Supertech valve train upgrade question w pics.....
Was curious to know if the springs have a top and bottom.
They don't specify. I would say no but I gotta ask the pros first!

no they're constant rate. As long as they're not sideways you're fine.
Wanna sell that riva tool after you're done? I need to install mine and don't want to buy new

Has anyone had a failure of the stock valve springs or retainers on the late skis? I did see a failure but that was the cam bolts and was possibly caused by the big cam and big springs.

I have been seeing ALOT of stock springs breaking on higher hour skis (175+hrs) also I have seen a lot of stock retainers cracking causing a dropped valve
