    Svho spring upgrade

    Anyone know if this is true? Ebay guy says you can use kawi inner springs along with your stock svho outer and it's the same as the riva/r&d valve spring upgrade kit. http://www.ebay.com/itm/152341141147

    Just so happens i have a ton of kawi extras and would be sweet if possible.

    Very bad idea!


    MWHC, If you want to upgrade your valve train just do the Riva titanium retainers. They are proven to handle 9400+ RPM with the stock springs

    Figured it was a bad idea or it would have been talked about already, just curious if anyone tried it. Sounds like they have and it's more ebay snake oil

    I love the eBay computer chip that adds 15 hp. Works 100% goes great with the muffler bearings they told me to replace in order to prevent the seat from falling off at idle
