I did my spark plugs at 12k miles and they were fine. Didn't really need to replace them and I haven't done so since (around 25k now). Plus, I put in the iridium plugs, which are suppose to last longer. Here's my how-to thread and info if your interested: http://www.600cc.org/forum/f88/spark-plugs-18643/
Maintenance on these bikes is a piece of cake. I ride mine like it was stolen and have had to do next to nothing! Love it.....
