Can I ask, I've started to change the oil & filter on my 2004 fireblade, (late at night and knackered) and it looks like I've taken out what looks like an oil drain plug which sits just above the actual drain plug but not sure what it's for. Any ideas
it might be for the sump plug and crush washer to thread against ,,, I'm going to do an oil change on my 07 soon , should of done it last week but couldn't be arsed
