LOL, yea we have hot days with heat/UV warnings. We get great riding weather here, obviously except for the rain.

My main concern was when I drive downtown in stop and go. I noticed the temp gauge on my cbr125 go from very low to halfway (hot)...even other poeple bikes, same thing. SO an air-cooled engine in that situation seemed very scary but I guess not really.

Side Note: Some useful info though, the liquid cooled couldn't cool my bike as quick as the air cooling.....air cooling is optimal....temp gauge just drops after couple mins of riding it thru

The difference is that air cooled bikes have low compression. High compression engines produce a lot of heat. If you sit on a cb750 which is air cooled you notice it's not nearly as roasting as a GXSR which needs the liquid cooling because it's a high strung engine. Also the fact that the GS500 gets such excellent mileage means that it naturally produces less waste heat than a similar sized higher powered liquid cooled bike. More power=more heat. If you're really concerned you can get a small 12 volt fan and wire it to a switch so in stop and go you just flip it on and it blows air past your oil cooler. Even a little air across that oil cooler will cool the bike down sufficiently.

Water cooled bikes also feel hotter because they have a large body of water that is radiating off heat much more effectively than an air cooled engine.

Thanks for the fan idea, might consider doing it...with a manual switch...I have experiences friends who can help to install
