  1. Hi all,

    After some advice, I have a slight weep of coolant from the larger freeze plug on left hand side of the vertical cylinder. Only trouble it’s the hardest one to get at to replace because of the frame being in the way. Has anyone had this problem. Can you tap them in on the angle or is it a case of dropping out the engine

  2. Looks like fresh Motul 300V to me.
     
  3. I’m pretty sure it’s coolant, as I believe the plug is there in case coolant freezes. I might be wrong? It’s not oily to the touch either.
     
  4. It does look like a freeze plug, is your coolant green?
    You really need to tap them in square with a bit of sealant around the edge
