it blows out blue smoke! Help

[redrider05]

I just rode my 400 today and saw that it started blowing blue
smoke right after it hit top end .I heard that means the rings are
bad or it is running to rich. So anybody who has had this hapen
please give me some advice:confused:

When you have a dark smoke it means it is too rich, but if you have white smoke (or blue??) it is because it's burning oil. Could be a ring or a valve guide is dripping.
Is it new?

no its a 2000 model.I just put in a new piston and rings.But i will
check.to make sure all of it is working Thanks:D

If piston and ring are new that is why it is burn oil. After some hours of use the rings start to seal perfectly.

when you put the new piston and rings in it did you hone the cylinder atleast?:huh
