Yes........you can drop the front 2" thru the trees with no problem. As long as you are not running handlebars.....probadly have to go with clip ons. I've done this on my race bikes, when running larger forks.
Spacers on these forks will not work due to internal setup of the forks. Only way I have ever been able to lower these forks with keeping them level in the top triple tree, is to cut down and rethread the internal threaded push rod that screws into the fork cap. This lowers the fork tube, but still gives full motion of the internals....to allow for proper funtion of the fork.
