Hi All

My first post here

I have a 1993 daytona 900 which I absolutely love but recently something strange has been going on.

I ve had it for over a year now and when i first got it the temp gauge was normally on the very bottom line and then if i got in traffic it went half way up the gauge before the fan kicked in.

Then all of a sudden it started running with the gauge on the middle line (Near the bottom) which I am told is where it should have always been but when I get in heavy traffic the gauge goes to within about 2mm of the red before the fan kicks in.

I ve changed the coolant, cleaned the radiator of mud and stuff which has made no difference.

I recently took the bike on a 250mile round trip with no problems (Although I didnt hit any traffic) with the gauge staying on the midle line through out.

I should add that the bike doesnt go into the red when im in heavy traffic and as soon as I get out of traffic the temp drops again, just makes me feel uncomfortable seeing a temp gauge that near the red.

Can anyone tell me if this is normal, where the gauge should be or should I be getting worried about it, also is it possible to change when the fan kicks in? say nearer the middle of the gauge

thanks

The temp indication & fan are two completely isolated functions with different sensors.
The fan is controlled by a thermoswitch in the radiator - when the temp exceeds the switch point, it turns on the fan until it cools and resets the switch.
I suspect from your description there is nothing wrong - or different - with your fan switch - the fan will typically not operate until quite close to boiling.
And it appears that situation is unchanged with where it operates, it is more your temp indication that has changed. This could have been down to improperly bled system (assuming your temp sensor itself wasn't replaced) and not indicating normal temperature. That appears to be remedied now as gauge is operating in the 'normal' zone.
I think you're just fine.

Fan ThermoSwitch is item 28
Coolant Temp Sensor is item 17

If your bike was truly overheating, you should notice a lot more heat coming off the engine.

Gibbo, The info I have is fan on at F217 and off at F212.

My '98 T595's fan switchs on at slightly different needle positions on the unmarked temp gauge. Generally it's half way between the second and third hash mark. I'd marked the 'fan on' position on the temp gauge with a felt tipped pen when I first bought the bike while it sat running in the garage. The fan start point can be off by three needle widths either side of the mark on the road.

Usually it runs a couple of needle widths above the second hash mark out of heavy traffic. Reads like your '93 is doing just fine.
