Good morning.
After seeing Philip’s post I ordered a set (non onboard controls) from On Air. Non ahc.
Instructions was to remove wheels, springs and bump stops, but i fitted it by jacking up lc, forcing air out of bags and pushing them through the spring gaps.
Supposed to feed pipe up, but i flipped them round as there was already holes at the bottom and the extra fuel tank made it difficult to see where the air pipe will come out.
Did not at first cut the bumpstops as i wanted to check the hight. Eventually cut about an inch off- might go further if needs be. Photo’s are pre cutting so squashed at the top.
Had bike rack and camping gear loaded and feels much better now.
