And Airheads didn't have near as many charging issues until they started adding voltmeters. LOL

How do I tell the difference between old & new?



Afternoon Eckhard

A few ways, check motorcycle build date = pre 12/1997 should be external.

Follow oil cooler lines back & should find external oil thermostat assembly.

Easy way= if you have to remove oil line across front of engine to replace alternator belt then assume it has external oil thermostat.

Regardless of ambient temp my '99RT RID oil temp consistently shows
5 bars under normal operation
6 bars stuck in stop start traffic

And only one time 7 bars while riding in the 100th HD parade...Yup won the parade lottery and rode my RT (with a couple tiny HD flags attached and a nice HD T shirt from a Singapore dealership) I changed oil the right after that, not sure if it was needed but it made me feel better!

The moron next to me that was revving the crap out of his new Low Rider the whole way and it was rattling loudly and puffing oil by the end of the parade.


If the good old days were so damn good, why did we bother to invent modern times?

Paul De, Thanks again for the information, sounds like 5 Bars is what to expect on the Temp Gauge... I love the fact that you were in the HD 100th Anniversary Parade! That's awesome, My Wife and I rode in a local Harley Davidson Charity ride last year, when we got to the turn around , they were all thrashed from riding those Harley's , we were still fresh, enjoyed our lunch and whizzed past them all on the freeway headed back Home, Cruise set at 80 on our K1200LT, they were all over reving at 75 !

Cold is 50 or so, hot is 100-104.
Normal is 5 for my 1100RT . That's about, about where the thermostat opens for the oil cooler, ok, maybe 4.5 bars.
In traffic or riding hard, 6.
The only time it gets higher , even to all the way to the top is creeping in traffic, but a short blast of freedom brings it right down.
Change your oil by the book or sooner to feel better, use a quality oil that's correct for the bike.
I use premium gas always, even in "cold" weather.
If you have bugs in the area, Simple Green sprayed on the oil cooler ,let it sit, flush with the water hose to remove they tiny bodies once in a while.
Keep your clutch free play adjusted.

Tri 750, Thanks, sounds like similar riding temps, although it gets much colder, I will ride as long as its 40 or above... second thing I did when I got the Bike was an Oil Change, First was remove the Charcoal Canister... I am using conventional Castrol 20-50... I hear that running Synthetic can cause Oil Seal leaks. I'll keep an eye on the cooler for bugs, can be a problem in the warmer Months for sure...
again, I appreciate the feedback!
