The oil weeping from my pushrod tube seals (both sides) has progressed to messy leaks that I can no longer ignore. Both local shops want ~ $750 to replace them. Can's swing that, but have not torn into my motor at that level...yet! I assume the seals can be replaced by removing the heads and not the cylinder sleeves. How hard is it to do?...will study my Clymers, but any tricks to be aware of? or special tools needed?.

I think once the heads are off, I could have the shop inspect the valves, etc. Have not had any problems with them, tho.

Once the heads are off, does it make sense to go ahead and pull the cylinders and do the rings and base gaskets? The bike has 40k miles and I do not have the PO repair/maintenance history.

thanks for any words of advice...
