Hi everybody, I got a 2008 CRF450r. I was riding it one day, and steam started pouring out of the radiator overfill tube. I'm not sure if its just overheated or what. Please help me! Thank you!
Other 2008 crf450r, Steam Coming out of Radiator Overfill Tube?
Most bikes will puke a little fluid also, you might be low.
Possible that the pressure cap has gotten weak also. If you can't test it, just get a new one.
Check your fluid level and your good.

Thank you guys all so much, I wasn't sure if the pistons were bad or what.
I was running it pretty hard, so I'd think it is probably the cap, just like you guys said.
Thank you, I think that sounds right.Imo, sounds totally normal.
When the operating pressures get over the cap's rating, it is INTENDED to leak out the hose to protect the rest of the system.
Never met a watercooled 4T that didn't pee a little when getting a workout in the slow tight stuff.

Hey Andy! 
How's the weather where you are mate? Getting cold there too I'll bet, 
You luck mofo, your parts dude sourced you a whole KX around your cap? kinda wondering if I come to your counterman with just the spare cap that I still have from my cr, you reckon he might be able to match me up a whole new cr?
