Greetings, As title suggests I have a strong smell of petrol in the garage after the bike has been sitting for a while (a few hours / overnight). I have noticed that I get a small amount of fuel coming up through the lock barrel on the fuel tank cap. Which I guess could be normal as it is a place for the tank to breath / vent? (Maybe? Maybe not?) Today, however, I was going for a ride and happened to look down whilst stopped at lights. There was quite a bit of fuel around the flap hinge on the fuel cap - I had been going over a few nasty bumps so I wouldn't be surprised if it was just from the fuel splashing around and trying to get out through the top. Lastly - She (Her name is Zara) has been a bit hard to start for the past week-ish. Will just sit there with the starter trying to kick it over but it just won't go. At first I thought this was due to a bit too much oil - I changed the oil and filter and only added 1.6L of oil (Manual says 1.9L if filter changed) and I was already over the full mark in the sight glass. So, I drained a bit out after a couple of days but the problem remains. So, Are there seals in the fuel tank cap that need special replacing that I can't see? Or, is this a carbie issue where they're just so dirty that they are actually venting fuel to the atmosophere and causing the crap starts?
