Hi guys, I have a CBR 125r (i know, take it easy) and i have noticed lately that the bike's exhaust smells a little like fuel. Today when i dropped the oil in the bike it also smelt a little odd, (Can't decide if it is a fuel or just used oil smell), anyway, my question is, could this problem be fuel related? i have been using BP premium 98 exclusively for the last 1000km's. Is the fuel not being burnt and this causing the smell? Cheers in advance.
