Mine usually doesn't get over 225 and that's in the summer. When was the last time you flushed your radiator and changed coolant?

check the level of coolant you have. whens the last time you replaced it? I just flushed my coolant, knows how longs it been like that but it made a very good difference in keeping it cooler. I used water wetter. still have some left too.. maybe could help you out. PM me if you want your bike shouldnt be going over 220 often at all. at lights, yes the temp will go up but shouldnt be going 230+ youre going to damage something man, your bike will explode into confetti

Man that's cooking like said ^^^ mine doesn't get much above 225 in the summer heat red light to red light. Change and flush your system out. If i were you i would run it with distilled water and water wetter when you fill it back up. If that don't do the trick i would check the radiator cap cause if its not keeping the system under pressure then it will cause it to boil, thats why there is a spring and thick seal under it. The next thing i would recommend is to replace the thermostat just cause really all of those are fairly cheap parts. Shouldn't let it get near or over 240 cause thats when your gonna start doing some real damage. Warpage and such. Good luck

might be your radiator cap, The pounds change the pressure/boiling point of the coolant so its very important to have the right one.

EEEK anything above 228 and your lil honda is cooking herself, I agree with others. Flush the radiator and coolant and check to make sure the cap is working correctly

Hottest I ever saw on my old 600rr was around 231 in the middle of summer, stuck in rush hour traffic.

What coolant did you use? Did you bleed the system thoroughly?

If coolant is topped off than make sure there are no air pockets and that the fans are turning on when needed, in this weather there is no reason to see over 230 even in traffic.

My CBRs would never go over 222. Fan kicks on at 220.

My ZX10 used to sit closer to 130 on hot days. I spoke to Kaw, and they said that was fine. Start worrying around 245.

I think it is the same for VFR too.

I had the coolant replaced with engine ice and the temps still climb up to 220(although vfr's tend to run a little hot), but I noticed that it stays in the lower temp ranges when moving by atleast 10 FH after changing to engine ice.

use royal purple purple ice or engine ice if you really flushed it and good there is no reason for those temps. the purpose of a thermostat is to warm an engine up then it opens to allow coolant into the engine. If it doesnt open it has failed. idling too high will cause over heating also

F...I hope my bike doesn't run that hot in the summer. That can't be good for it and has to be hot as on your legs?
