    temp reading

    Hi all,I am a proud owner of a 2001 mille as of yesterday and I have noticed that the engine warms up quickly,whenriding it reads 74-77 degrees,and if I am stuck at traffic light's it rises quickly to about 92,then when I pull off I get a bit of smoke out of the exhaust then its fine,any ideas to what it could be? Thanks

    normal operating temperature for mine is 72/73 and the fans come on at 94/95. What colour is the smoke and what does the oil level/oil look like ?

    I would say when riding mine is at the same temp as yours,it seems to get up to 70 degrees quick and around a minute stopped at traffic lights it shoots up to 92 degrees when I pull off,a puff of black smoke then its clear,oil is between both marks,but I haven't looked at the colour of the oil

    Hi mate, i have a gen 2 RSVR rather than a gen 1, but your temps sound pretty similar to mine, when riding normally the temp is usually around 78 -81C, but when stopped at traffic lights usually rises up to 87 - 90C, if it's a hot day maybe even up to 94C

    The passage below is taken from the RSVR handbook, hope it puts your mind at ease a little.

    The coolant temperature display reads " - - -" when the sensor detects a temperature below 34C (93F). When the sensor detects a temperature between 35C (95F) and 114C (237F), the display provides actual temperature indication. Temperatures between 115 C (239 F) and 135C (275F) are displayed with a flashing indication. In addition, the warning light will come on to indicate a dangerous condition. The display will flash for temperatures above 135C (275F) (again, the warning light comes on).

    Puff of black smoke could be one of 2 things, its running very rich or you have oil in the airbox and its being pulled through the engine.

    Check the little site tube on the airfilter housing to see how full it is.

    Hi again I have checked the pipe,no oil in it,so could it be running rich,if so how do I lean the mixture,also when I smell the exhaust when its at 90 degrees it smells like the oil is burning too hot? Any ideas thanks

    What I forgot to say it that its also worth checking inside the airbox for oil as well (not just the site tube)!

    From what I remember (so its worth getting it confirmed with Griff) but white smoke = oil/failed gasket, black smoke = rich

    Is it only when you pull away or during down changes/on the overun ?, this could indicate valve seals

    But bottom line is check with Griff.

    Ok will check air box ,when riding there is no smoke,just when I stop at traffic light's,when the temp gets up to 92 degree then when I pull off,giving it throttle I get a puff of black smoke out the exhaust and that's it,then the temp starts going back to normal 73/74

    hello.

    My normal temperature during riding is 75c, but my frends it's only 68. Is thermostat "dead"?

    regards.

    Hi Guys,

    The normal running tempreture here in a Tropical Country will be around 77c-81c while on highway and 81c-97c on traffic stops ( 97c is when the fan kicks in).

    Mine once reached till 112c due to a massive road cogestion (fans was running as well) but never more than that.

    there are 3 ways to make the tempreture lower based on my limited knowledge.

    1. Change to the AF1 after market 65c thermostat. I was told that this will bring down by about +/- 2c-5c while running. but will end up the same tempreture when the engine is hot. Note that there are also comments that I have heard before that the engine does not run so good at low temp.

    2. Water Wetter, a special type of coolent that give about 2c-5c less hotter than normal running temp. (pricey)

    3. Slightly bigger and faster fans, I did this before on my CBR F2 600, but I have yet to find time to modify one to my RSV... typically it can dissipate heat quickly but at the cost of more voltage consumption. not good if you have a problematic stator and/or battery.

    hope this helps

    I've been using my bike to and from work lately, when it's been warm (outside temperature maybe around 18C-21C)
    It's slow riding, barely above 50mph.
    But the temp is normally showing well into the 80s.
    Presume this is normal for slow-type riding where it's not getting enough air flow?
    The heat coming out of the fairing is something new to me!

    Hi Bro,

    Sounds right.

    Here in Malaysia the standard weather tempreture is about 28c-34c. If I were to do slow riding around 50mph the temp should show around 85c-87c.

    The heat from the fairing is normal, it's good when you are riding on a rainy day... (balls warmer, hahahahah)
