The shock on mine is around 2 inches longer than stock, looking through the history it was rebuilt by k-tec using both the original remote adjusters. I looked them up its around £150 for a rebuild. I've fitted the tired spare and that dropped the rear to original spec, the centre stand actually gets the rear tyre up now .
Thanks for the input, will see how bad the spare is, interestingly the spare only has one remote adjuster that came from an earlier model.
