Any pictures for us armchair engineers?
This is what I am in the process of doing to mine to stiffen the connnection at the footpeg mounts. (clamps the brackets to the frame)
The rod goes from one side of the bike to the other with just enough room. Hope this helps though yours has a different engine.
Mind you I am a bit frustrated by being away from home for a month now apart from a few days with at least a week to go before I finnish the current project. ( its cool though with helicopters and a mountain involved)
Look forward to your solution.
