I just purchased a 2001GS 1150, riding home in traffic it heats up to just below the red. It was just 100% gone thru at the shop, is it normal to heat up like this ?

Welcome to the forum! I did some quick searching and found at least one past thread:

Certainly, riding slow in rush hour traffic is going to make the temps rise in the bike. Hopefully others with a similar bike will drop in to the thread with some personal experience.

Yes, it is "normal"
You do not mention what your ambient was but you should not be going past 7 bars on the RID
Normal riding should be at 5 bars.

I have found

that running synthetic or semi-synthetic oil makes mine run a bit cooler...

Question: From what source does the temp gauge draw its input? Is it oil temp? Spark plug temp ring? Engine block sensor?

Inquiring minds want to know.

How fast were you riding? Was it stop and go traffic?

It is oil temperature,

Oilhead motorcycles depend on air flow through the oil cooler for cooling. Stop and go traffic may prevent sufficient air flow for adequate cooling, even to the point of actual overheating. Sometimes all you can do is find a way to get out of traffic and shut the engine down to allow it to cool.

Seven bars isn't overheated yet but it is getting close.

I am curious as to how we you able to determine this? Did you replace the stock temperature sensor with an accurate thermometer to measure the oil temperature?
