You could also try a split collar
I had no idea what one of those was, so I searched it and the images look *just* like one of the products I sell...!!!
Well, anyway, I haven't, yet, managed to shift the sleeve on the bottom of the rear shock. I tried heating the bracket that holds it, then zapping the inside of the sleeve with some freeze spray, but it didn't want to move.
However I have finally managed to get all the brake pipes off, although that was a palaver.
There are another couple of screw connectors just above the gear box, but I was unable to get them to move and one started to round off.
So I decided to try heat on the ones at the front and, after putting some aluminium foil behind them and then a wet cloth, I heated them up and, joy of joys, they shifted!
I did also try this on the ones in the frame, but didn't have any luck with them, so, instead, I decided that if I could wiggle stuff around enough, I might be able to pull the hard lines and the hoses to the ABS modulator out via the front of the bike.
Sounds simple, but it took me over half an hour trying to get everything through tiny gaps...
Anyway, eventually I got it all out, so I might have another go at freeing the screw connectors tomorrow or, if I feel up to it, having another shot at the rear shock.
