View Full Version : Oil temperature gauge

29th November 2004, 21:39
Just got the Harley oil tank cap with built-in analog oil temp gauge to replace the stock cap on my 2004 1200R. Mine reads about 150 degrees F. with the bike warmed up - just wanted to know what others get for oil temp readings.

Hi John,

Search through the threads and you'll find a lot of discussion about the gage caps. Mine reads about 180 at idle and around 205 at 75 mph. They are not the most accurate, but my contention is that if the gage is consistent, that is, it reads the same when looked at at same conditions, then it's worth while. Example, if it reads, as mine does, always 180 at idle, then I'm happy. If I look at it at idle and its reading 210, then I would get concerned. Just my thoughts on the subject...:chop

Please forgive my manners, I just noted that this is your first post..:welcome :welcome :welcome

Mine reads at 160 at warmed idle, about 195 going down the road. This is with Syn3, and an installed oil cooler w/cover @ 55 f. I imagine this would rise as ambient temps do, but as stated before it is relative to the accuracy of the guage. Best bet is to use it as a baseline to determine where your engine is running, and take it from there.
My best to all..

I have a 98 1200, I warm it to 100 before taking off(about 5 min). After riding for a while it runs about 210-220 in summer(So. Cal) and 190-200 in winter. That is with syn-3 and stock motor except for taxes. When I first got the temp gauge I was obsessed with the running temp, drove me crazy that I was burning up my motor. Pretty much like Darhawk says, see what your average is and only be concerned if it changes drastically.

Mines about 180 at idle, 190-200 running, taxes paid, otherwise stock '02 883, seems the norm.

Albie... You shouldn't list a winter reading unless you live in a place that actually has a winter. My readings here in NY are 210/220 summer and 140/160 winter (@ 30F ).
I too was PARANOID about burning up my motor in hot weather, but now that I run SYNTHETIC OIL, I am much more relaxed about high readings. My only caution in hot weather now is pinging. If it pings I shut it off till it cools.
jpj...Read the threads on syn. oils. THEY REALLY ARE SOME KIND OF DYNOMITE S**T!

Hahahahaah, I remember somebody on the old site said he asked the Counter guy for one and the Counter guy says "Oh, you mean the Worry Sticks"

Mine runs 150 and sometimes gets up to 175, same as the 2 other Sportsters I ride with.

Worry-stick, yeah.
I got one for my '01. It read around 180 when warmed up. I went on a trip, looked down and it was reading over 250! :yikes
After weeks of troubleshooting and hair pulling, (is it the voes, is it oil flow, what is it??), I finally figured out it was the damn thermometer on the dipstick. :cry1
What a pain in the ass. Worry stick, yeah.

I am still waiting to receive mine. I did not order it for the temp gauge but to replace the pop up cap. I had one break on me and one time it came up while I was riding. I notice the smell of buring oil blowing all over my pipes. I hope this will solve that problem. Beside I am watching the road and the ladies, I don't have time to look at the temp gauge. :tour

You can always rig a temp sensor in the oil line and have a digital gauge mounted on your bars.

Mine reads 150 degrees when the bike is warmed up,
. . . at 60 degrees outside temp . . .

Mine ran between 170 and 190 yesterday on a 60 mile ride in 37 degree temps. This is while running Mobil 1 15W/50. When I got home I tested it in a pan of boiling water and it indicated 212 degrees so I guess it is reading correct.

I have one of these on my 04 1200R, it reads around 160 here in Blighty at the moment. I am using the Harley Fully Synthetic oil.
