so this is the deal. i recently got the heads reconditoned on a v twin nv400 and after about 2000km i start smoking heaps and heaps and would hardly go. so i took it back to the mechanic he rang the other day and said the coils stuffed and one of the cylinders is burning too hot and it blew a hole through the piston? had never heard of this ever happening or didnt think it was possible. when the bike crapped out there was oil all in the air box and dripping out the exhausts. originaly i thought there couldve been oil coming in the airbox through a breather pipe from engine. the mechanic seemed a bit rough and i though he couldve put something back to gether rong on the head as he seemed like he was in a hurry. there are breather pipes coming from there and it could cause the engine to smoke if the airbox is full off oil.
when i got the oil back from him i checked the oil and it didnt even show up on the dip stick when cold. it just did when hot and alot of the bolts on the bike came loose so it seems like he is rough and was in a hurry and this makes me suspicious of him.
what i mainly want to know is, is what hes saying someting that can actualy happen? didnt think a hole would be able to be burnt through a piston and the engine temp was normal all the time.
