my rig (triumph with a small cosy sidecar} does not track absolutely straight under all conditions. a road camber may cause slight right drift . wind drag (commences around 65 mph) also causes the same thing. tire pressures (25 psi front 35 psi rear, 22 psi sidecar) are all good.
seems to behave the same with and without a load.
is this the same or similar experience most folks here have?
