Can you guys post some pics of this install.

My understanding is that you grind a little off both top and bottom eyes.

Then u pop the sleave out of the top and use stock bolts. And washers invade you trimed it too much.

Then for the bottom you use ken oconner bushings to shrink the size down to blaster size.

Does this sound right?????????,

To my knowledge, it has the same install as the 400ex. You just have a rezzie to deal with. Ken's bushings go in the top mount, not the bottom. Somebody mentioned that there is an additional sleeve in the top shock mount?....like instead of the one there is in the 400ex and 450R shock, they removed the 1st one of 2 in the 250R shock and the stock bolt worked fine supposedly then. I'd investigate it more though, because if that works, you wouldn't need Ken's bushings as you can go with the Yamaha OEM spec bolt you already have and won't need Ken's bushings but could probably use cut pieces of metal or washers as spacers for the shock. If not......then it's just like a 400ex and then you need Ken's bushings and 10mm bolt. I'd just pick up a 250R shock first and check it out and see what it looks like and what fits.

kens bushings are for the top only if needed , i used them up top, cause i didnt know that bushing came out
drill the bottoms to match a bigger pin
 
think my sons is an 87trx, same as yours, not atc.
and i just drilled either the bottom mounts or the bottom shock eye to the same size as the bigger of the 2, then take the shock to ace hardware to find a pin to fit, measure how long you need, and yeah i think i used washers as spacer between the eye and mounts, works good
