Quoted from their site:
This front-end conversion search is based on bearing size ONLY! Stem length may be vary from machine to machine making some combination's unworkable. As a result of front-end conversion, rake and trail may be altered, adversely affecting handling of the vehicle."
Now here is the link. http://www.allballsracing.com/index.php/forkconvertion
What you do is Select TYPE, then YEAR, MAKE and then MODEL. It will take a minute to load, as it is loading every possible conversion imaginable, then just scroll down to the year and make of the forks you are converting to. It is that easy! Just keep in mind to check your steering tube length matches what you are converting to, as this does not discriminate or eliminate those possibilities. It just lists the bearing dimensions.
It can also be navigated to from their Home page. On the right hand side is a YELLOW box labeled fork conversions.
I called them up today and the fella was very cool, and pointed me to page. This opens up a ton of possibilities as long as the fork tube lengths work with the heads we are putting them in.
