put this on face book
it has no place being on fixya site

you need to be very cautious as this culd very easily be mistaken for a loose rod insert...around 2200 rpm hold the idle steady and see if you here a rattle. Then do it again increase slightly then decrease slightly...if you still here it, its possible an insert has came loose from oil run too low or high mileage wear and tare on the crankshaft..if you love it fix it if you dont trade it quickly...GOD bless

see the diagram attached and information and fix it. see the system bypassing fro troubleshooting. God bless you
God bless you

LOVE is a respect for your ride...pamper her...she will reward you:)

here's an easy way to fix your problem. Take nail polish remover, this is not a joke- pour some on a rag and scrub the old yellowish burned film away you will love the difference it makes, they will look like new. You can also get the conversion kit,but nail polish remover is like 2.00 bucks god bless
