Thanks Macca and thanks Pleiades for your info, appreciate you both willing to assist me in my quest to ride comfortably. Will do some resistance testing, maybe a ride comparo and will keep you posted, cheers, Brad

For the benefit of anyone who has fitted (or is intending to fit) a temperature gauge I did two tests this weekend on the XTZ to draw up a comparison table between the temperatures read on the gauge and those read from the ECT sensor by the ECU to give some sort of idea as to the accuracy of a temperature gauge.

The bike was left to idle until the fan cut in and then out again and the temperatures were read at intervals on the diagnostic tool and the gauge and elapsed time recorded.

The first test shows what happens with AIS connected and functioning normally, the second with the AIS blocked.

The first noticeable thing is that the temperature gauge reads fractionally lower than the ECU does up until the point at which the thermostat opens, there after is reads slightly higher, which is kind of what you'd expect as the gauge sender is after the ECT sensor in the cooling circuit. The biggest margin of difference is detected at the top end of the temperature range.

The second point of note is that when the AIS is disconnected the bike takes longer to warm up at idle up to about 60C, at which point the two test's results are similar. With the AIS blocked it takes almost a minute longer to reach 60C.

The fan in both tests took just over a minute to bring the temperature down the level where it cuts out.

Obviously there are a number of factors which would vary from one bike to another (mods, coolant mix, fuel, climate, ambient temperature etc.), but the results should be fairly representative of how the cooling system behaves on an XT. In fact, when Schnidely tested his bike, he got exactly the same results on the gauge for the fan cut in/cut out temperatures, and only fractionally longer for the fan cycle at 24C ambient.

SOLD the XTX for a Super Ten 1200. And just bought a Raptor 700 so staying on here for some tips....

I am most definitely very thankful for the extent to which Pleiades has gone to help me both on and off line.

I now know my engine temp is normal so a test ride on another scoot should determine whether it's unique to my bike or not.

Will keep you posted

Cheers

Ok UPDATE time

Managed to take another Tenere for a ride to compare my previously mentioned engine heat issues. To my astonishment it was exactly the same as mine. Heat coming from both sides around the ankle to knee area, worse on the header side(LHS).

Not there real bad sometimes but other times enough to feel the sting from heat with jeans on.

At least I now know my bike does not have a unique problem, but does have a problem in my world.

Next step is to try and divert the heat away from me. I know the big KTMs are bad for engine heat not escaping which people seem to be in agreeance with but no one else has mentioned this about their Ten....hmmm....maybe I'm getting fussy in my later years

Glad you've established it's not the bike - you should be able to sleep a little easier now!

Kevlar lined jeans work well at insulating your legs from radiated heat...
