Hi, New to the site here (awsome site). I purchased a 2008 TRX400ex (new) in Mid. October 2010 for my daughter from Performance Honda in Wesley Chapel, Florida. After less than 9 hrs of use it is blowing white smoke (Oil Smell) during engine braking after a long ride. Took it back for them to look at and was told they changed the plug and it needs to be broken in the rest of the way. I've been a mechanic my whole life, and I know that while engine breaking/closed throttle manifold vac. is high and the oil is coming from the valve seals or passed the rings. I'm posting hoping to find other people that might have had this problem. Any help would be great, Thanks.
