I recently bought an 07 Strat and love it, but I have a question about the sound of the engine. It has what I would call a knocking sound especially under very light acceleration. I think this is normal as I put a couple hundred miles on a different bike(an 06) and it had the same sound. I dont know if I am decribing the sound correctly, but if any of you can assure me it is normal I would appreciate it. Hope its normal as it is one of the most enjoyable bikes I have ever had. Thanks for any help!
