Well I ll try and keep this short, while changing the axles on my conquest when I was done and in the air I ran it and noticed that the chains on left rear and left 2 nd from rear are loose on top onoy fiddle string tight on the bottom. I ran it in reverse and it straighten right out perfect tension top and bottom of chains. Took of jack stands and test ran approx 1 mile and loaded right back up left rear chain tight on bottom loose on top that its dragging on the frame . HELP. I have a set of the Adair 18 inch tracks on it and all the chains are tsubaki approx 20 hours on every link in the tub. Is there anything I'm missing??? Almost seems like it s loaded up like no slippage between tire and track on the left side. Is this possible?????
