ive got a rattle from my 2006 cbr 600 rr when decelarating in neutral sounds like a rattling exaust but exaust is firm any advice bike only done 3000 miles

 

Have you checked your chain tension? I had the exact same problem with my F4i. I tightened the chain and problem solved.

 

yurpppp +1 to checking the chain for being too loose or rubbing on something. I had a similar problem on my f4i except it turned out that my left rearset had somehow got bent in just enough that the chain would rub against the shifter linkage when i would decelerate. I just unbolted it and put 2 washers behind it and bolted it back on so that it wouldnt rub anymore and i was good to go.

 

thnx guys ill try that its my first 600rr upgraded from a 600f sport
