Yea the Showa's aren't great but better than the Marzocchi. I guess you need to weigh up the cost of modded Marzo vs Showa. The spindle size and caliper bolt spacing will probably be different to what you have on the later ones, it's doable but again you need to weigh up the cost of new calipers, axle and wheel bearings. If the 600 is a keeper then maybe a worthwhile mod or if you plan to upgrade to a bigger Monster then just cut your losses and get a 900/1000/S4 and get alll the good stuff included.
