I just bought a new honda cbr 600 2008, Ive been riding for a week now and today when i turned it off after coming home from school, a fan kicked on which i think is a cooling fan, is that normal? How hot do engines usual run at?

 

Your normal running temp should be anyway between 173degrees - 200degrees. Cooling fan kicks on around 215-217, I believe and your bike shouldn't get hotter then 230degrees.

Congrats! on the new bike purchase.

 

My bike in an 07, and it usually runs in the mid 170 degree range. The fan relay is controlled by the ECM, so it is possible for it to run whenever needed.

 

Yea but the problem he had was the fan turned on when the bike turned off.... thats not normal

 

well...in this case he wud need to ellaborate more...bcuz the engine cud hae been shut down "turned off" but the key cud have still beenin on mode...thereby allowing fan to cut on ii believe...?
ii cud b wrong...

 

Exactly!, I did not go into detail because the ignition(sp) could be on still but the engine could be shutdown. Which is completely fine. More details the better.

 

Mine has come on many times after the engine is off.

 

Does he mean off (as in kill switch off, but ignition turned to on) or does he mean he took the key out and the fan still kicked in?

Even if the engine is off, and the ignition is on, the fan will still kick in when needed.

No i took the key out completely and it ran for about 5 minutes until it hit like 210 i think and turned off. But yeah the key was out and off. But i spoke with a tech at a shop and he said it was perfectly normal and that ignition on or off has nothing to do with it so its alllll goood. Thanks for the replies fellas.
