I have a KFX 450r I bought new in Jan. 2008. I ride all the time and estimate that I have somewhere in the 100 – 200 hour range on the motor. I have the trinity power kit (Full pipe, programmer, billet intake piece and K&N filter) and I have used Mobile MTX4 10-40 (whatever the high priced mobile 1 motorcycle oil is) since after break in. Very well taken care of but ridden hard. Anyways I am starting to see some blue smoke during the first min. or so after start up when I give the ATV a little throttle in neutral. Is this normal? I am assuming that the motor is starting to wear out but it seems premature to me. My warranty runs out soon and I am considering taking it into the dealer and having them take a look at it and hoping they will rebuild the motor but I assume they will say it is normal wear and tear. Has anybody else seen blue smoke or think this is normal?
