Just drained the oil, or should i say tried to drain the oil from my 2000 2.9 sherco. removed the drain plug NOTHING removed the filler plug STILL NOTHING, then while i'am sat there scratching my chin, this thick white goo comes ooozzzing out of the drain hole. I left it overnight to drain,flushed with petrol gave it a good swish about and drain again still lots of white sluge, flush again running clean.Bike new to me,oil been in about 20 hours use.Help
