le15otl,
You might need a new crank chainwheel as well, so while you get a new one, flip the current one backwards so the other face of the teeth engage the new chain. Potentially you might need a new freewheel motor sprocket, depending on how bad the wear is on that. I got about 2800 miles out of a BMX chain using first the GNG then the Cyclone before it was at .75% wear. I usually take both chains off the bike for thorough cleanup and measure stretch after 1000 miles, then I do that after ~500 miles. Usually when the chain is at about .5% stretch the time to replace is near... .75% you should seriously consider replace, and anything above 1% stretch its definitively done. Once it gets that bad the entire drivetrain gets chewed up like "no mañana"... Lubing the chain regularly has helped me keep it alive for longer...
