    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!

    Thanks

    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

    So glad to be swapping them out for some bullet proof lightweight goods.
