2013--Erratic/Random Coolant Temp Readout--Problem?

[AKjitsu]

My 2013 does the same thing. At steady state highway cruise the temp fluctuates up and down by 40 deg. F over the course of 90 seconds. I'm gonna wait until the more techno-types figure out the problem.

I have seen mine anywhere from 140ish to up over 210, didn't freak me out as i drive a 50 year Ford so i am used to it....

Thanks. Not doubting your observations, but--to be sure I'm clear, you are seeing large jumps up and down every few seconds?. Not doubting what I have is "normal" and a "feature", but it does appear unique to this bike--my FZ1 doesn't do it. Man I feel like an idiot if this is the first I'm noticing (should keep eyes on road), but I would swear I've glanced at the thing enough in the past that I would have noticed it before.....

You seeing these large swings as you ride?

To be honest I have never studied it that close while riding.......I will try and look at it later this am.

Fluctuating "frequently" by 50 degrees is "totally normal"?

yes. that is all.

Super-Duper POS Gen IIIs!!!
That just ain't fucking right!

So, for the great Gen IIIs, we have.............

- A POS cruise control limited to 'retarded level'.

- Missing swingarm mud flaps.

- Exhaust guard on one side and not the other. WTF????

- And now freaky possessed temp gauges.

Did I miss anything?

I wonder what will be next?

Skooter, it gets WORSE!! I put my air gauge on my rear tire the other day, and GASP! it showed 1.5 lbs less than the week before!!! I had to actually put air in it. I plan on contacting Yamaha and seeing if my warranty will cover it.

Lord, hope everyone knows the tire pressure comment was a joke..... Back to our regularly scheduled Coolant Temp question por favor.....

Thanks. Would *love* to know your first-bought-ever-in-America unit does it too....

Thanks. I'm assuming you mean up and down randomness as I described, with numbers like I posted. If so, and if Fairlaner's and the others' too, it ain't just mine......

RELAX, think about it, the differences in readings you see are lower than the true temps. It appears that the top-high numbers are accurate (no doupt in my mind) so one knows that the engine temps don't go from i.e. 190 deg to 140 deg in a fraction of a second. So what's the big friggen deal??

 

[Geezer]

Most vehicles do not have analog temperature displays, or oil pressure gauges either. Most are either idiot lights or stepped incremental displays like the bars on the Gen 1 and Gen 2 FJR where each increment covers a range of values. I guess if all of our vehicles had accurate analog displays then we would get accustomed to the variations and know what was normal for each vehicle, but most people only want to know when something is wrong and needs attention.

Not as stressed as my persistent posts would imply, but guess I'm NOT sure I can trust the readings on the display to tell me if something is wrong. What am I supposed to do on a 230 mile jaunt between gas stops--watch the readout constantly in *case* I see 230, 240, "Hi" or other indication of overheating? No, I'd rather the display algorithym do some sampling and averaging as on my other 3 yamahas with numeric coolant temp display and give me a relatively constant read that I can monitor. Again, I've only got 1K on this first FJR of mine and really thought I'd seen it be constant before but could be mistaking it for my current FZ1 or recent FZ6s.

If this is investigated and deemed normal I'll live with it because as I noted, at slower speeds and stopped the readout is constant and I can monitor it then. For now my misery is looking for some company in other folks with this erratic readout over such a range of temps.....

Thanks. Under about 40mph for sure, the readout is constant--changing much less often such as at stop lights (increasing) or accelerating away from stops (decreasing). It will stay at 168 for a long time at 40mph. Why at lower speeds and not highway speeds?

Pseudo-Fed, dont stress, you will be warned if overheated by a warning on your dash. You dont need to "monitor" the c.temp at all. Put that data field on your least used screen.

 

[RadioHowie]

Why not just R&R the coolant system with waterless coolant and quit stressing about it overheating?

https://www.evanscooling.com/

Boiling point about 375 degrees...you'll never have to worry about the bike overheating because your coolant sucks, and a good, hot day and ssslllooowww traffic won't have your bike puking superheated water/glycol mix all over your legs.

Ooooh. I like. But I'd also have to wear the denim shirts Jay is always in when not on camera.....

Oh come on and admit it...you're too cheap to buy a $40 gallon of waterless coolant to put in your $16,000 motorcycle!

it has NOTHING to do with your fashion choices.

$40 I have. Nerve to be the first one to do it, I don't have....

 

[SkooterG]

I declare the digital coolant temperature value readout EVIL, nothing good is going to come of this

I just couldn't wait for Friday for this one.

Which is why I mentioned in it in my '13 review. 'Newer' and 'more detail' is not always 'better'.

You wouldn't be the first. Been running "water-less" for 3.5 years now.

It's really interesting...since the boiling point is 375 degrees, and the coolant NEVER gets that hot, therefore not hot enough to boil, the cooling system is NOT under pressure! Come off a 2 hour run in the middle of 100 degree summer temps, pop the rad-cap with NO fear. No pressure to spew boiling coolant all over the place! Oh...it's safe down to about -40 degrees, too!

Seriously? Cool (no pun intended). Will have to consider it.

You're a fart smeller. I know you can figure it out.
