I too have heard of the bearings in the crank leaking. Is there anyone out there who may express how many tanks of fuel they ran , what temperatures thier motor maxxed out at and what carb settings they had while the bearing failed as they were running thier .46 engine?? I love BOCAbearings and they have any bearing you may need should you need it. I own a 2nd generation Genesis and I have never had any bearing leaks in my engine as of yet but I would like to hear from all who have experience with the Genesis and leaky engine bearings.. THANKS,,Peace "O"
