Yamalink Install Question

I purchased a Yamalink for my '09 WR250R but am having problems getting it installed.  When I was removing the old link, there was a lot of pressure on the rear bolt and I had to use a hammer to knock it out.  When it finally popped out, the bracket that the rear attaches to (which the shock is mounted on) moved backwards and now the holes don't line up with my new Yamalink.  Any ideas on how to go about fixing this?  Thanks....

Looks like you have the bike supported by the shock mount?  You need to support it from the frame or skid plate under the engine, then move the swingarm up or down until the shock mount and link holes align.

I've currently got it supported by a rear stand that goes under the swingarms, so it sounds like that may be the problem, thanks! I'll figure out another way to get the ass end up in the air and see if that helps. Thanks again....

Thanks again wwguy for the help.  I bought a scissors platform jack and by using it to lift the bike from under the skid plate, the holes lined up perfectly.   Thanks again.....

One more question.  Anyone know what size the bottom nut on the shock is?  It appears to be 25mm but would like to know before I go buy a wrench for it.  Thanks...

Not sure what size it is, but I just used an adjustable wrench on mine. That worked just fine, so if you have one lying around, no need to buy a tool just for that one nut...
