Has any one ever come across a kick start boss that has had a right hand thread both ends, wondered why the left hand thread kick start bolt wont screw in.
Does seem rather odd —
Any contact from the kick start would unscrew the boss —- not good engineering practice!
It must have cost someone a lot of money to have made,just think how annoying that would be to find out it was no good as they had put the wrong thread in it.
The strange thing is, that most machine shops ask for the the mating part to ensure a good fit to the thread, unless of course they made both the boss and the nut?
