I often run 36psi on entrance, 42psi rear.. additionally, psi could also be depending on what tires you’ve gotten.
Might you share some extra particulars…
Mileage?
was it garaged?
Has the HES been changed/ upgraded?
Tire age and situation?
IIRC, these have been basically a R1100, however with 850 jugs. These have been comparatively uncommon within the states. I feel they make a pleasant roadster, and if as dependable as my 1100 oilhead, and good experience.
