i know that NemPro/brad/evil4bc has been doing this for a while and selling them, and that other people have done their own. it would be rad to see some close up pictures of the internals and what has to be modded. the distributor BTI, ww.bti-usa.com, sells fork tuning kits, but i don't see any of them designed to drop a dirt jumper fork from 100mm down to 80mm or 60mm. what do yall do, buy one of these kits, then cut the springs shorter. or just use the interals that are already in the fork ?
