Im new to the three wheel world, and just got a 85 200 x in pretty good shape, except for the rear axle has some play in it there is a nut on the right side of the axle which looks like it can be tigtned or loosened ,what is this there for exactly and ho0w do u adjust it ? i tried for a minute and i cant get it to move an inch. its extremely tight, is there a trick to move this or normally that hard to move.
thanks for any help.
