For me, having the physical specs of my shock and front/rear springs changed everything, and allowed me to look for replacements on my own. I quickly realized I'd have a hard time finding an integral-reservoir shock that fit (solution: Zero optional Fox shock) or springs that were correct for my weight and riding style (solution: Cannon Racecraft).
Re your shock:
Y.S.S. has 3 monoshock models without reservoirs and 5 with remote reservoirs, are available in all sorts of lengths and lower mount options, and come fitted with spring & valving determined by a program using input from a short form you fill out online with swingarm measurements, riding style, weight, etc. I can pretty much guarantee at least one of them will fit your bike and work well. The Y.S.S. shocks on my vintage bike are at least the quality of the Fox shock, maybe better. My
shock installation thread has spring details etc. Bear in mind that since hardly any Zero component substitution will be a drop-in replacement, you may need some custom spacers etc. made.
As I've posted in my fork threads
one and
two, fork springs aren't hard to upgrade once you have the dimensions and initial spring rate (calculated online using spring measurements & coil count). Once you've decided on a new rate - say, 10% softer or whatever -
Cannon can hook you up. The Red Line LikeWater oil also made a big difference, especially on sharp impacts. IMO it's critical to set
all compression and rebound settings to zero, otherwise the thinner oil won't make enough of a difference to really be worth doing.
