The reason we developed the Rock Armour was due to out air bag getting a hole in the bottom of it in 2015. We went through the dealer who said it was a bad compressor and they replaced it. 3 weeks later the new compressor went out. By then the dealers in our area were so booked up it was going to to be 3-5 weeks to get it repaired. Instead of waiting, I tore it down myself (with a lot of help from here) and found the hole in the bottom of the air bag by removing it and bench testing it. I contacted the dealer that had missed the leak and wanted them to swap out the bad airbag and or course they said that if they didn't do the work, start to finish they couldn't help me.
I ended up putting 4oz of green slime into the bottom of the airbag while it was off the byke. I then purchased a aftermarket compressor (Walmart $75) a Viair 98C and put it all back together.
For 3 seasons (starting on the fourth) it has worked perfectly with no problems at all. The other day we went for a ryde and the byke has sat for about 3 weeks. When I started it up and pulled it out, the compressor kicked on for about 2 seconds to freshen the air and that was all. I have no idea how long it will last, but we'll keep running it that way.
Here is a link to some of the repair videos back in 2015.
And, btw, I was at the dealer down South the other day and telling the parts guy what I had done and the service mgr overheard us and told me in no uncertain terms that putting the green slime in the air bag voided the warranty on the bag. I just shook my head........
