Sad pictures to see for sure Pete. Glad you and the rest of the bike are ok.. Maybe Zippers will help you out with some sort of policy adjustment and get you back on the road soon.
Thanks Bob. This isn't a Zipper's problem, they built me a real nice motor that actually exceeded performance expectations and I can't criticize them for their policy. I am probably one of a few that run a big inch motor in a touring bike and use it to go fast (and often) as well as pile on the miles (20K+ per year on average). In all other respects, the motor is in perfect condition. Of course I am metriculous in the maintenance because I know that is how to build longevity, but I am perplexed as to why this keeper failed. That actually bothers me more than the damage itself. I certainly don't want this to happen again and I intend to speak with them about it when I take the motor to them on Monday. Maybe I will find out something useful about keepers I can pass on to others.
I expect to be down for awhile. As Don mentioned this is not the best time of year to have a problem like this. The Zipper's piece of the work is not the issue, but the new head and cylinder needs to be diamond cut, head, piston and valves thermal coated, etc. before final machining, fitting and assembly can begin. The crank will have to either be rebuilt by S&S or replaced entirely, rebuilding will probably take longer. All in all, the rest of the motor needs to be broken down and examined before I know what path to follow. Stay tuned.
Now I know why people own at least two bikes! Maybe this was an omen to get me off my arse and find an SERG!
