Just installed the TTO temp gauge on my quad. Really like how easy it is to install and really like not having to wire anything either.
Ignore my yamaha bars lol
-
egt probe goes in the header pipe close to exhaust port, not sure on the exact distance
but kit should tell you or ask one of the builders.
-
I do a lot of tight trail riding and woods hill climbing with a lot of 1st and 2nd gear riding. I was having overheating issues and did end up opting for a new radiator. I couldn't be happier.
-
So where would you place the probe for this?

If you're really worried about getting your Zilla too hot, get an EGT. By the time your water temp is skyrocketing, your top-end could already be toast. An EGT won't prevent a meltdown either, but it will feed you a more accurate response 20x faster than the water temp will.
This is about as cheap as you can find, but you will need a power source. http://www.ebay.com/itm/DIGITAL-EGT-THERMOMETER-PYROMETER-W-CLAMP-ON-PROBE-/200600832380?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item2eb4bdc97c (http://www.ebay.com/itm/DIGITAL-EGT-THERMOMETER-PYROMETER-W-CLAMP-ON-PROBE-/200600832380?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item2eb4bdc97c)
About the best way to make sure you aren't overheating is to properly jet your bike with a plug chop and do a leakdown test. Air leaks and wrong jetting are probably the biggest top-end killers out there. +k2
Yes an EGT will give you an approximate condition of your jetting. The jetting affects water temperature very little. Water temperature is primarily affected by the amount of power being produced and the air flow THROUGH the radiator.
We have found that the major causes of high coolant temperatures are missing air scopes, after marker grills and corrosion inside the radiators.
If the engine is being worked hard in first and second gear the speeds are too low and the engine will usually overheat in a matter of a couple of minutes or less.
Extra large radiators with air scopes may be required for low speed trail riding. Cooling fans are not options for most two strokes because of their alternators low power output.

So in the 6 days I was riding in Glamis my temp went as high as 220F (and it was only in the low 70's!)
I think its a pipe dream thinking it won't get over 190F
Now where mine is mounted is very close to the exhaust so maybe that makes a difference.
But Bill said he also seen 220F on his so that gave me a bit more peace of mind.
-
On zillas they mount close to the exh pipe and soak lots of heat from there. It would need to be mounted in an area with lots of air flow and away from the exhaust.
not only that but puttng a temp guage down by your feet just doesnt make sense. One of these digital ones or a warp drive seem like the best option.
-
That EGT is pretty nifty though. What kind of values would you even be looking out for on that??
-
And Im not overly worried, I have that big CBR radiator and plan on (hopefully) getting the jetting dialed in good. Im just kind of a numbers guy and want to keep an eye on it and look for patterns and what not with how the motor is running.

Haha hey DMoney I didnt know you hung out over here too lol!! +k2

Oh ok gotcha. Thanks that would have sucked!!
-
19mm is what you need
-
So if I wanted to buy the same temp gauge would I need the 22mm version for the LT500? It comes in a few sizes and I just don't wanna get the wrong one lol.

-
Ive been told they do nothing.
-
How about those inline cooler pieces? Has anyone tried them to aid in the pre-cooling of the coolant? Do they work, and if so which one works well?
-
I've had a trailtech vapor, but I think I might upgrade to this

I run the same one on my hybrid i stuck it just in front of fuel cap on the plastic. alot more convienient than the inline dial gauges cause you dont have to lean off the side to get temp. Im with nopick when it gets close to 190-200 i get nervous
-
That's right. I always cool'er off if I start getting up around 190. No sense pushing my luck on the old beast!
-
just remember when you shut bike off it will climb 10 more deg. 200 is a good place to shut down or run bike against wind to help get it back down.
-
Keep it below 200. Get the coolant above 100 before running it hard at all.
-
Ordered one just now from Dennis Kirk.
So now the next question:
At what temperature does one have to start to worry?
-
That is a way nicer piece than the analog pieces. I've never seen that temp gauge. It's got me thinking.
-
I run the same one you posted. I like it works good and it keeps your max temp for you.
-
At lot of us run temp gauges. It is a great idea. You know the engine is warm before you hammer on it and you know if you are heating up and need to move a little more air through the radiator.
I rode my 250 for 20 years without one but sure like it now that I have one on the Zilla.

Anyone run something like this and is there a need?
