I got a timbersled mountain horse kit that came off of a 2013 CRF450r. I am trying to install it on an 09 CRF450r. I know that I will need a new bushing set, but aside from that, it looks like the sprockets do not align. Are the sprockets offset on the kit to accomodate the changes in 2013? Tried calling timbersled but they are closed till monday. Any input would be appreciated. Thanks, Jon.
