how noisey will my 05 roadking motor get before it desinegrates. the it has 28k miles.sounds like every thing is loose.

 

You won't notice any difference, it'll just leave you stranded on the side of the road

 

First thing to check is cam chain tensioners.

 

My bike is 7 months old with 8k miles and it's sounds like a sewing machine. Reading about the synthetic oil, it's thinner than regular oil, cools faster but has more noise. Personally, I'd rather have regular, hotter oil and a quieter bike.
