Pump gas

Mechanic Monday. Tip of the week.
If you use premium pump gas in your motocross bike.
Try this tip.
When we get gas for our bikes at the pump we typically buy very small amounts. 2 to 4 gallons at a time seems common. With that thought the person who bought gas before you likely bought a lower grade of gas. That lower grade gas is still in the pump hose and plumbing all the way to the switching valve. That amount could be more then half a liter which will dilute the small amount of premium you are putting in your bike's gas can. So this weeks tip is to put a gallon or so in your truck first then fill your gas can with the good stuff. (sorry diesel guys no tip here for you unless you have a separate can for your lawnmower.
