cynic's right about the way the bike looks.
my tester actually told me, if the bike looks neglected or has obvious faults, he will make sure it fails coz there will be other serious faults in there somewhere.
took my tracker in wednesday.
tester " wow that's nice"
me "cheers, got no lights, indicators and a cut down exhaust"
tester " yea, but its looks great"
I wait 5 mins as he checks brakes, then we have a chat about what i've done (he is wasting time as the computer times the start and end of test)
passed, with an advisory has "no lights"
