This is from an XL250R service manual, it should be the same, and sounds like what you're describing. *shrug*

I just did this on my own bike, and I ended up shoving a flat screwdriver down between the chain and tensioner to get the dealie up far enough to get it with a pair of vise grips. YMMV

I use a small pair of needle nose vise grips to grip the piece that comes up when the wedge is realeased.

You have to pull it up really far to see it on mine, let alone get anything through it.

Parts fiche says they're the same part: http://www.cheapcycleparts.com/produ...oner-cam-chain

The 250L tensioner is the same as the 250R. You have to push down on the front wedge to release tension on the rear wedge. While you are pushing the front one, grab the rear one with vise grips and pull up until you see the hole in the wedge and slip a cotter pin or a HD paper clip into the hole. If the chain is extremely worn, it can be difficult to get hold of the rear wedge because it will be deep into the tensioner body. It makes things easier if you remove the tensioner set plate first. If you continue to have difficulty, PM me and I'll go into detail.

thanks for the offer, Creaky

a Michelin tire iron, a large screw driver and a set of vice grips later the cam is installed

but:
no hole
no matter how far I pull
had to keep the tentioner 'relaxed' with the vice grips
