I agree with DANR, warm up that engine for a few minutes before you start out, then drive slow for about a mile. That will really help with piston life. Also, another big one is to run slightly rich. (Not super rich!
Your plugs will not last two years, but your pistons will last a very long time. Also, a good quality oil at around a quart per tank of gas and you will ride for years without any engine problems. I'm on year three on the Mach Z I beat the piss out of the motor by riding at 100mph plus and drag racing it all the time! Looks as good as new. Zero motor problems so far.
