I am not an experienced rider/owner, but I keep my rusted out '87 Dodge Plow truck starting up to plow my driveway every winter and I keep my 725cc Briggs & Stratton V-Twin motor on my tractor running to mow 6 acres. I even watched a mechanic replace a head for me last year after I didn't notice mice had built a nest under the engine cover causing an overheating issue, bending both push rods and destroying the valves. I was annoyed when I realized that I could have done it myself.
