My yamaha thundercat (yzf 600 r) if ridden at slow speeds then left to idle heats up until around 103 degrees centigrade when the fan kicks in.
The temperature then stays around 100. Then if i get some clear road and ride it faster than 30 the engine cools down to around 80 and stays there till its slow or stationary again.
All coolants & lubricants are at the correrct leves..
Is this normal, or do i have a problem (i havent had the bike long)?
Many thanks

that doesnt seem too out of the ordinary. If you want peace of mind you could get a new fan switch that will kick the fan on at a lower temp or install a manual switch to activate the fan or possibly a thermostat that will open at lower temps.
As suggested, you may want to flush your cooling system and possibly use an alternative to antifreeze.
Engine Ice and Water Wetter are both great options and will help your bike run noticeably cooler. I ride a ZX7R and my cooling system is nothing but Water Wetter and Water (50/50 mix) and mine will hardly ever move above half way on the temp gauge (no digital read out for temp) unless i am sitting in stand still traffic on +90 degree (farenheit) days

What year is your YZF? This is somewhat of a problem with the older FZRs and YZFs. There is something out there called "Ice" that is supposed to be a good coolant to use. Expensive, but supposedly it works pretty well. My FZR wants to overheat all the time if I'm doing a lot of slow city riding and it's warm out (80+ degrees).
You may want to try flushing the coolant system. Drain it and run some water through it for awhile, drain that out then add your coolant back in. City riding is rough on these bikes.
If you want to send me an email through my profile page. I belong to a good FZR/YZF board that specializes in the older bikes. If it's a newer YZF we may not be of much help, but could at least offer a few more ideas. If it's an older one (like pre-97) you should be able to find some good info.
