Right im going to give this a go fitting these to my1997 1100 gs. I have been doing a few little jobs on the bike and ejoying it plus saving money. I have watched a few videos and think i could do this but the one thing i am concerned about is phasing it back up into the bike, so when i take the final drive and extension out of the bike should i mark the extension at 12 oclock. Then when i replace it back into the bikes propshaft at 12oclock will it all be good. Help apperciated
