Temperature Gauges

Calum122 · Guru

So you can see the temperature gauge in the culinder head on the rs. That thing with the cap. Don't know why I thought it was in the coolant pipe.

But in your head it's been blanked off. I would very surprised if the mx doesn't have a temperature gauge on the clocks. I think someone on here has owned an mx before. But by the looks of it you need that sensor.

If you have a look at my build you will see my custom clocks, which have temperature sensors thay screw into the head.

Had a good chat with another lad today who has an mx. Aparently temp gauge and sender never came on the mx. His is exactly the same, so he uses one of these. Strange or what

Cool i ll check out your build cal and have a look!

Calum122 · Guru

Why? That is so dumb! It's such an indicator of imminent failure.

djaniero · DTR Senior Member

Tell me about it man. Doesnt make any sense does it. The digital clock is pants too...no rev counter or temp gauge lol.

Calum122 · Guru

Yeah, the DTRE clock was a bit like that. My new clocks are awesome. Temp, Rev and shift lights :D

djaniero · DTR Senior Member

Sounds just what i need...have you got individual ones or a universal clock?

I hate you Calum!!!!.....My starlet won't be having any cash thrown at it this month now, because I'm on a quest to get the mx back on the road now instead lol.

I need one of thoses displays. With me not having a temp sensor as standard on my bike, how would I get it to work with the display? I could get a temp sensor for an rs, and fit it to my head...but then could I just wire it into that display?

Also what about the rev counter... as I don't have a feature for that on my current display, so how would I wire that in?

Calum122 · Guru

Yeah mate, universal.

Read that, my Bro got one for his yz.

You just buy the speedo and it will come with everything you need.

djaniero · DTR Senior Member

Cheers. did you compare it to this one before you guys bought them?

Calum122 · Guru

As As a matter of fact I did actually. But the vapor stores time which is the deciding factor lol.

But those units are very good and universal. Don't need anything other than what is provided for.

djaniero · DTR Senior Member

hmm. I think I prefer the look of the koso though. Whats the rev tacho like on the vapor....is it as erractic as everyone makes it out to be?

Calum122 · Guru

Never had any problems with the tacho lol. Been using the same one for years now. It's accurate to THE rev lol it tells you the exact rev.

djaniero · DTR Senior Member

Cool. I'll get one ordered in the morning. Got the feeler gauge today, checked the big ends...still within specs :). So good to go to start trhe rebuild!

Calum122 · Guru

It's a worth while purchase if you can't get a temp reading out of your display. I couldn't tell you the amount of times I've pulled over before a seizure because the temperature has spiked. It's a killer indicator.

djaniero · DTR Senior Member

Did you get the one with the built in indicators?

I had a look in their website and there seems to be quite a few universal variants.

Also, will i still need the aprilia temp sensor or just splice into the rad hose with this kit?

Calum122 · Guru

Yeah I just bought their 'universal' one. And bought a 6mm temp sender to put in the cylinder head for a better reading.

And I bought the dash, it's not a requirement, but it's a feature worth having IMO. My brother didn't bother and I don't blame him.

djaniero · DTR Senior Member

I m thinking to get a temp sender and wire off and rs - like in the above pic. The stealth should be able calibrate the readings from this being a universal unit shouldnt it..if its soldered or crimped in?

Calum122 · Guru

I don't know. Just use the Vapor kit stuff. There is no need to go and get an rs sender to use with the vapor when the vapor gives you everything you need.

djaniero · DTR Senior Member

Yeah the rs sensor wire goes into the main loom, so bit of a nightmare to get hold off. The sensor that comes with that vapor kit, looks as if you have to splice it into the rad pipe opposed to having a sensor in the head? I just thought the ones that go directly into the head like the rs one would give a more accurate reading.

Does the vapor have any form of oil warning light also? The stock mx digiclock has a lubrication warning light.

Calum122 · Guru

Yeah you can get an m6 adapter that goes into the head. That's what I have.

I still don't get 'lubrication' light. Oil level light.

The vapor unit is just a universal clock. So what ever you wire into the clock is what you get. If you take the feed from the lubrication light and wire it into the vapor dashboard then yes you can have oil lubrication light.

Calum122 · Guru

After reading the manual, found here: www.manualslib.com/manual/363537/Aprilia-Mx-125-Ed02-2004.html

I think the oil lubrication light is just a maintenance scheduler to tell you to check the lubrication system for faults.

It's a feature built into the odometer that triggers maintance intervals. As said two strokes are fairly high maintenance.

djaniero · DTR Senior Member

Thanks that would make sense :)

Did your bro use the m6 on his yz, or just stick with the sensor that came with the kit?

Does the m6 just screw into the head like the rs one does?

Lastly. I had mega small leak on the rad before I stripped everything down....Everything was tight, no tears in the rubber from what I could see. So unsure as to why it was leaking.

He just spliced the coolant pipe. I did too initially. But I accidently snapled the cable and decided if Inwas going to buy one then I's buy one that slides into the head.

You're talking a few degrees lower. And it's not the actual temperature you're interested. You're interested in a sudden spike that is indicated iminent seizure.

djaniero · DTR Senior Member

Sod it then. I'll stick to the one that comes with the kit. Any ideas on the coolant leak?

Calum122 · Guru

Wouldn't worry anout the coolant leak for now. That will need investigating once its back up and running.

djaniero · DTR Senior Member

Cool.

Ordered pretty much everything now, so fingers crossed they'll get here by saturday and I can start building her back up.

My inlet manifold is cracked slight, but still intact on the inside, so no need to buy one I dont think....Saw one of Ebat from a breakers, but it looked in much worse nick than mine.

Just need to find out what size the bolts are fpr my oil pump - had to round the old ones off to get them out.
