If you start her the next day you never get the BAD engine sound like she going to blow-up. This only happen went she sit for 4 or 5 day and you don't start her up. do any of you know what this sound is and why and how can it be fix.

Sounds like it might be a clutch rattle but the fact it only makes the noise intermittently rules that out.
Maybe the starter clutch? Does it sound anything like this Honda DOHC?
