I think most of us would love to have our shocks serviced. But, at the cost of close to a couple hundred bucks, most people would rather find another EBAY shock for 50$ that isn't leaking.
I always disassemble the front forks on anything I ride because usually no one changes that oil either. Thats a one hour or so job and 8.99$ for the oil. Most of the time I clean the seals and pop them right back in. It's easy and I have all the tools and knowledeg, unlike the rear shock!
Sometime I have to learn to service the rear shock myself because I have access to free nitrogen on my work truck......
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
