Today I started up my 99 F4 and left it run about half hour while I did some things in the garage. I did this periodicaly throughout the winter. just to run my bike.
this time when I went to check it it was steaming and antifreeze was shooting out of the bottom of the bike. I quickly turned it off. let it cool . Did anyone ever have this happen ?and what could be wrong ? I think the antifreeze was comming out the overflow but I am not sure.

 

Why the hell are you letting your bike run for 30 minutes without it moving? Your forcing it to overheat doing that.

 

it is 35 degrees out here . and it never overheated before .but when is the electric fan set to kick on?

 

not till it gets real hot. Unless your gona ride it dont even start your bike.
