So I was doing some measurements of the OEM engine guard and it seems like the diameter is 40mm. I couldn't find it in any specs so I measured it myself and it was 1.57 inches. Bah to finding anything that will fit it. I was looking to buy some stash tubes, but finding one that fits will be a challenge unless I jimmy rig a clamp (which would look cheap and ugly).
I keep seeing other bikes on the forums with the OEM guards and they have stash tube clamps. Anyone know how they did it? What was the size. I might buy some 1.5 inch clamps and see if they fit.
