Oil Temp question
I just cam back from a 5 hr ride, I live in Phx so the last 2 hrs were +90 degrees. I looked at my oil temp using the HD oil level and temp digital dip stick. The reading was 259, I would like to know is this ok. I know a lot of people run in the low 200's but I want to know if running at the 260 mark can and will do any harm to the engine.

Being its an air cooled engine one of the engine operating temperature factors is ambient temperature. A higher ambient air temp will cause the air cooled engine to run a higher temp. This is evident assuming your out on the highway running at highway speeds. Use a good synthetic oil and good filter. Since you live in Phoenix, a oil cooler will bring down the temp some, maybe 20-25degF. I have the HD cooler on my bike and it works good. Other coolers are available like in J&P Cycles.com.

An oil cooler is highly recommended. HD says normal operating temp is 230 for the oil.
From what I've heard those digital dipsticks are notoriously inaccurate...
The HD oil cooler is (I believe) a 6-row cooler. Jagg makes a 10-row for about the same price, and IIRC Jagg used to make HD's coolers. I've been running the Jagg for 3 yrs and couldn't be happier. Between that & XIED's my bike runs much cooler & happier than stock.

I also live in Phoenix and just installed the fairing mounted oil temp gauge with the sender in the oil pan. Running down the road I'm running 200 - 220. Once in town and in stop and go traffic it's running 230 - 250. For Phoenix it hasn't even been hot yet. Not looking forward to riding when its 110+ outside.
