How To Stop Go Kart Chain From Falling Off Under Load With a Peice of Chain (frame flex?)

This particular kart is swapped with a predator 420 stage 1 with a tq. The simple addition of a chain fixes most if the issues I've been having with the chain falling off. Even after strengthening the frame as I showed ya'll in the video it still flexed. Not nearly as much anymore with the chain! You definitely loose some ride comfort but gain a TON more control and feedback. After all the shock is forced to be compressed downwards. Possibly installing new stiff shocks may help. Not sure as I haven't tested that yet, but the chain trick works! Credit to Cheyenne on Go Kart Buggy and Atv Builders on Facebook for helping me with this solution.
