I installed a brand new Predator 212 on my Doodlebug with an OldMiniBikes adjustable mounting plate. New 12T clutch from OldMiniBikes as well, not a Maxtorque, just a basic one. Also replaced steering neck bearings and wheel bearings,
Just puttering around at low speed is fine, but as soon as you give it 1/3 throttle or more it vibrates like hell, like vision goes blurry vibration, until the clutch fully locks or it hits a certain rpm/speed as far as I can tell. I've double checked my chain tension, I've checked all of my motor mounting bolts, I've made sure my chain is aligned, just put new tires on. I don't know if this is just how it should be or something is just way out of balance?
Very familiar to this post - https://oldminibikes.com/forum/index.php?threads/predator-engine-shakes-bad.55626/
Anyone have any input on things to look for/check?
