need help with 06 450r

[TITAN450R]

i wish my first post could be a better one but was letting my younger brother ride my 06 450r (just bought from dealer three weeks ago) noticed white smoke coming from the exhaust. if anyone has had this happen or knows the cause please let me know thanks guys.......

Is it a blueish color, or definatley white? Is it constantly smoking or just after start up?
Blueish color means it's burning oil and white smoke means your coolant water is leaking into combustion chamber, which means a bad gasket or worse........a crack. If it is still under warranty , I would take it to the dealer. If it is constant smoke, def take it to a mechanic immediately.

good luck

Was it new or used? Maybe a bad ring seal if you used the Honda method for break in.

If its doing it on start up its more than likely just moisture trapped in the exhaust burning off. If it does it a lot, bring it back to the dealer.
