Also, I have a question about the direct coupler. I swapped the 37T gear from my one-way that came with the v2 kit (and upgrade pack) and it seems like the front belt is extremely loose. No matter where I put the setting on the bearing housing to tighten the belt, it was very very loose. Did I do something wrong? Am I using the wrong gear?
