You dont need to remove anything to fit the yamaha Pannier rails. Except the seat.
What you need is the following a cable tye that has an outside diameter the same'ish as the pannier nut hole.
Then you put this throught the hole under the frame look at pictures in above post.
Then you can slide the nut up the cable tye until you have it against the bike frame.
Hold it with you fingers. Tight fit with my littles suasages.
Slide the cable tye out and put the allen bolt into the nut, and finger tighten.
Then get an open ended spanners and slide it between the exhaust and the pannel at the number plate side until you find the nut.
Then you can hold the nut while you tighten the allen bolt...
Then tighten the front one as it is easier to get too.
