(on my triumph sidecar rig). it tracks pretty well now at 65mph but in right turns the sidecar comes up too easily.
i checked camber with a level (which is magnetic and attaches to the disc brake nicely) and noted i have to tweak that.
right now, the bubble indicates 'lean in' which is exarcerbated when i sit on the bike.
the bubble should be displaced to the left (lean out) which should help right turn stability.
note: photo taken looking aft (front wheel, left side).
the rig should be level (bubble centered) when fully loaded.
i'm guessing this applies to beemer rigs also.
