I have a 02 cbr f4i when traveling its at a cool 170-180 degrees but if i stop at light it takes maybe a minute or two and its skyrockets up around 200-215 range i hear fan kicking in but it still goes up is this somthing i should be worried about

 

Sounds normal to me. The fan turns on at a preset temperature. When you're not moving, the temp increases due to lack of airflow.

 

my sv650s runs about 180-190 when moving and when stoped hits about 220 then the fans kick on.

 

218 my fans come on. On very hot days its hit 226. If I know I'm going to be stopped for a long time (just barely caught a red-light) I'll just shut the bike off. I dont know what the boiling point of anti-freeze is, and with water at 212 I dont want to take a chance.

Edit : I just did a quick google and got a rough number of 265-276 degrees for coolant to boil....I still dont like it getting that high though. Also if you look at your bikes radiator and look at how tiny the fan is you'll undertand why the fan doesnt really lower the temp any if at all.

about the same here, its normal.if (someone please give a 2nd opinion on this good or bad) your really worried about it you could start your bike up and let it heat up til you see the overflow valve kick in. if you hit 230 or so without anything happening then kill the test early and you'll know you bike is more then safe up at that temp. i cant see why there would be any problems with letting an engine run up to 230F and again someone give their .02 on this.

 

NORMAL

 

You can change the coolant to have less anti-freeze and it'll help it from getting as hot. Anti-freeze isn't anti-hot. My stock 12R, and my high compression big bore 12R both would get hot at idle in traffic, fan would come on, gauge would peg out. Switched to engine ice, it helped alot. Then went to distilled water and water wetter, and it never happened again.

the good advice but the temps hes talking about are normal theres really no need for him to do anything.

But distilled + water wetter = money

 

No real "need" for it, but if it can stay cooler on the cheap, why not ?

$1 for a jug of distilled water from wal-mart, and what, $5 or $6 for a bottle of water wetter ?

 

if its not broke dont fix it..its running at spec

maybe you should write honda and tell them theyre using the wrong kind of coolant

 

That's about normal. Mine even climbed to 210-ish riding behind a semi on the highway. I was 25-30 feet behind, but still cut off enough air. It was hot out.

The factory is going to put something in it that will work in all temperature ranges, it might not be the best for any ONE setting as it's a compromise. Two bikes assembled at the factory side by side, one might go to Alaska, the other to Phoenix. Both with the same coolant.

In my letter to Honda I should also tell them that they're putting the wrong fork springs and rear shocks on the 600 and 1000RR, as neither one has enough adjustment range for my body weight and riding style. I should send copies to all the other major motorcycle manufacturers as well.

 

My owners manual (SV650S) says dont run the engine at over 248. Below that, your cool. no pun intended.
