Can anyone help me with a high temperature reading from my LED dipstick. After my ride last week, approx 75 miles. Air temperature 85 degrees. My dip stick read 308 degrees. Yesterday 75 miles in 80 degree weather the dip stick read 281 degrees. I took it to my local dealer he said that the dip stick was probably the problem. He took the bike out for a 5 mile ride, the dip stick read 240 degrees, he hooked it up to the computer at the same time and it read 230 degree ENGINE TEMP.

Should I be worried, I was thinking about boiling some water and checking the temperature with the LED Dipstick.

The dealer also tell me the 2009 engine cooling system come on at 278 degrees.

Hello Sparky,
Yesterday, 85 degrees, 60 miles, solo rider, highway and local stop and go, 277 degrees on LCD. Pulled dipstick and inserted a thermocouple attached to a calibrated digital thermometer, read 278.5 degrees! Dipstick is fine, it's our too lean, too hot 110 cu in engines thats the problem. This is a factory stock 2009, CVO Ultra Classic. Next week it will no longer be stock, my cool it down, speed it up program begins!

Other temperature readings (surface mounted thermocouples) max temps 45 minute ride, highway and local, normal driving, solo, 85 degree ambient temperature.
Front pipe at oxygen sensor      682.9 degrees
Rear pipe at oxygen sensor       883.0 degrees
Header at middle of cat           1041.0 degrees (ouch!!)

This weekend I had a lot of stop-and-go and idling riding two-up on a 90+ degree day.  I was expecting a frighteningly high oil temp, but twenty seconds after shutting it down it showed 228 degrees.  On the highway the next morning at about 65 degrees ambient it was running 195 degrees.  Stock it would have been at least 30 degrees hotter for both situations.  Get rid of the catalytic converter (radiates heat back to the engine - and you), and put some sort of fuel management system on and you will see lower temps.  I couldn't live with a 270+ degree engine.

OK, Interesting. A little more about my bike:

1) The Cat is gone, replaced by the 2009 non CVO head pipes.

2) Reinharts slip on installed

3) SE Heavy Breather

4) Super tune done also.


OK, now any more ideas? also every once and a while I do get pop on deceleration. Maybe still too lean?

That should have helped greatly.  I get popping on deceleration (will get it re-tuned soon as I am less than impressed with what the dealer that installed the SERT ended up with), so we aren't that different in that respect.  I am at a loss to explain the running temperature difference.

308°???      I forget the magic number but I was thinking it would shut itself down around this temperature.

I have the 09 dipstick temp gauge, Checked it in ice water read 33*. In boiling water I get a fault code but it read 220* , where it should read 212* at sealevel in boiling water. I think these gauges are off some. I would like to install a in dash gauge but so far HD has not come out with one that matches the dash gauges a 100%. You may want to check the engine oil temp with a differant measuring devise. Such as a infared thermometer, ect.    Doc

A couple of weeks ago, we road all day  from OKC back to Texas with ambient temp at 105 def F - running US281 at 70 mph most of the afternoon. Dip stick at 280 - 285 immediately after stopping.

Bike has no cat, SSERT, but also has lower fairings

Most common reading is about 260 on 90 deg days.

fellas fellas fellas, not all led dipsticks are the same, Ive gone through 3 to find one that is accurate. get one of the infrared temp guns and shoot it down into the oil and get reading and compare to led. how i do it is this. get the bike hot, run it up, pull over check the dipstick then pull it out (the bikes dipstick ok) and shoot the laser in the oil. either get a baseline to work with or take it back.
highest readings I get in 90+days is 245 no cat, fullsac 2's, TTS, Big sucker, and lower fairings

Just got my ride back today, I had it in to install a D&D 2 into 1 exhaust. My dealer found a problem, a exhaust valve was not closing, this may have led to the high temp problem. I am not sure what this did but the tech said the spark plug was "white" he thinks now that the valve and the guide (I think thats what he said) is replaced it should help.

Dang,    I'm trying to figure out why the valve wasnt closing.  It's not like there is any adjustment.   He didnt splain why or what he found with the valve?
