thank you guys for the replies!
when I wrote, I already checked the needle valve and floats. everything seems OK.. I have concluded that it is possible hit mote...
checked the oil level in the engine and found no increase the level I was lucky!
the smell of oil is not checked...
I replaced the air filter, because the former came into disrepair...
well yesterday I rode on my Savage approximately 200 miles away and everything is OK... extraneous noise and damage not.
thanks again!!!
