Anyway its all built up and running ok, but I think the balance belt is on the tight side as its sounding like I've fitted a supercharger under the bonnet

I had a search and lots of people complaining about it, has anyone had the same problem on here? I was going to give it a few days to see if the noise subsides but if not will need to re-tension it.....bugger.
Unless its possible to undo the 14mm nut and tension without removing the covers?

Thanks
Mark
