There is no need to run the gas out of the line when you turn off the petcock. It's not a 2-stroke, and as long as the petcock is "off" you wont spill gas out the overflow in case it tips while it's parked. The oil level in the sight glass is VERY easy to misread.....be sure the bike is perfectly level (which is nearly impossible to do yourself, or also if your assistant has been consuming too many malt barley pops)

At any rate....make sure the bike is level. If you have some doubts, change the oil and filter and add only 3.8 US quarts. (remeber to fill the filter and lube the filter seal) Ride Safe! Scott
