Oil Priming Before Initial Startup

   

Cranked the starter until the oil pressure light went out, and spun a few more after that.

I hope to fire her up before New Year's day if the current local West Michigan weather forecast holds true.



Fresh build 84 ZN1100 (low mile) engine:  Wiseco K1172 piston kit, ZX1100A camshafts, welded crankshaft (awesome Ebay find), ported head, APE components, etc.

😜

Very nice, you found it that way on ebay?

 

Last February the crankshaft was listed on Ebay three times with okay side and end photos. 
The one view provided opposite the rotor revealed some semblance of welding work though there was no mention of it in the description.
Repeated views of that photo convinced me to offer the only bid.

There's a little more history behind this crank...

🙂

Well we're listening...what is it?

I followed up with the seller who btw had no idea the crankshaft was welded!

But he did tell me that a long-ago deceased relative crashed the bike with the crankshaft installed during his first and only attempt to race it in the early 1990's.
Said the bike was then parked, and everything was sold over the years.

...

So I buy this old crank with it's essentially new cam chain, and the new looking rotor still bolted to the end...

On first examination I noticed the damage inflicted to the rotor during the crash, and suspect it may have been the cause of it!

See images below:





Judging by the magnet and housing damage, either the rotor or stator came loose enough to make abrupt contact with each other...

The crack trail visible in the magnet appears to extend directly into the steel behind it!

Must have been an awful event to witness...

Good thing the crank was welded...
I removed a small amount of transferred metal from the taper, easily done with a file.
