The post keeps sliding on the neck of the frame. The first time I kind of just put it on there not knowing there was a certain way of doing it. It slipped... of course. The second time I actually installed it according to the GPR's instructions online. I thought I did it right. Well, I put the damper on the highest setting and jerked the handle bars, and it slipped right off. Is there something I'm missing? I'm starting to question how strong this set up is...especially in race situations. Does anyone weld these posts to the frame? I'm lost... BTW, it is a 2006 YZ450F. Thanks in advance.
