Hi Ade, i've fixed the wobbling loose crank issue using Oilite type porusppl bronze bushing with vertical oil hole feed thru mains cap drip sight tube oilers, ensuring adequate boundary layer lubricant type (i like ptfe additive package) & feed rate control with all wobble eliminated (0.0015" clearance). I also added oil hole lube feed to factory con rod big end  brass bearing shells. All cranks should run so smooth & quiet !! Next,  last lube issue is to add a piston drip oiler hole to cylinder liner. Thanks again for helpful info,. tom.
