Checking the oil.
This bike is rather a pain to check the oil, if you start it and let run for just a few minutes to start to warm up, under 10 minutes, and then check the oil with the dip stick, it may show no oil on the dip stick at all. On mine if I let it warm up for 10 minutes then oil showed up on the dip stick. This is strange and I don't know what is going on with that as you are checking the oil via the dry sump oil tank. Apparently when you first start the bike it sucks the oil from the dry sump oil tank and it takes a bit for the system to return oil to the dry sump take.
This makes it rather a pain in the rear end to check the oil and could have you adding a quart of oil when it really does not need it. This is something I think Yamaha needs to look at.
My advice is to only check the engine oil when it is up to full operating temperature so the oil system has had time to fully circulate the engine oil through the system and back to the dry sump oil tank. Maybe checking the oil at the end of rides would be the best method so that the oil is up to temp and fully circulated through the system.
Also this bike must be stood upright or you will get a bad reading, the dip stick is very short so thinking you can check the oil with the bike on the side stand will not work as the oil will show all the way up the dip stick even if you need to add some oil. Best to just check the oil properly with the bike standing upright.
