I have just about completed the mods on my 2012 Harley Heritage Softail Classic. I was hoping to cool the bike down from the lean stock setup. I installed the following:

1) a FL-XIED-10 fuel enricher.
2) a K & N high flow filter (same shape as stock)
3) a Rush 3" slash cut slip-on exhaust with 1 3/4 inch baffles
4) a Vance and Hines FuelPak 3 fuel management device - I flashed the map for 3" V&H slip-ons with standard baffle (the closest fit I could find for my exhaust).

The V&H FP3 has a sensor function that let's you view various data, including engine temp. Here is what I got at 93 F outdoor temperature on a summer day.

260-265 F engine temp at 70 mph
386 F after riding for 20 minutes and letting the bike idle for 15 minutes

The engine oil temp (measured with a candy thermometer in the oil filler neck) after turning the bike off was 225 F.

Do these temps seem about right or are they excessive?

Thanks,
Wayne

Oil temps is good.

Engine temps are deceiving, because unless the engine is running, at full temps, with air moving over the cylinder, it's never consistent. This is the caveat with air cooled bikes and inconsistent temps, which is why it's so hard to get them through emission requirement testing. Despite, Emissions doesn't test idle and WOT.

As well, temps have to be taken as close to the spark plug hole as possible.

Oil temps are a good indicator.

.
What your saying is emission testing is only at a cruise RPM or did I miss something ? :what?

Calif. vehicle testing is at hot idle and unloaded cruise RPM.
