antifreeze over flow

[DaddyRabbit]

Sorry to hear about your Heart Attack. Thats no fun at all. Been there, done that. Bake to the bike. Did the fan come on? I dont see that mentioned in your post. I wouldn't say that coolant overflowing out the overflow bottle is normal, regardless of how long the bike has sat around. Your cooling system is designed to maintain a certain capacity of coolant at all times. If there is an ounce or two every time you ride it or start it up, eventually there won't be enough coolant to keep it cool. I would ride it and make sure the fan is coming on. You can start the bike and let it idle like you are doing a 12 minute tune. The Fan should come on. If it doesn't you need to figure out that issue. Typically its as simple as a temp sender failure. Sometimes a ride is all it takes to keep it cool but I am thinking it is April and the temps are in the 50-60 degree area in NC.

No Rick! I let the bike fan come on, then 12 minutes tune! Then saw the overflow! Took a ride for about a halhf hour and no more overflow!

Well that's good to hear. I would keep an eye on for a few rides.

I am now having some overflow on my 2014 Roadster after riding in stop and go traffic. Fan is kicking in and no issues after a highway blast. New cap perhaps? Any and all advise would be appreciated

Apart house or auto repair shop should have a pressure tester to check the cap just pinch the overflow tube so you don't lose the fluid n the tank

I will get one after work. Hate to lose a week of riding waiting for a new cap. Thanks

If it's just the dribble down the side of the engine block directly under the overflow tank, it's a non-issue.

 

[DaddyRabbit]

if its, 4 to 6 ounces , what is it?

 

[Claviger]

Almost certainly a bad cap, or a not totally tight cap.

 

[Gavin]

Likely about 3 to 4 ounces

3 to 4 ounces is a lot. I agree with Claviger, check that the caps is tight or replace it. Cheap enough to replace.
