thanks forthe info - i think i'll keep them as the one thing i don't like about the 748 is its riding position viz a viz the ultra low bars. however, i think i'll put the bike into a garage to do the work as i'm the world middleweight bolt rounderoffer and thread stripping champion. i don't mind bodging the bandit but i don't want to defile the 748 with my appalling spanner work!
