new bike foibles

My bike has 5500 kilometres on her now, and boy does she stink of burning, gotten more noticeable recently.
Nothing that i can see thats causing it either
She's going in for a service this week so they can check it out for me.
It's also making a weird kind of fluttering noise thats become much more noticeable in the last month, doesn't really sound like the CCT though, but it is in time with the rpm, especially noticeable when i'm slowing down in the lower rpms, so something else they can have a look at as well!

if its a sweet burning smell check the radiator cap. happened to me.

if its an oily burny smell check the crancase breather
