Jon,
Your query about the centre stand begs the question 'Is your bike still fitted with the spring clip and backing plate?' This clip and backing plate attaches to the front lower rear mudguard bracket - it retains the stand in the up position, but more importantly, it allows you to use the footpad on the stand to lower the stand to a mid position before putting your boot on the foot of the stand - thus making it easier to lift the bike onto the stand.
Whilst most Mark 5's were fitted with the narrow stand, if yours has the optional 'waffle box' exhaust, you can fit the wide stand that was standard on the Mark 3 (I think Club spares are trying to get another batch made).
Regards,
Eddie.
