Valve springs and retainers only take so much use even at a low stress street use and the we already have slipper thin pistons, hollow cams, , factory knife edged cranks and polishing...I feel if they do continue on that wew ill see a drop in reliability or at least higher maintenance requirements?!

Hmmm... maybe, but maintenance levels/requirements have dropped significantly over the last few years. Heck, my bike requires oil changes every 5,000 miles with the filter to be changed every other lof. Shit valve adjusts supposedly every 15-30,000 miles, I've never done one. I don't know bro, but reliability, at least with my bike, has not been an issue. If I'm not mistaken, the Yosh stage 2 mods don't even void the factory warranty!!! I'm pretty sure that the GSXR1000RR is covered by the factory.
