left to loosey or right to tighty

[butthead]

hi , can anyone tell me with certainty if the handle bar mirror mount thread on the clutch side of the bike is right to tighten to left to tighten.  i have a mirror stalk in it atm and its been in there a long time through winter and summers, so it will be stiff to undo as a result, but i think one of the mirror stalks is a left hand thread and the other a right, i cant recall which?
  i dont want to strip the thread thinking age has made it very stiff to undo when im actually over tightening it

<after actually checking...>
They’re threaded so they loosen with impact, so the clutch mirror is the righty and needs to be turned anticlockwise to undo it.

I thought it was the other way round and the clutch side had left hand thread so the wind pressure wouldn't unscrew it?

Other manufacturers might but Yamaha have always been as already stated, adaptors for the 10mm thread can be bought to alter thread direction to use universal mirrors so unless adaptors are fitted it is as follows.


Reverse thread & tightens going anti-clockwise for the right hand side, and a right hand thread (standard thread & tightens going clockwise) for the left hand side.

So to answer the OP, lefty loosey/anticlockwise.
