did the tubing have a ovel shape ? - where the bars black ? what type of pedals ? plastic or metal
what was the chain ring like ? big disc or a star shape ?
what where the grips like ? what colour where the forks ?
a mk1 burner has round tubing and a two holed gusset weld plate
a mk2 has ovel tubing and no gusset plate
they did do a blue burner mk2 on steel wheels with black bars and black forks
of course parts could have been changed over in time - so it might not be as you remember ?
