Operating temperature

Just a quick question. This morning I started my bike and just let in run for about fifteen minutes. The temp climbed to almost 215 and I didn't hear the fans kick on. I hoped on the bike took it around the block and the temp came down to 185.
My first question is at what temp are the fans supposed to kick in?

Also what temp are u guys getting when just idling for an extended time?

Thanks Chris. My bike is an 2004 and has fans on both radiators.

Coolant looks great and is full.

Sounds ok. Your stock thermostat should open and circulate coolant once the bike hits about 175 -180. But the fan doesn't kick on till 215 -220 on my bike. Then it shuts of once the bike has hit ~200. In the summer time my tempuratures are arond 90 -100 degrees outside. My bike consistantly runs around 200 -220 when it's that hot. That's fine. If you start seeing temps in excess of 230, then I'd start worrying why.

I said fan, cause SP1's only have 1 fan. Yours should have two.

RC51 run hotter than most bikes...Engine Ice has brought my temps down by 10 degrees easily.
