Maybe should have posted this in another thread, but I trust you fellow softtail guys so here goes.

I am running my 06 with Amsoil in all three holes, have a tuned PCIII, pipes, SE A/C kit. My running temp per the dip stick guage today after running about60-70 miles at 90 - 95 degrees was 225. May have gotten close to 230. Mostly all highway riding.

Is this about right for my set up and riding conditions? The reason I ask is b/c I have read some guys running at 200 - 210, but when the temp gets over 90, I can't keep mine below 220. Just want to make sure I'm safe.

 

I have synth in all three holes too. The bike on 90 degree plus days runs around 220 to 230. Im thinking your good.

 

According to the 06 softail owners manual and the service guide....the operating temp is 230*.So you are ok. Mine runs between 225 and 230 an a 90-100* day. Just made a round trip from West Texas to Sturgis,ran in 105*+ temps and never made it to 240.

 

My 2k Fatboy runsclose to220 on real hot days, normally around 214 most of the time tho... I'm thinking your fine at 220!

 

220/230 isn't bad at all, it could be lower, but it isn't bad.
If your concerned about it, you can always add an oil cooler and tune the PCIII to run .1 or so richer.
An oil cooler may not be worth a lot in traffic, but it does help get things to cool down faster and stay cooler once you get moving.
The additives in oil that help your engine live longer be they in Synthetic or Dyno oils are adversly impactedby two things, heat and time. The higher the heat, and the longer it laststhe shorter the lifespan. Any temps over 250 WILL shorten the additives lifespan. Synthetic oils can handle higher temps longer than Dyno oils without tuning into a tar like goo. But the additives placed in it to help your engine live longer are very similar or the same so even synthetic's can'teliminate the overall problem, they just 'postpone' it a bit.

 

I agree with everyone else so far, 220 isnt bad, my bike with its dyno tune in hot weather here in So Cal on the temp dip stick has read 230-250. I really dont put much stock in the temp gage being all that accurate though.

I'maveragingabout 200 and high 210 in hot sunny Florida over 95 degrees. This is with the addition of HD Premium Oil Cooler.

 

I'm not going to worry about it unless I start seeing consistent temps above 230, then I will look into adjsuting my PCIII map. Thanks for all the input guys.
I agree, the bike seems a lot cooler since my dyno tune and synthetic oil, so I'm just gonna ride it.

 

I am planning on getting a Jagg oil cooler for mine. Too hot is bad and oil does some weird chit when it gets too hot. So for me spending a little on an oil cooler to extend the life of my bike is worth the $$$.

 

Just put a HD oil cooler on my 05 Fatboy today. Noticed a 20 degree drop in oil temp based on the oil tank dip stick. Rode around town and checked and than some hyway miles. Pretty much stayed in the 225 range. As this is Tucson in August, the temp at any time is the same.HOT!! B4 the cooler,temp was always around 250.
