Question about 1989 Honda CBR 600 F(1)K
Hey all...wondering if any1 can lend some help for my 99 f4 (lack of) cooling dilemma the weather has been on the cool side (around 40-50 degrees F) so it hasn''''t been a big issue one day I noticed my temp guage was climbing above the halfway mark. when I rode on the highway, the needle sits back at the normal position (right under the halfway mark) riding in locals and the stop and go, the needle climbs back up again. I got back home to check the coolant and it was low. Filled it with the 50/50 mix and thought that was it. Problem remained and later realized the fan wasn''''t working. I would be at a stop light on the bike and when the needle passes the halfway mark, it would sputter at idle and sometimes stall. (starts right back up tho) Checked the fuse when I got home and it was still good. so question is, any1 have an idea as to what caused the fan to stop working and suggestions to fix it and whether the bike stalling at the red light has anything to do with the overheat issue?? appreciate all the help, thanks!
Ast the halfway mark isnt overheating. Any bike will rapidly increase in temp when stopped or moving slow. the fan will not kick on until the bike reaches around 220 deg. Im not sure how that relates to your gauge as Im assuming you have just a C and H with a few lines between., but Im sure its near the upper range of the gauge. I would think your bike isnt hot enough for the fan to kick on. I would let the bike get a little hotter and see. If the fan hasnt kicked on when the needle reaches the upper portion of the gauge, take it for a quick spin to cool it off, dont just shut it off as that will actually create hot spots within the motor, and then consider either the fan is faulty, or the relay. You can pull the fan and test it with a 12 volt battery. One hot, one ground. If it works, it must be the relay. I doubt the stall has anything to do with the bike running warmer, unless it is truely overheating and you have antifreeze pouring out of it, then it might be. You might just be in need of a good carb cleaning.
