  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

What temp. readings do you see on your TrailTech?

Running with a TrailTech Vapor on my '07 te450, I'm seeing quite a temperature range displayed while riding. (It used to go quite high if I just sat still and idled.) Now that I added a temp. switch comtrolled fan the overheating is held in check automatically, but....I wondered what coolant temperatures other guys see when they ride their bikes.... or sit still? And at what temperatures they switch their fan on to control overheating?

My current auto temp switch cycles on/off at 225/215*F.

(This is measured at radiator inlet.)

Thanks, Dave
 
I think it really matters where you install the temp sensor as well. My TT used to show crazy high numbers on my 08 TXC450 and it was not overheating or spitting fluid. :excuseme:
 
Yeah locations everything...I cut the "water in" hose on the right radiator and put the sensor there. That's also where my temp, switch is so the TrailTech tells me exactly what temoperatures the switch is cycling the fan on and off.

I used a switch from a SV1000 Suzuki ...made a hose fitting bung for it as normally it mounts directly in the Suzuki's radiator.

I just wondered what temperatures guys ..who also monitor "water into the rad." temperatures like to cut their fans on and off at.

I can also manually override the temp switch ... force the fan on or off. If I force it off and wait... sitting and just letting the bike idle...(NO REVVING), the temp continues to climb... and at around 250*F, ( 20psi), the cap lifts a bit and it will start to spit coolant to the catch tank. (BTW, I tested this by temporarily putting adding a pressure guage in the coolant lines).

The same test... if I rev the bike say every 15-20 seconds the water pumps fluxuating speed causes pressure surges and along with the added motor vibration the radiator cap lifts arounf 235* and pressure around 15psi.

All this is held in check with the temp. switch I'm using, turning the fan on at 225* and cooling the thing down to 215* where it turns back off.

I just remember buying/replacing car thermostats ... "stats rated to work at like 195* ... or less.

I'm trying to monitor this on my bike as it is really hot where I ride now ... 210 was the high point today during mid morning riding ... probably 85 degrees during the ride ... Mostly slow street riding to some hammering on some dirt roads ...

What is weird on mine is the current air temperature ... it is almost always over 100 degrees ...
 
Dont have a trailtech but here is some input :excuseme:


I use a temp sensor strip on my engine and When I can see fluid in my overflow the sticker shows around 210. Most fans turn on at 210 so no worries, engines can get very hot before any damage happens.

On scott summers post about the te510 he says that he lost all coolent at a race once and finished half the race with no coolent and the engine was fine minus a few discolored items(but obviously he goes really fast so he had good air cooling)
 
I gotta add my bike hit 261 today in slow traffic-jam riding but the water did not boil over so I'm not too sure what the real temp was ... I'm gonna reset my high temp red light to come on at ~260 or so and the warning light to come on about ~250....
 
I have my sensor just in front of the Y so it measures the temperature of the fluid coming out of the radiator.

I hit 260 on Saturday with no boil over. I was only at that temperature for about 5 minutes while we were cutting in some freshly cut never ridden trail.

On Sunday while racing an enduro, I hit 260 again in some really tight stuff. This time it boiled over and I could taste the engine ice in the air everytime I stopped. I was going to drop out of the race at the 2/3 mark of the race, but my clutch gave out 2 miles before the end of that section. Apparently the Mugura doesn't like being that hot for two hours...
