Much of the primary can be "serviced" right on the sled. No special tools needed to change the spring or even change weights. From there its easy to blow air through it, check or free movement and such.
Servicing the buttons will require spider removal but you can even fab up some tools as shown on youtube numerous times.
It was a sh!t show, took it to a dealer, paid around $200 I think, first day out the clutch started rattling really bad, buttons were coming apart on the spider, rollers didn't look great after that either. I'm not sure if it was sh!tty install or sh!tty parts but I ended up buying a good condition used clutch and took the other one back to the dealer, they refunded my money.
