well I know for a fact I won't be able to align them wheels using markers on the frame. I'll give it a go tomorrow with tape measure... any tips How can I balance the bike in the air? as at the moment I'm leaving it on stand fitted to the bike I have none of them fancy bike stands and another one.. how close it has to be to pass MOT... I've got a deadline for retest for Monday after work so would just like to pass it till it's free (2 weeks free retest) and then take it to the garage and get somebody who knows what he's doing to have a go... It probably is like you said loosen one bolt.. push this way and tight it back up for somebody who knows what he's doing it took me good 15 min to figure out which way I need to move the wheel once it was loose to get it in line.. but then like I said... the chain beginning to be an issue as I need to pull the wheel too far and chain getting to tight.
