I agree since the top ends are complete and not damaged it appears that it is just lower end bearing failures...
I'm not sure why we are all of a sudden seeing lots of bearing failures
I did have a PowerBloc clutch on this machine - clutch balance issues ?
This machine also runs a little higher compression about 170lbs
I have not ever switched motor oils so I don't think its a motor oil band issue - I run Bel Ray MC1 at 32:1 by the way...
I guess these machines are all just getting to the age where some parts are just starting to wear out ?
I'll know more shortly...
I boxed up the lower unit and sent it to Phoenix, AZ (PCP OffRoad)
I boxed up the upper unit and sent it to Batavia, OH (Bore Tech)
I'm having a few upgrades made
PS
Anyone know where I can get a new set Pro Design Cool Head O-rings ?
PSS
Thanks for the info on why my picts were thumbnailed <sp?>
