Why is my coolant boiling and leaking over?
It was hot as hell today in colorado and i noticed that i started leaking green fluid everywhere and that my coolant was boiling. My temp gauge didnt say that i was over heating and I only noticed my fan came one once i got home and was about to turn the bike off. Whats UP? Help?

Several things can cause this. Blockage in one of the internal radiator pipes, The pressure cap is faulty, allowing coolant to get passed what normally a pressurised unit.
The coolant itself may be old & diluted enough, to enable it to boil at a lower temp, (hot day).
Drain the old stuff out, give the radiator a good flush, (good way to tell if there is a blockage) & replace with high grade coolant. If it still happens, then the cap is prime suspect.
On the very rare occasion (sorry to make you worry
) but it can also be a blown head gasket, causing a pressure build up into the radiator,so check you're oil for water coming in & you're coolant for oil getting going the other way.

hey man, I have an issue, I got a CBR 650ra 2020 and ended up in an accident that bent the fork/shocks,rad all the plastics/fenders front/side, one mirror and rad was slightly bent, so i spent 10700 for the dealer to fix it however when I got the bike after repair, the engine sort of overheats and coolant's boiling in the rad as if it isn't circulating, now the dealer has replaced the thermostat 4 freaking times and did not fix the issue, what would be causing this issue, water pump is still new just like the rest of the engine. Please help, this is becoming so damn annoying and i'm stuck with a bike that i can't ride in fears of losing the engine. Thanks in advance.

@r00t3n How about starting a new thread in the 650 section so riders of that model might see the question for help. As it stands, you've replied to threads from 2010 and 2013, which will make most readers have to start at the beginning of the thread with posts from back then. Most readers aren't going to get to your particular issue.
Just offering some helpful advice.
