On the rear mounts I altered one bracket and lined up the holes by pushing the tank forward with a lever. Are they all this difficult?
On another note, I found that the Acerbis locking gas cap works on the IMS tank - may be old news, but feels better when taking long trips and leaving the bike unattended.
I installed a Acerbis 4.2 yesterday. Went in with zero issues. It has dual petcock so it emptys fully from both sides. I thought I had a issue with the tank hitting my riser bars but then I noticed the previous owner had put the adapter blocks on backwards. Once I revesed them to the right spot I had full lock with not hitting on the tank.
