I am planning to mount a wide tire kit (2k) from Sip with 130/70/10 tire. Now I understand that with this kit you need to cut 10mm off the swingarm and add a spacer of 10mm on the other side. I have read on a few forums that to have the rear wheel exactly in the center you actually need to cut off 17mm and add that to the other side. Can anybody confirm this? Does anybody know if my bitubo in the back is still going to work OK if it is not haging strait anymore? will it brake at certain point? And finally, if I move my engine out 17mm will I still be able to put my engine cover on?
