I had asked this on an earlier thread but I thaught I'd start a new one to help tackle my problem!!
My bike has been starting to run hot in traffic for about 4 months now. It's fine on the open road - nice and constant temp. It's just when the airflow through the rad is slow that the temp starts to climb.
Now I know overheating can be sign that the head gasket is on it's way out, it's just that I must have done 2000 miles with it like this! Surely I would have developed some other symptoms by now if the gasket was knackered. There's no sign of any water in the oil, no steam or smoke from the exhaust, and the engine sounds perfectly normal and pulls cleanly up to the rev limiter.
Any suggestions?

have you got any antifreeze in your coolant? maybe the coolant needs draining and flushing the system and refreshing with new coolant mixture?

I have heard of people jetwashing them with no problems?

I had the same symptoms (or lack of them ) when my head gasket went.
I probably did more than 2000 miles without any other signs than the overheating at slower speeds!
Gotta be worth cleaning out your rad, but even one with about 30% efficiency should really be able to keep the bike cool...
Your fuelling can also affect the cooling - think if you're running too lean it will overheat (but could be too rich - i forget now lol).

Flushed it through with some rad cleaning fluid, rinsed it a couple of times and then filled with 50:50 anitfreeze/water - so far has been behaving very sweetly. As soon as the the water temp creeps above halfway, the fan kicks in and very quickly brings the temp back down and then switches off again (when stationary and given plenty of blips on the throttle).
Fingers crossed job done I hope!
Thanks for your help.
As far as fueling goes, I have a K&N airfilter with std pipes and can. I did use a micron can previously which on the dyno ran a bit lean above 12k. I took it off after getting busted for speeding (102 in a 60 - ouch!) when the copper said he heard me coming 2 miles away!!!

ive had the same problem. i often clean the rad and oil cooler, drained the system and replaced the thermostat. it made some difference but the thing you have to remember is that it is a sports bike its not been developed to ride in traffic; but it can help if you wire in a overide switch to the cooling fan so its on constantly when your sittin in traffic and have it running as it should all other times;;
i did it works well. just watch that the battry doasnt die on you.
