I think the best way to hitch to your bike would be to make you some new chain adjuster blocks that have a hole to mount the trailer to. Similar to the setup I have on the KLR650. Do you have access to a pair of calipers to accurately measure your current chain adjuster blocks? It would require you remove the rear wheel and take a few measurements for me. I can email you a drawing with the dimensions I would need if you are interested.
