Here's the issue. I have a 95 cbr f3, when i run it i smell coolant coming up near the handle bars. I don't see any leaks or puddles on the ground or smoke. Anyone have an idea what it could be

 

check the radiator cap to see if it holds pressure. the coolant smell may be escaping from there. also, let it run until you have pressure in the system (unless you have access to a pressure checker) then look around at all of the hoses, water pump, radiator, and engine to see if there is a leak. is it low on coolant, overheating, or smell like burned coolant in the exhaust?

+1 to demon, sounds like a pressure-cap popping off early. Double check inside the
fairings for leaks. Sometimes they will prevent a small leak from hitting the ground,
unless you idle in one place for a while.

I noticed the same smell, but I was riding bellow 10 degrees C, thats like 42F I think... I heard when you do this the rad will dump super cold coolant into the engine which is not good.

But as the weather got much warmer the smell went away and never came back- only on the cold days did I notice it. I also have a 95 F3

 

Well i did what you said i pulled the fairings off and let the bike warm up. the smell was there and there are no visible leak. I did notice the smell was coming from the left side and that my radiator fan never turned on. How Hot does it have to be for the fan to kick in?( the temp gauge stayed level in between hot and cold) I also remember that last fall i was riding in cold temps and the next day there was a small puddle of coolant on the ground but nothing after that just the smell.

 

use your nose to trace the scent. did it run long enough to build up pressure in the system? the cap needs to hold pressure, otherwise it will push coolant into the overflow.

 

also no coolant smell in exhaust, hasn't overheated, and i probably could put somemore coolant in. Any certain types?

 

ran it for about 10 min, my cap is on the right side and i didn't smell anything over there, I traced the smell to the top of the motor on the left side

 

some of the hoses on the intake side of the engine contain coolant. look closely at all of those hoses and tighten all the clamps.

 

check for weak/loose hose clamp. this happened on my f3 causing a light leak onto the headers
