Cooling fan kicks in at 103 but off at 105?
With the recent heat my bike has been running hot. When it reaches 103 (normally when I get home) the fan kicks in. I've left the ignition on so this happens but if it gets to 105 the fan switches off regardless. This has caused it to reach 107 before beginning to cool.
The main reason this concerns me is that I'm planning to fit full fairing soon and this may cause problems. Q) What is likely to be cutting the fan out at 105? temp gauge fault? Q2) There is a mod to have the fan kick in sub 100, but I can't find the links. Any ideas? Cheers and summer beers, Neil Sv1k 03 |

Re: Cooling fan kicks in at 103 but off at 105?
What year is the bike?
I know that on my K6 is kicks it at 105, and doesn't stop until it gets back down to 100?

Hi Steve,
Its a K3 1000. It has only started with the heat but as I plan the full fairing I'm a little concerned. I know I've read about mod that means the fan kicks in a lot lower. Possibly a resister or after market temp gauge but my search skills are pretty naff. Cheers, Neil |

From reading your post, it sounds like you are stopping the engine so the fan stops, but leaving the ignition on to read the temp?
If so, I'm not surprised. Don't think the fan turns without the engine running on the SV |

If that is the case, then yes the fan does stop as soon as the engine stops running. And it would still increase a few degrees because the coolant temperature fluctuates as it goes through the system. To test it properly, turn it on, leave it to idle up to normal running temperature, and then start revving the engine to get the engine warm enough so that the fan clicks in (keeping it around 6/7k for 5 minutes or so should do the trick).

That is what I'm doing....though stragley the fan will kick in when in that mode. Will leave the engine to run a little longer tonight before switching off.

Im sure it wouldn't take much of a technical know how to put the fan on a manually operated switch rather than the sensor.
