As a matter a fact I am talking about a tm special balanced crank 125 icc engine. when you make the wheels and shafts straight dead on the bearing on the pto is worn to a little over .001 on the journal. Engine has seemed to be a little unhappy pulling much over 13800 my other tms pull 14400 and was just wondering if the crank could be the reason. I remember somewhat the same happening back in the day with kt100. When we ran pipe and twisted the heck out of them, cranks didnt last long.  Thanks for looking Glenn
