MalcombB,
Good catch
, shame about the ribs though... ouch.
It is a bit vertical on my '22 too, not had a problem on flat surfaces, but on grass or when I park in a field to answer the call of nature
sometimes it can catch on whatever? and flip back up easily, and have nearly lost it trying to reposition the bike to find a harder/ levelish spot 'cos it had sprung up when I thought it was down.
For reference it should have a double ( one inside the other ) return spring. When in the fully fwd position the over center nature of the pivot "should? " hold it fwd
...but it is touchy.
If you are going to do the mod as referenced in Gerts post, take it easy and do a little at a time, then remount and check. It does not take as much as in that original post ,that is likely to weaken it too much.
I got round the problem by parking uphill/in gear and also got a center stand and use that whenever I can, useful for working on/loading the bike too.
