This temperature topic comes up quite often.
The whole Yamaha gauge cluster on the Tenere is a sort of messed up deal in my opinion on both generations.
At first I worried about the high temperature readings when riding in hot weather but after finding out everyone else was seeing about the same thing I quit worrying and haven’t had any heat related problems in over 63,000 miles.

I've had pretty good luck finding parts by just googling the part number. Sometimes the parts show up in unexpected places. Ron Ayers Motorsports (and perhaps other sites) lets you do a reverse "where used" search on the part number. That can be helpful to broaden your search criteria. For example on my Honda ST1300 I found out the MAP sensor was the same as on several other Honda models, so I could add those to my search terms on ebay, etc.

Oh wow, that is a great resource! Thanks WJB

It was running at 170 down the interstate which was great of course but when I started down some back roads the temperature started to climb into the 180's then 190's, back down to the 180's and it kept up that scenario for a while. What concerned me was when I began stopping in traffic and the fan would come on (215-220 on my bike), which is normal but then it never cooled off when moving again, staying in the high 190's to 200 range. The further I rode the less and less the bike was cooling off. So I checked the radiator inlet for a goose or some other obstruction :) but it was clear as was the radiator core. So I narrowed it down to a sensor or t stat. I can test the t stat not so much the sensor.

Just a quick question for you, am I correct in thinking that the temperatures you have quoted here are in Fahrenheit? Because if they are, then I think your thermostat is working just fine.

Here in U.K., we get rather cooler temperatures than you enjoy and your figures look to be the equivalent of my own figures in Celsius, even to the fan coming on in traffic. I don’t think you have anything to worry about.

While the temps seen aren't particularly out of line, he mentioned irregular issues and has physically tested the thermostat and seen irregular behavior. I'd be replacing it too if it tested the way he has indicated.

Rather annoying that the OE part is not available and excessively expensive for what it is. I look forward to reading someone has found an alternative part. Maybe I'll look into that myself when I get some time.

Don’t remove it completely, rip the center out and reinstall the remaining t-stat as a restrictor. Old backwoods race car trick, wouldn’t hesitate to do it and cross the country tomorrow.

I'm in Ft Lauderdale , mine will get up to 220 but will cool down with the fans and riding a while.. with that said do what we do to cars and air boats that run hi RPM , drill a couple small holes around the stat and reinstall it . This will keep the temp down if the Rad is doing its job. The top of the rad to the bottom will only be about a 15 -18 degree difference. Use a heat gun to ck the temp in various places ,hopefully it will not just keep getting hotter because of content flow , thats what i would try , not much to lose . just keep an eye on that temp !!
