I have a problem all of a sudden with my bike. It has only happened twice. Once while starting off and once while at a stop light. The first time it happened I went to start and it almost skipped for a brief second then went no problems. Then at the stoplight I revved it a little and I hard it skip for a brief second. Any ideas. I bought it a month ago used.

 

You might want to check/replace plugs. May just be a plug wire not on good. Other than that dunno. I can say that my 06 runs much better with 93octane than it did with 89.
