Finally got a photo of the temp gauge on my bike, mind the quality, taken with a cameraphone.. This is after.. 45 min or so on freeway and about 15 min in city traffic, this safe?
also attached is a photo of my bike and my car, guess what gets driven more. ;)

That's still safe. You see that little red portion. That's not safe.
But most needles sit between the thin and thicker line.
That's where my bike sits but when I sit in traffic going no where it can move up to almost where yours is.
Where was the needle on the freeway and where was the needle in traffic?

Needle in traffic is as taken.. Needle on freeway at 60-65 is a hair above the thick/thin. 70 it goes up, but not that much.. I'm personally thinking its safe. (i took that photo after sitting at a light for 6 min, idling.)

That's fine.
If you haven't flushed your system and put new coolant in you should probably do that just as a maintenance things.
There was someone that suggested a cooler coolant but I cant remember what it was.

You didnt mention what the Air temp was, Mine will run up to the same temp zone even on the freeway when outside air temp is above 80F

My D and 650C always run cool but sitting at a light on a hot day the temps always creep up a bit. On the C and I, I always listen for the fan to kick on and the little needle always drops back. Coolant gets changed every other year. As long as it stays outa the red, I sleep well in my bed.

Radiator needs a flush, BAD.
I'll check the 7v. But i can feel the difference in heat off the engine, just so you know. when the temp goes up, so does the temp on my legs. :P

When I talked to Tom this summer while he was going through his heads he said that he spent 2-3 hours cleaning out old solidified coolant.

My GL500 temp runs very similar to Cf2008's. I changed the coolant two months ago when I purchased the bike (coolant looked new but I'd already prepped to change it so I just did) but didn't flush the system. I live in the desert where it's usually 85+ degrees between 8 AM and 8 PM, and can see at least a needle width change between riding in hot temp or sitting versus cooler ambient temps at highway speed. I know my coolant is circulating, but it may not be flowing as efficiently as it could. Is there a good / easy way to check adequate coolant flow?

That doesn't sound excessive for your ambient temps and there's no real way to test the flow.I'd just give the system a flush and check the 7v Regulator as per above links.If the bike were reading in the middle or above under normal air-cooling then I would concern myself.

My bike overheated.. 20 min in stopped and go traffic, got up to the red again, and boy could i feel it.. :/ plastic even got hot, tank was burning hot, fairing was burning hot. 104 degree heat + traffic = a bad idea apparently.. might do an electric fan conversion.

IF your original fan on the bike was working ok then switching to an electric isn't going to help....the only difference between the one on there now and an electric is that the electric will only come on when the bike gets to a certain temp whereas the original one spins all the time.
Since your original fan was spinning (assumed) then a different fan spinning isn't going to solve your problem.
1. your fluid is old and bad
2. the fluid is not circulating hence a clogged radiator OR a bad thermostat. I would flush the whole system good and as well flush the radiator as per several threads discussing the matter here....I would also get a new thermostat just to be safe.
3. if your bike totally overheated then I'd also assume that your gauge is correct and the 7v regulator test will prove to be fine since the gauge told you it was getting HOT !

Engine Ice, Water Wetter, Semi-synthetic oil, all of which can be found at any Cycle Gear store or www.cyclegear.com.
(any semi-synth oil brand that does not have friction modifiers will do, personally, I use Repsol, but Castrol Semi-synth works fine too, and it's a little less expensive).
Your bike WILL run cooler.
Water Wetter makes the coolant much more efficient by eliminating bubbles in the cylinder chamber.
Engine Ice is a non-toxic, silicate free coolant.
Semi-Synthetic oil is also more efficient than standard oil for lubricating engines.

My electric fan doesn't kick on until the needle is about 3/4 of the way thru the thick part. Is that bad?
Lemme tell you, ATGATT while sitting in the 98 degree Alabama sun at a light when the fan kicks on is HOT! Also, Hondaline fairings are surprisingly good at diverting air, so once you get moving, the hot still doesn't blow away very well. At least the fan kicks off.

I believe Honda got lazy at the end-of-the-line with the CX650s and fitted an incorrect switching thermostat as the kludged the electric fan system onto the bikes as they started to come in on all automotive vehicles at that point in history in the early 1980s
If I ever owned a CX650 the 1st modification I would make would be to bypass their switch and use one of my 75 Deg C N/O Rad top mounted switches as per,
http://globalcxglvtwins.hostingdelivered.com/viewtopic.php?f=7&t=209
Both my Fans on my CX500s kick in just on or under the middle mark and cut out just under the nominal mark.
For 99% of the time my cooling system/Temp gauge stays on nominal marks on both my CXs and my cylinder head temps are an even 85 Deg C at my test points on both my CXs when nominal.
If at these specs the fan stayed on too long I would look into enhancing the cooling system maybe with an oil cooler as I think the 650s may run warmer than they should which has been posted many times being a contributory factor to them going through Stators faster and may even be an added cause of their Start Flywheel mechanisms going down faster than the CX500s.

Well, remember, the GL500 has a shaft driven fan, it doesnt move much air in traffic. my legs were burning through my pants. i have to figure this out, i took my car today though.. im running Syntetic 10w-40 right now, fresh oil, perfect level

If you decide to convert to an electric fan Shoreride on here has some of the correct Temp switches that I use and I have some more and can send from the UK if required at a low price e.g $10 inc for two(One as spare) inc postage.
I seriously suggest you address flushing the cooling system and taking the Rad off and doing that as well and checking that the water pump impeller is doing it's job.

Most of the time I like that feature here at 52N and some 1800 or so miles north of Alabama.  The foam back protector in the leather jacket is a bonus too.
