Thermistor- is it possible to put on bike?

[yzMan34]

Just as the question asks- is it possible? Does anyone know where I can get a small thermistor? I'm sure its possible, the only problems should be weight and mounting and well, finding one. Any thoughts?

I bought one of these for a project that I was working on. But haven't had time to complete the project. I couldn't get them to give me a data sheet for the thermistor they used. But you can do some tests to get ~ numbers for what you will need for equations.

Why??

[yzMan34]

Those sites are pretty cool. The trail tech/ vapor one seems cheesy. when you first go it were you impressed just by the design? I'm thinking they could have done something with an outside metal coating and that connection I'm guessing goes to the trailech/vapor microprocessor? I thinking I would need a NTC for this applicaition

for tempature

Why??

The only thing that comes to mind is that it would be used to activate a cooling fan, or it could be used as a temperature probe.

You might want to visit a heating/cooling supply house to see if they might have something to suit your needs.

I think it would be a good indication if your bike is warmed up properly before riding, also it would tell you if your running the bike in the optimal temperature range, to determine if maybe you are overcooling in winter, or to eliminate the possibility that it's not in the range.

I was thinking of drilling and tapping the side of the cylinder for a probe insertion, thought this would be the most accurate way of reading engine temperature. Running a sensor like the one picture in the link near the cylinder however would probably be just as accurate.

i added a thermostat to my yz250.i think this is one of the best mods for an offroad 2 stroke,bike is always at correct temp with no need to tape off rads.makes jetting easier and more consistant.

Like screnshaw400 said, check out an hvac place.They stock the following.

These 2 may be of use. The cooper 2010 or the 4011. The 4011 can have the plastic removed for a smaller flat surface.

I saw a rad cap with a temp probe in it somewhere in my travels on the net if that would help. Just trying to think where:thinking:

you could throw a trail tech at it, it will show temp of the bike, air temp, timer and tach.....plus a speedo, although I don't know if my speedo works over 35......I can't seem to concentrate on it after that....lol

I'm just looking for something simple. I do need a probe, but obviously a digital readout that is water proof. I just found some NTC ones on the net last night but I'm also considering a thermocouple. I don't know which one would be more accurate/better to use. I could try a refrigeration supply house but i think i could find the same thing on the net, cheaper, or even better of selection.

+1 on this.

I've got one and love it. I let my bike idle for a bit as it warms up and off I go once the temp comes up. Also get speedo, odo, tach, hour meter, etc...

The lights on the top act as shift lights and temp warning lights. You can set what temps and rpms you want these to light at.

Is this thing accurate though? And the shift lights, can you change when they go off?

[secondgear]

You can set everything.

RMPs for shift lights.

Temps for warning, etc..

You can adjust for different wheel sizes as well.

Well thats pretty cool. do you hook it up to the computer? and is it cheap plastic? this thing almost sounds worth buying

Check them out on www.trailtech.com

That's a better place to do research than relying on me to answer all your questions about the features of this product.

haha at least your honest. thanks for the site

The Vapor Speedo from trialtech is definitely worth it. i use it on my street tard wr400f, and it gives me the temp of my coolant, also ambient air (although i gotta say it is off by 10F too high).

The tach is useful also, allows me to see the change in RPM for a given speed when i change sprocket sizes.

also logs the Max temp, rpm, and distance for each ride. nice cuz now i know i can get about 140mi per tank before i need to refuel.

mine has been working flawlessly for the last 3 years. Oh, also the X2 headlight is the bomb. definitely better than the stockers.
