i just got mine back from the shop. i thought that they were going to fix it's smoking problem but they didn't. what makes a 4 stroke engine smoke like crazy?
valves?
valves?
im pretty sure its from oil either leaking past seals and burning or from valves sticking open a little and letting oil past.
or could be oil sepping past the rings . what did they supposedly fix???
A light tapping would be valves, this could also be causing your smoking problem if it isn't very heavy smoke. Also I would not go to that shop anymore, I would take it somewhere else, not to often have I seen anything smoke when the oil was low, and if it was still doing it after it was there he must not have put enough oil in, haha. I alwasy though blue smoke was anti-freeze/coolant, but it has a sweet smell to it.
