Welcome to the site! Be sure and go to your User CP and update information relating to your location, type of riding, etc.
I am going to move this to the
CR / KX / RM / YZ (2-Stroke) Discussion forum. I will get AJ to get you an answer. As the godfather of the current CR500 he likely know more than anyone else on the planet about the bike.
I was going to suggest that you contact
Service Honda, but it appears that you have already found them..
As one of the best resources on the planet, I highly recommend
MX & Off-Road Performance Handbook -3rd Edition - by Eric Gorr. It can be purchased via
this link. I have a copy and have found the book to be very thorough in its’ discussion of the various components of a motorcycle. Eric’s many years of experience are self evident. Additionally,
Eric Gorr’s Forward Motion Racing is a valuable resource for engine work. Both the book and Forward Motion are links in the bar on the left side of the site.
After that grab a spot on the couch and start a new thread in the
