Hi everyone I am having a problem with my bike. When ever I hit railroad tracks or any medium or large bumps in the road there is a "clink" or "clank" noise that comes from the rear. Any ideas? the turnsignal assembly seems ok as well as any nuts under the rear fender, I have 1500 miles on the bike..... kind of confused

 

the rear suspension is adjustable right? u just need a shock spanner. u could be bottoming out-are u over 250lbs if im not being sooo blunt. u may need to stiffen the suspension a bit-also are ur tires properly inflated? as far as i know that is all i can think of to cause that sound. check around the pipes nuts and bolts wise
