the knockoffs have been hear since the 80's .most I have seen and used are far better than most places will/can grind them..even the big guys use some offshore cranks with thise names on them. heavy metel is expensive and a good reason for light weight parts as well as crank lighting in the right places. I dont plenty of heavy metal in many different apps. and seen the moron way fo doing it in "promod engine" musta been a budget engine with used up parts. it was one of the funneyest thisng I had ever seen... 1 inch wide by 1/4" thick steep strap welded around the counter weights....wtf?? and much more than that throught the engine. as for the crank finish of the imports,Ive never had any issue with them I always polich befor assy and set the clearances where I want them( tight side, with thin syn oil) and coated bearings.OH How I love coated bearings. I think they may just be indestructable....well almost. I probably still have some mallory around hear somewhere... Ive even seen it installed by drilling down into the counter weight and pounded in...and...flung back out...you cant fix stupid. I think I still have the reamers for installing them correctly hear at home. I miss doing all that stuff.and racing too.
if they hit the piston skrt...the skirt is in the way.and weighs too much...time to lighten it.:) and or the rod is too short. probably both.
