KLR650 Temperature Comparison - How Hot Is TOO Hot? This video show a comparison of the factory temperature gauge with a digital gauge I recently installed. I was tired of just wondering how hot the bike was and this video lets you know about what to expect on yours.
The temperature gauge I installed is from Trail Tech and a full install video can be seen here: • How To Install A Digit...

Thermo Bob with a cooling fan switch is the ticket. The TB takes all the wild swings out of the running temps and the switch is great at traffic lights in the summer.

Liked your informative video. I have a Trail Tech digital gage on my Gen 3 that I installed with my ThermoBob, and I like always having the coolant temp info as I ride. On a warm day, say 95F, my bike runs between 195F and 215F, depending on what I'm doing. An added bonus I like at the beginning of the ride is: I can see what the ambient temp is before I start the (cold) bike. This is nice for camping or deciding what great to wear.

Appears to me that either Kawasaki didn't use a big enough radiator on these bikes, or thermostat may not be opening all the way. It should cool right down with the electric fan on the bike, and also when you start moving again. Could be worse.......my GL1800 Gold Wing blows air across the radiators from the inside out rather than sucking cool air in from outside. It is why many Wing owners reversed the polarity on the fan motors to get it to pull air in rather than push it out. Honda wasn't thinking on that one! Thanks for an informative video!😎👍

Not sure they are always meaningful! Many years ago I remember reading that the early CBR1000F had a habit of running hot on the gauge, which worried people. Hondas fix for this the following model year was a resistor in the wiring to the temp sensor to lower the reading.

I have the 2006 with the same paint scheme. I put the same kind of windshield on it as you have but 14 in. I brought it back to life with a bunch of OEM parts.

It is an aluminum piston in the steel sleeve just like an automobile. The reason cars had a 12 pound cap on the radiator for a lot of years because they were predicting how hot the engine would run before it blew off. today Many of the cars have 16 pound caps. Water boils at 212° and we cannot let it boil in the engine. This is why we put a 16 pound cap on a radiator. for every one pound of pressure you put water under it raises the boiling point ,.3°. So let’s say there’s a 12 pound cap on my 2023 KLR That means they knew that engine would hit 248° at some point and of course it’s better to keep it down around 200 but shit happens. It’s not a huge big deal but one thing for sure. Don’t lug. down the RPMs when the temperature is high because I would be asking for detonation which can eventually cause a hole in the piston. as for the high idle, I could only guess but let’s say your idle circuit was a little on the rich side, then, if that extreme heat expanded something and caused a intake leak add air to a feul mixture, which was too rich, thus increasing efficiency and increasing speed.

For the idle it was just a lean factory setting that kept causing it to runaway. After a carb rebuild and backing out the mix it is far more stable on both idle as well as temperature control.

Temperatures in the low 200’s F I would not be too concerned about. Water boils at 212 degrees F at sea level and rises 3 degrees F for every 1 psi pressure rise of the cooling system. So if your cooling system was to run at 10 psi maximum then the boiling point would become 242 degrees F. If the bikes gauge is approaching the ”H” mark and temperature is well up then cool down is needed. The temperature drop across the radiator is a good way of determining the effectiveness of the cooling. Hard to check on a bike of course as stopping and prompt checking with an infrared gun can see small changes that will affect results. As a Cat mechanic cooling system overheating can be complex but “most” hot running generally come down to core plugging, on bikes bugs, dirt accumulation due to dust and wet weather etc. Remove the radiator, thoroughly clean fins externally until no debris can be seen. Fixes many hot running problems. No reason why bikes should not be the same. I hope this helps. Kevin
@BrickHouseBuilds
@BrickHouseBuilds Жыл бұрын
Hey Kevin the radiator has already been off the bike, fully flushed, and I religiously clean the fins before big rides and always make sure its free of debris. I also have water wetter in the system. Again my bike would just get hot and never come down after some hours. Not typical. I did see that 240 mark and felt it started to boil but again I was on a hill and couldn't just let it cool down. Adjusting the fuel mix helped tremendously on multiple fronts.

The lean tendencies when the carb needed a thorough clean probably boosted the temperatures quite a bit. But 240f (so 115C) is way too high for my comfort! Going over 100C is bad enough. Could be interesting to confirm exactly how accurate the small digital gauge is. It is mounted on the pipe from the engine (so after the thermostat?) so I would expect a slightly lower reading than directly from the engine.

Correct the sensor is a bit up the hose from the cylinder head so I expect a few degrees cooler on the digital reading as compared to the cylinder head reading. I discussed that for a moment in my gauge install video

OE thermostat is junk. Little more than an on off switch. You likely notice a wild swing on the temp gage once the fan kicks in. Quite certain the oil burning issue older KLRs have is due to the thermal shock caused by the open/closed nature of the OE thermostat. I installed the Thermobob thermostat since they give you a spare with the Thermobob my brother bought for his KLR. That doesn't cure the slowish warmup but does cure the wild temp swings.

This KLR is almost a dead ringer for mine. I fitted a cooling fan switch after replacing the fan temp sensor and still having a problem with heat. Now mine runs at about a 1/4 on the gauge and if I turn the fan on before it gets too hot when I’m in traffic or off road it will maintain 1/2 on the gauge.

Ok, i was wondering the same thing for my CX 500 adventure bike. What would the temp be in the center of the gauge of a CX, has anybody ever checked? My fan blew up and damaged my radiator, so i replaced it with a cbr500r radiator and fan. The temps seem higher than with the original radiator (in the 185 - 215 range) is this too high for the CX.... I've been dying to ask you this, and its funny that you posted this video with the same question about your KLR.

You are perfectly fine there. CX/GL can run near 220 pretty consistently but that can also vary by where you are taking your measurements. I've used this gauge multiple times and have a buddy with a gl500 and both gauges. If you watch my gl650 first ride/first start videos I believe I show the temp a bunch in there.

i don't believe your temp problem is normal. i have an 07 i bought new and currently have 80,000 miles and never seen mine do that. no matter the outside temp or riding condition when it gets just past half way on gauge the fan kicks on and needle never increases past that point. i have also had couple parts bikes i cobbled together and same thing along with many friends and klr events and never seen what you describe. that high idle at temp is also weird. i recently added a thermo bob to mine which raises temp a bit and still never runs past half way. i would think your fan no working correctly. i also heard a ninja fan is a nice upgrade.
