engine sputtering

I noticed when I open my CBX up to about 140KMS, it seems to run great, but when I drop down to about 100KMS and stay there for a period of time the engine seems to sputter a bit. I wonder if among other things this could be spark plugs wearing. I know they are pretty old and I am going to replace them this weekend? Could this be a possible cause?
Thanks

Spark plugs normally break down on higher loadings but a new set of plugs can't hurt..... although I don't think that's your problem Duane. Sputtering ?, could you explain a bit more.....
