Riding to day I could hear a rhythmic tapping sound. I occurs when I ease off the throttle. I think it is the chain tapping against the plastic chain guard when tension on the chain from accelerating is released.

I pulled over and was able to move the bottom section of the chain up and down between 2 - 2.5 inches. This seems a lot for me but I have read that bikes with a single shock absorber at the back have more play then dual shocks.

I have a 2000 Honda VTR250. Does anyone know if thats an acceptable amount of play and if not, whats the best way to remedy it (new chain)?


The rule of thumb is about 1 to 1.5 inches of slack, so it does sound like yours is too loose. Your bike manual will tell you exactly how to adjust it - there are many different ways, but generally there will be an adjuster screw on each side - make sure you turn them the same amount, and check your wheel is still aligned afterwards!

  • Most bikes have a measurement on the sticker on the swing arm too. Remember different bikes measure it differently, my ducati tells me to measure it on the outside of the chain - i.e. the 1.5 inches should include the thickness of the chain at top and bottom, so really only around .75 of an inch play.
