That is good news; thanks Major. I will seek it out. Adams's death (by exercise) was a huge tragedy for me, only ameliorated by my ability to re-read his books and find at least a few things I had forgotten. (This is a little recognised advantage of advancing years. I wish I could think of others.)

That works out to only 32.3 cents per mile, well worth it.

You forgot to include the cost of the drill though.

Me too. The only thing good about getting old is, it's better than being dead.

[quote="gspd"]I thought I would be rolling it over to (4)00000kms this weekend.
it ran perfectly this morning on the way to the Trenton rally, only 420kms...

...BUT, on the way back it developed a con rod knock.
I limped it home (350kms) at 100-110 km/h while my loyal buddies continued on their merry 150-160 km/h way.

That 's a drag! At least you were able to get home!

It was very embarrassing...I was being passed by Harley clones. :oops:
I think even a gen-new-wine Harley passed me. The horror!

I'm so sorry to hear you had to endure the ultimate humiliation. Recovering from hearing that potato, potato, potato pass you by may require some professional help.


It's fixed

I fixed it today, I waited all week because I had other stuff to do, and because I have the shop to myself Saturday (it's closed).
That way I can work without interruption.
I don't mind if customers talk to me on their dime; when they ask me something I put my tools down and answer their queries. When the conversation stops, I pick up my tools and continue working. Meanwhile the clock is ticking.

I know the sound of a conrod knock a mile away.
Unfortunately when I first heard it I was 300kms away.
I kept it under 4500rpm and rode it home because I felt like it.

This is what I found when I ripped it apart this morning:
The left side shells were toast, right side was like new.
Image
The left journal was crappy lookg but had not overheated, and no deep scars.
Image

I don't know what caused this, both journals were squirting out tons of oil when I spun it with the starter.
Maybe it was a material defect.
I don't recall ever seeing a chunk like that missing from a shell that lacked oil.
I polished it with a shoelace wrapped around it and Mothers chrome polish.
Image
Now it looks like this:
Image
It should last a long time, I am giving myself a 5yr/100.000km warranty (parts. labour and towing) on the repair,
If I did this type of repair for a customer I would warranty it for 5 minutes or 5 feet (excluding parts, labour and towing).
Because I felt like it, I checked the valves and guides; lapped all the valves, guides are perfect.
Before smashing it back together I installed the SS pushrod tubes I've had sitting around for ages, just for bling.
Image

THEN, I changed the oil and filter, and guess what I found....
