Hey everyone.  Im sorry if this may be a double post but im kinda rushed and dont have time to search through everythgin to find out.
I was riding my gs to work last night(about to ride it home)and i noticed somethign rather strange happening in the 6500-8000 rpm range.  It seemed a little parched for fuel.  Like it was hesitating and it would drop 250 or so rpms rhytmically.  Then that was accompanied by a slight backfire soundign noise while at those specified rpms.  nothign loud and alarming, just odd.  Help please.
Thanks.
