Possible antifreeze leak?

[Fazerjon]

I agree that it would look much better if the outlet/return holes were blocked off, I will see if I can find something suitable to block them off. Regarding the AIS removal, I found an American company called TPO Parts https://www.tpoparts.com/cat093/index.ph...oduct_id=3 which do a similar kit without the need to tap the holes out for around £20 inc postage! Ive just ordered mine so will let you know how it goes.
Thanks again for your advice earlier, I think thats the end of the coolant leak!
P.S have you had any running problems with the carbs during the cold weather?
