ENGINE SMOKE

[300EXRACER]

i just bought my 1997 honda trx300ex yesterday and today i was messing around with it. I saw that the engine was letting alot of smoke out? i think it was from where the exhaust goes into the engine head but i dont know? does anyone know what i should do?

loose exhaust header?

iv heard of people spraying ther bike down with wd40 if u got it on ur header, it would smoke... lol

nah i had checked the bolts, they were tight but my brother said that maybe theres a bad seal or gasket? well the guy i bought from may hav got chemicals on it from puting shine'r on the fenders and tires but ive had it running and i would think it wud stop by now?

What kind of smoke is it? Oil buring smoke or white greyish smoke? Does it come out of the end of the exhaust? Could be bad valve seals.
