I traded for a 2006 R6 a week ago. I noticed only one fan kicks on. I’ve hit 108°c at the highest temp so far but only 1 fan kicks on. Could this be a fuse issue or do I need to dig deeper?

If your fuse blew neither fan would work. In my opinion you have a wiring issue or a bad fan. If you dont have an owners manual i suggest you get one and start doing some troubleshooting and maybe some of us on here can help you out.

Unplug the connector. Go into diag mode (see service manual linked above) and go to the diag number that tests the fans. Take a voltmeter and see if the wire harness is getting 12V when fans are on. If it is then you know you have a bad fan.

I also just picked up my first 07 R6 this week. I just noticed that the fans don't come on. I hit 196 @ idle.

At what temp should the fans kick on if they work?

Thanks in advance!

I think its like 200 or 205. Check the service manual. I can't remember what it is off the top of my head and my ECU has been flashed so mine come on sooner.

Haven’t had a chance to get into it yet but I know the bike was laid down on the left side and coincidentally, the left fan isn’t working. I’ll be peeling the plastic off after work today and doing a visual. Thanks for the info

Thanks for the help. I dug a little deeper this morning and found my left fan was seized. It broke free and started spinning by hand so hopefully it’ll work after I test it with a 12v direct source.

On the 2008+ models, the OEM fan setting kicks on at 214F and off at around 208F. I flashed mine to kick on at 206F and off at 196F so I wouldn't be roasting whenever I'd decide to ride on a hot day. The temps are really more of a personal preference if you're going lower than stock. I would definitely not recommend raising the temperature to turn the fans on higher than stock.
