This is my first post so please excuse me if I'm asking a redundant question. I recently purchased a 2005 DRZ400SM. The bike only had 1,500 miles when I picked it up this past weekend. The owner did some performance mods and essentially parked it. Bike runs good but the suspension is collapsed under my 240lbs. I've done nothing to the front forks and they are not too bad but I will adjust them a bit more this weekend. I did put 3 turns of preload on the rear spring and dialed adjusters all the way in and out to find a baseline setting. I have the rear shock low speed compression set at 9 clicks out from closed out of a total of 27 clicks. High speed has a total of 4 complete turns I have it set at 2. Rebound is set 14 clicks out of a total of 23. This is still way too soft. My question is can I achieve decent suspension for my weight in the stock configuration? The bike sat for so long that the bottom out bumper has dried out and cracked so I'dd like to remove the shock and replace that piece and possibly add a stiffer rate spring? However, I am trying to avoid a huge expense in suspension mods. A Moto Suspension company quoted me approximately $700 to service and add stiffer rate springs on both ends. I can buy the springs and install myself for a much more reasonable price but will the rear need to be revalved? At any rate, I'm just looking for some DRZ-SM suspension blog, advice, videos or solutions on the cheap. Thanks!
