Default 2002 yz125 radiator fluid question

hey everyone so i have a question recently just rebuilt the top end on my bike got it all back together. the bike startd up in 3 kicks i have some carb issues but ill save that for another post. so the next day i went out to the garage to see a puddle of radiator fluid and noticed it was coming from one of the carb hoses. ive read a few places it could be one of the gaskets that are bad or didnt seat right?? so any advice where to start? thanks guys

Most likely a bad head gasket. You can do a leak test to be sure.

If its coming from the carb, it's fuel not fluid. Double check what it is, and from where it is coming.

I doubt that coolant is coming from a carb hose. It is possible, and if it really is, the crankcase and pipe will be full of coolant too. Like stated above, double check the "what" and "where from".

Yep. your assembly must be clean if it isn't dripping black. What are you using for coolant?

Usually that breather tube lets out excess oil
