hi kriss007 or kev

When i had my engine apart i did notice the crank journal's are quite large have you ever lightern and balance this? and what about the balance shaft could this be removed to lose more weight? im thinking of at least 5kg could be lost just doing this! then the lightern conrod and smaller crown piston. and then all the metal removed from gas flowing the head, thats got to be another 2kgs lost.
i know i will be told it cant be done or it has been done!!

If you add some more power, you wont notice the weight so much
its alot easer than trying to remove weight
