So I'm installing a 2019 aro 120 kit on my 2014 kx450 and the plastic chain guides are not looking correct. I installed the thin brass spacer behind the engine drive sprocket but the swing arm chain guide doesnt align with the chain. The chain guide has a taller groove that looks like is supost to run down the center of the chain but it is about a 1/4" off to the side of the center of the chain. If I run it like this the chain will eat through the guide and loosen the chain up super fast. Has anyone ran into this issue? Have any suggestions?
