08 700 3300 mi. Have changed the plug one time after fouling on a cold start up in 30* temps at about 1500 mi. Other than that one time it has always started and run great.
09 550 2400 mi. Have never changed the plug. Starts and runs great.
IMO, the key to long plug life is to warm up the engine before giving any heavy throttle and to make sure and have some run time at high RPMS to keep the plug cleaned off. In other words, don't just "putt" around and then shut the motor off especially on a cold engine!!!
Those that have fuel controllers make sure you don't run too rich!!!!!
I do carry spare plugs on the bikes because you never know!!
