Heya, Wondering if anyone here would be able to shed some light on my issue (not a real big one, well, i hope not =P) for my cbr250rr Anyway, I've noticed, after a ride my bike "smells" now i assume this is fairly normal, but apparently it can be quite noticeable. I had a mate follow me ona ride to see. Now, it smells like burning oil, but you can sometimes notice the smell of petrol. It doesn't blow any smoke, well not that i've noticed, even when starting it cold. I've done a google and most of them pointed me to valve stem seals, but most say it is a minor problem, it starts and runs fine, doesnt seem to suck up petrol either (around 220 km? havent pushed it to reserve yet). But, ive noticed taht the oil seems to be so close the the top line once the bike is warm and standing up etc, to the point where it could be over filled. Would this be a possible cause? So really what i'm asking is, Is it bad for the engine? If so, how much would it cost to have it sorted? ta.
