Chain Tension

The chain tension on my 2002 Suzuki GSXR keeps loosening up during every event. Used to have a split sprocket so this winter it was replaced with a high quality one piece sprocket. The chain is also of good quality and brand new, as each chain at the start of every year has been.



The car is a Cheetah.



Does anyone have any suggestions on what might be going on?



Below are links to some Cheetahs found online to show the chain tension set up.
