Temp gauge trouble shooting

[declan]

@dan28 no thank you mate I'm running my cheap temp gauge for now I've gotta focus on re painting my tank and new rear fender

[Calum]

Never heard of them going wrong personally, DTRE doesn't have a temp gauge so it's never been an issue for me.

They get hot but they keep running.

You can get a temp sender for the vapor that screws in where the original goes. That's what I did so I have a nice reading on my unit.

@calum I've got the one that sits in between the radiator fins

[Jens Eskildsen]

120x120mm fan fits, i mounted one from a pc as a test.
Makes removal of the sparkplug a slightly bigger hassle

[Calum]

Don't imagine it being terribly waterproof mind you.

I wonder how effective it actually is. Having run a liquid cooled computer, and know the temperatures a chip can reach.

What are your thoughts?

Good, bad?

[declan]

@calum I'm guessing any advantage is just that an advantage so I'm probs gotta run one and thank you Jens I'm sure those dimesions will be a life saver

[Calum]

@declan How are you going to wire it in? Personally I would want it kicking in at certain temperatures. Like on a car

[finnerz89]

Trailtech do kits that are controlled with temp etc

[declan]

@calum run it from the battery on a switch so I can choose when I use it

@jens-eskildsen sorry to be the one to tell you this, but for one, you have the fan blowing the radiator the wrong way, rendering it useless as soon as you start to move

secondly, pc fans are useless in vehicle application, they offer literally nowhere near the amount of airflow that moving even at 5mph provides. typically a PC is generating 150w of heat or less, thats 0.15kw, whereas a bike such as this is making hundreds of times more heat.

you need an automotive fan to make an ounce of difference

[terry.tz]

wow hahahahahahaha
@declan it probably the same one for other motors so could pick one up for £5 ish maybe measure the thread and ask sellers ect don't worry about the connection that's easy fix you probably have some old connector around

[Calum]

@tunertom You can pull air through the radiator no problems.

[finnerz89]

@tunertom the fan on my triumph is behind the radiator, as is the one on my aprilia.

[Jens Eskildsen]

Tom, I know, as I said, it was a test to see if it would fit.
Its mounted on the right side tho, and its supposed to suck air, not blow it, so it pulls air through the radiator.

[declan]

@jens-eskildsen yeah in my mechanics course we were told that some fans suck air through the radiator fins and others blow it through guess it doesent really matter

[Jens Eskildsen]

Fan is protected a bit by fitting it on the backside

[declan]

@jens-eskildsen but it's harder to fit and gets in the way more and then you can't see it

[tunertom]

youve got the fan blowing towards the front of the bike... i didnt say it was in the wrong place i said its massively underpowered for application and its blowing the wrong way, its fighting the direction of the wind!

as you can see..

And I answered "I know that", and described in detail that it was only a testfitting.
I got it for free, and now have the wiring sorted for a proper fan, and know what dimension will fit.
Lets move along, shall we?

wouldnt a tape measure or an engineers rule, to measure the width of the radiator core not been sufficient to see what size of automotive fan you need, be better than bodging computer components onto it?
