I used the bagpipe andy kit this week - wanted to get it in before the 'arctic blast' hit us.
Not too bad, took longer than I thought, the hardest part was holding the compressor back in and getting the sequence of washer, rubber, washer, nut back on each mount.

It's so much faster now. Seems a bit quieter too. My front shocks leak, so the camel is sitting on its knees in this cold, however, it would take the full 2 minutes to climb up previously, and often it would take a few cycles. Now it does it in under a minute!

New arnott air shocks are sitting in front of my desk here...waiting for some warmth

Thanks Andy, much better than dropping $500 for a new one!
