Anyone have any input on different risers for the 900 Classic B? I ordered a set of 4 inch risers but they do not fit the bike unless I drill out the holes on the triple tree for larger bolts. Anyone know of any risers that will use the stock bolts? I think I would like a set of 4 inch risers but I don't know if I want to mess with relocating the cables so a set of 2 inch risers would do just fine as well. Thanks in advance for the help guys!!
