You guys are probally gonna kill me but excuss my newbiness in thumperville. I just accuired a yz426f and it runs great. I rode it today for about ten minutes. Took it down the road and then let it idle in the backyard for 2-3 minutes. At this point it began spitting coolant(blue ice) out of the overflow. Is this normal for this to happen? I have heard that you have to keep these bikes moving but this seems very weird. Is there anything that you can do to help this?(Fan or anything) I bought this for trail riding but am not sure it was a good choice if it cant idle without overheating. Help please very frustrated.
