I went ahead and installed mono-tubes in my 2012. With the tubes a set of all-balls head bearings and a fork brace was installed. The bike handled wonderfully in turns and tracked straight as an arrow. However; there seems to be no dampening. The bike pogos on light imperfections in the road. I did not install the pre-load shims. 10w oil filled exactly to specs. I weigh 225. Anyone else have this problem and how did you solve it?
