse angle when your oil is 160F and the coolant is 160F. Hotter is better in those cases. Watt-man [Non-text portions of this message have been removed]

I think you must add a dash of ThermoBob and a touch of freshly drained used oil :> ________________________________ From: eddie To: KLR650 list DSN_KLR650@yahoogroups.com> Sent: Wed, June 22, 2011 5:24:48 PM Subject: [DSN_KLR650] NKLR.
