Riding the other day I found the clutch lever would stop before the handgrip . Still engaging and disengaging correctly I tried adjusting lever but it had shorter stroke .  Cheers to mototrials west whom said check the through bolt at the centre of the clutch basket .  It had wound itself out , once I chased the bolt threads it went back in and all works correctly again . Bonus is it’s a reusable gasket on the case . A small side note this is the first issue I have encountered  on this 2017 vertigo 250 I bought new 

Thanks for sharing!

I have similar experience regarding reliability: in three years just one small oil leak (shaft cover just in front of the sprocket).
