operating temperature
When its cold out (low 40F) my temp gauge never goes above 1/4 scale which is the first tick on the gauge. But when its hot out (105F) my gauge will go just a hair past 1/2 scale. I'm surprised that there would be a difference in operating temperatures since the engine is water cooled and I believe the thermostat, in theory, should keep the engine at the same temperature regardless of ambient air temperature.
Do you have the same experience?

Re: operating temperature
my temp guage (LCD temp readout on '02 and later models) varies with outside temp and riding speeds from 170 to 200+ The SH radiators don't do the best job at lower speeds so I wouldn't worry much about it. Once the water gets hot the thermostat stays open until it cools below 170 degrees but if the radiators don't dissipate the heat quickly enough the temp will rise above 170.

During this last summer I added that WatterWetter stuff from Red Line and my engine temps rarely ever get close to the half way mark on my analog gauge. Don't know exactly what the engine temp. is but I do know that the stuff works great.

Temp
I've got a new '05 with <500 miles. It's "damn hot" here in MS right now. I notice my temperature going up around 220 F. I know the engine is tight, but it seems mighty high to me. The manual cautions 251 F (122 C) as overheated.

My 05 with 3500 miles has not gone over 218 degrees this summer. That'd be in traffic and shortly before hitting the shade and "cooling speed". Which is completely different than "ludicrous speed;" that'll send you to plaid.
