Default Engine Temp. Question

Does anyone know what the operating temps should be around on the twin cams? What's normal? What would be considered too hot?

Thanks

If you don't have an oil cooler you're runnin too hot.

220-230 on mine with oil cooler
without it ran 230-250+

10-20degrees does make a diff


my temps are after riding for 1/2hour or more.

i have a oil temp gauge and it takes apx 15 miles to reach full temp even at 100 degrees

It's air cooled and you have little control over the temp. I run synthetic oil and enjoy the time riding instead of throwing $$$ into the bike and losing sleep at night worried about my engine melting. Having said that my stock 08 Heritage and the wifes stock 08 Deluxe average between 205 and 230. Stuck in stop and go traffic they'll get up to 250 on the oil temp gauge.

My 09 Ultra during break-in is running about 225 with 90 degree days. Will be adding the oil cooler and syn oils at my 1000 mile service.

Around 250 at the heads is a reasonable operating temp. Some like to run oil coolers, lower afrs to drop it lower. It certainly makes it more comfortable in stop and go traffic and can't hurt. Around 280 you need to start getting concerned and at 300 you need to shut it down and let it cool off. Oil temps? I'm not sure how that compares to head temps.

My 09(96 inch) ranges around 250-265 on hot days. Dealer said I could posibly see 300. If mine gets to around 290-295, I'll shut it down. My 88 inch stayed around 210-230.

Let's see now, if you get a 20 degree temp reduction from synthetic, another 20 degree from an oil cooler, 15 from a Stage 1, and another 20 degrees from a properly tuned fuel mgmt system your oil temp should be about 150. What a bunch of horse feathers! FYI my owner's manual says that 230 is the normal operating temp.

My 95" with Thundermax and Amsoil got not hotter than 225 on a 1600 mile roundtrip from Omaha to Arkansas with a lot of Ozark mountain riding.
