200x question

[110rider]

well i got the 300 x running and now when i get on the throttle hard it spits and sputters. could this be from a little moisture in the carb or a head gasket i did notice a like smoke when i start it coming out the left side of the head towards where the top head gasket is

well sounds like a blown head gasket- replace it - and LOCK TIGHT IT- red lock tight is the best for that- good luck
