I am amazed by some of the posts that their bike is not that hot. If I had not used a thermometer on the tank and seat, I would start to doubt myself and the complaints I have had about this bike. Its winter here, meaning that the temp is a cold 65 or 70, so it is easy to tolerate the tank and seat heat. But when it goes back to 90 or a 100, Ill start complaining again. I have 11000 miles on it in the last eight months and getting ready to pull the aircleaner and check the sync on the injectors. Maybe Ill get a mile or two more a gal, but I doubt it. :002:
 

I have three bikes. yes its the warmest, but oneness to ride the bike and enjoy or sell it

Thanks I know about the using the computer to check, but do you have to puul the tank to get to the adjustment screws? Sorry have not gotten around to getting a manual yet. :087:
Yes, but I have not had to do an adjustment as mine has been in spec all along. A note of caution: if you do have to adjust them, it is my understanding that you must use the center cylinder as the reference. I have not looked this up specifically, but I recall a posting a couple of years ago from someone who's TEX was royally screwed up because the service guys did not know this.

Doing the full 20K service with the valve timing did have a significant smoothing effect on my TEX.

Some empirical evidence ...

In an earlier post, I suggested covering the front fairing vents - see
https://www.tiger-explorer.com/index.php/topic,17249.msg210773.html#msg210773

Today I measured the effecting using a thermometer with a probe fixed to the bike at knee height on the left side. The probe was not on frame - secured but dangling free so it measured air temp, not frame temp.

I ran the bike at speeds 60, 70, 80 and 100 kms/hr when the ambient air temperature as 26/27° Celsius, over a total test distance of 40 kms.  There was minimal wind so I didn't need to account for its affect.  Relative humidity 30 to 40%.

Results:
Without the vents covered, the probe measured 14 to 15° C above ambient.  Felt warm but not uncomfortable

With the vents covered, the probe measured 8 to 10°  C above ambient.  Definitely felt cooler and heat buildup was not noticeable.

Hotter wat 100 kms/hr, cooler around 60-80.


Then I tested again when the ambient temperature was 35° C.  The test runs were less scientific, and the benefit seemed less conclusive. With the vents covered it definitely felt cooler possibly due to better airflow.  The thermometer indicated +12-15° covered, +14-15° uncovered. At one stage (slow speeds) the temperature knee level temperature was 51° C - IMO,  proof the Tiger runs too hot for comfort in warmer climates.


Anyway, I will stick with covered vents and convince myself the problem is fixed  :152:

Did you correlate the air temperature with observations of the displayed engine cooling temperature? Just wondering if blocking the air vents has any impact on raising the coolant temperature under really hot circumstances.

The coolant gauge seemed no different to normal - midrange.

If there was any efect it would be to run the engine cooler as more cooler air is being forced downwards over the engine and radiator.

Note - it is NOT the large  radiator extractor vents that are closed - that would certainly cause issues.  The vents closed are those behind the headlights.

Thanks for the clarification.
