My 1982 DOHC Honda bike has buckets and shims and I adjusted the shims a few years ago,I guess you could call them solid lifters,I can't see anyway they could be hydraulic. I have never heard a noise from a Huyandai starting up and we have 2 of them and they are getting the ks up on them, though not much these days seeing we are not allowed to travel more than 5 ks from home.
