So much for that new top end!  Oh well at least it made through the Paris weekend.  I was on my way to the Canadian Super-bike race at Mosport Today. She was running great and the old thing just locked up at 65 mph. Looks like the oil pump has problems. Any idea's as to why the pump failed and what to do next to resolve the pump problem would be appreciated. (Yes, lots of oil in the tank.) I think the bores are OK but 2 of the pistons are junk.        |

Jim, that really sucks man! Hows the filter screen look in the tank? Does oil flow freely to the oil pump from the tank? |

That's something I haven't got to yet.
I'll check the flow at the pump connection.
I guess I'll have to remove the pump and check the drive to see if anything is messed there.
I was told that the pumps are very reliable but I'm not up on how the drive train works.

I think it was probably starved, but it's good to take apart and examine the pump. Mine had sat for so long, the oil/dirt/water congealed like glue and seized the pump, so I HAD to take it apart.  |

That's too bad!
The oil pump drive is directly meshed with steel gears (both) to the crankshaft. The tach drive is a plastic gear driven from the same gear/shaft that turns the pump. Provided your tach was still working when the seizure happened the pump was still being turned.
Air is getting into the oiling system from somewhere. It often is the inlet supply banjo fitting. If the oil inlet in the tank was clogged the pump might suck air through one of its seals (or from the aforementioned banjo)
Have you been noting the rate of oil consumption during operation? Like resetting the odometer on a car each fuel up, and knowing how far a tank of fuel will usually go. If the mileage changes something is starting to go amiss.
The pumps usually are good unless corroded/clogged internally. Was the operating cable properly rigged/working?
IMHO, I'd disconnect the oil inlet line at the pump and confirm oil flows well to the pump before disturbing the system further to try to better find the starvation cause. If this shows little/slow flow you will know for sure there is an obstruction somewhere to the pump.

That really sucks Jim. It's not like the bike was sitting much either. You'd think a pump that sat idle for many years would be more likely to calve. |

Ouch! That sucks big time Jim!  Glad you didn't high side it or something! Where did it happen? Any indication it was ready to seize? If you need some CMM measurements for size and roundness just drop them by and I'll check them for you. |
