Hey guys

so got my bike on the road last week for the first time and it road real well. I let it sit for a few days and after about 10 min. of idling, it started to overheat. Now I dont have a over flow tank for the radiator (dont know if i really need it?) but it has been leaking some fluid after I flushed the radiator and put new fluid in. I assumed it supposed to leak a little after topping it off. But now after about 10 minutes of idling, steam starts to shoot out of the over flow house. I took a video but dont really know how to attach it or I would but its pretty simple to understand what the issue is. I just ordered a new thermostat so hopefully that will fix it.

Thanks guys

 

Why don't you have an overflow tank?

 

I had to mount my battery close to where the tank would go because I have an undertail exhaust. Do I really need one?

 

When the bike heats up, the coolant expands and overflows into the tank.
After the bike cools down, that excess is drawn back into the main system.
Without the over-flow tank, every time you ride a little coolant is lost.

This will lead to lower and lower coolant levels till there isn't enough to do the job...
at which point the bike will seriously overheat, leading to engine damage.

This totally ignores the other point to the over-flow tank.
Coolant is generally considered a toxic/environmental hazard.
You are also contributing to pollution of the environment, with all of that dribbling.

Finally, the puddle that collects wherever you park the hot bike...it can poison any dog/cat that happens upon it.
Glycol has a sweetish flavor that is attractive and it takes less than a tablespoon to kill a 50-60 pound dog.

So...yes...you need the over-flow tank.
