Temp Guage

[uk9876]

HI new to the forum and the GRT just quick a few  questions to the members, my  bike is  brand new well all most Ex demo with 250 miles and 2.5 K of the price tag.

1:-  Temperature Gauge :- Should it get to say 3 bars then  stay there whether  you are in traffic or on the open motorway or does it go up and down depending on the road conditions. If i am say on a motorway at a constant 70MPH it will fall back to 1 bar when i get into town it will start to rise to 2 and 3 bar then drop back to 1 when i get on the open road again. Only reason i ask is my PAN did this as it was the thermostat  that was stuck open.

2 What should the RPM be at tick over when idling  mine can be anything from 1500 to 2000 again this could be due to a stuck thermostat as the engine is not getting up to the correct temperature so idling high.


Any help would be great Before I go back to the dealer.

Hi. Your temperature gauge sounds like it is operating just fine. If it gets excessively hot in such a way that there is a fault somewhere it brings up a warning message. I have never seen the warning message but there is some info in the handbook about it. The gauge may even perfectly normally go upto full bars, that's still fine.

Tickover...... much too high. Should be about 1100rpm. You can alter it yourself from the screw dial on the nearside of the bike.

+1 sounds like your temp guage is working just fine. On the motorway there is plenty of air flowing through the radiator and therefore the temp guage will come down. When in town or slow moving traffic there is less air flowing through the radiator therefore the temp guauge will go up, at some point the fan will kick in.

Kind regards

Temp guage is fine. That's how they work on GTR
Tick over should be around 1100 to 1300

My bike is the same Temp wise, as the rest say its normal. What I have found with tickover is that with the Eco off its about 1200. With Eco on it sits 13-1500. Just switching it on and off when stationary in traffic causes it to rise and fall by a few hundred revs. I assume that as Eco leans it off, fine for cruising, the idle goes up to compensate for the lean mixture. It is very obvious when you do it. Also found that with Eco on in town and doing slow riding the bike isnt as smooth as with it off, lean mixture again no doubt. I now leave it off in town and put it on in the nationals when out for a commute or potter.

Ever since my radiator leak and the subsequent fitting of the rad guard, the guage is one notch higher. It means the fan comes on more often. I might buy the aluminum fans as they are supposed to cool everything down quickly.

- yeah , on my GTR , the temp gauge is most "lively" .

- i had her idling for a while in the garage the first day i brought her home from the dealer and wasn't really paying attention ... then had a look at the dash and the temp-bars were full right to the top (!!).

- shut her down right quick and scurried to read the manual.

- learnt that : (a) don't idle too long , and (b) when it gets really hot there is a warning sign on the display.

Genearly speaking a Rad guard does seem to effect the cooling, it has done on most bikes that i have owned and fitted on too.... The Tuono, which has a numbered temp guage rather than bars runs, 5deg hotter with the rad guard on.

Pistole,

I think you need to double check that the fans are working. My fans come on just after the gauge hits 3 bars, and it never, ever goes higher than three bars no matter how hot or stationary the conditions.

I am also fairly sure that the dash flashes up a "Too Hot" type message if the bike does overheat. Sure I remember reading that in the manual, though never seen it in action.

+1 on what Martin says. The fan kicks at 3 bars. I've had mine idling for ages in hot weather and the fan always kicks in

[pistole]

- the fans kick in and brings the temps back to "normal".

- have noticed that if you shut down just as she's peaking with heat soak , the temps will actually continue to rise a bit.

What's "heat soak"  ?

[Rusty]

"Heat Soak" is basically the metal of the engine being warmed up by the combustion and burning of petrol that gives off heat which is absorbed into the metal of the surround ...... if you then remove that source, ie .. switch off the engine the metal will still be hot and may even increase in temperature for a short time as the metal is "soaked" in heat ... after time it will naturally cool.
Hope that's clear !

I was out on my bike today and it ran at 4 bars all of the time, on the Motorway, stuck in traffic, and having some fun in the lanes. I have got a rad guard and when stuck in traffic the fans were on a lot of the time. It was 26c today in Kent and 4 bars was the norm, my bike is a 2007 with 20k on the clock.

32 deg ride today, rad temp is 3 or 4 bars when on the move and i can hear the fans kicking in while we are moving. when in traffic in these temps the temps bars rise all the way to the top but do not get any warning messages. The fans are busy on this bike even in 15 deg temps but the bike always seems to deal with the temps.
If living in these higher temps maybe id consider running a 100% coolant mix to aid its cooling .
