® Whose Article is This?

The article you are about to read seems to be a popular one, if the number of times it has been copied elsewhere is any indication. At one time there were over 10 sites that had it duplicated word for word. Here is an example. At least they left my name on it! The piece came out of two things. First, this is the same tool we built at Motorcycle Mechanics Institute when I worked there as an instructor. Second, the incident described is real and happend at my then workplace, Eastside Performance Motorcycles, in Mesa, Arizona. The machine was a ZX11, one that had just had a big bore kit put in it by another mechanic. I got the idea of lowering the pressure and rotating the crankshaft from something Smokey Yunick had said, many years ago. It worked. We replaced the bad cylinder sleeve in that engine and pulled the oil pan and retrieved the piston circlip. Made me a hero that day in the shop. Those of you wishing to use the article, why don't you just link to it instead? At least ask before taking it and putting it on your site. How do you think it feels to see your work claimed by others?

  Some of the current offenders (these folks never asked, they just lifted it word for word)

  • KZ650 website (though they screw it up at the end)
  • VMax website
  • And these guys link to the VMax site
  • And also here
  • And this site stole my drawing

Another article the VMax folks have posted without permission, this one on my version of Pierre DesRoches' fork tuning method. The odd thing is, this particular article I wrote back in the 1990s (the drawings were done in MS Publisher, remember that program?) and never published. I inadvertently used a printout of the article to wrap a shipment to someone, and that person gave it to someone at the VMax club! On New Year's Eve 2012 I included it on my site. :-)
