Thanks for the advice guys, this is probably really basic stuff but I've only just started out so appreciate your responses. I adjusted the clutch cable earlier on and went out on it, seems to have made a difference. Its slipping less than it was, in fact it only happened once, so I pulled over and gave the cable a little bit more slack and it didn't happen again. Will go for a longer run tomorrow so I can get up to speed and see what happens, if it all goes wrong I have breakdown cover! Oh and the haynes manual is on its way for when I do need to do some work on it.
