Shocks are a maintenance item. They must be maintained and serviced same as your clutch, exhaust valves, chain case lube, fuel filter, belts and more. My sleds don't leave the shop, from new, with WE oil.
There are thousands of PROs out there since 2011 that have not had there shocks serviced. Shocks should be serviced, at a minimum, annually. Your riding style will dictate the service interval. I service my personal sleds shocks anywhere from 300-500 miles. If you are a savvy rider you will know when it's time, you will witness a change in RTS rebound first. You need to service all four shocks at the same time. I can't emphasize enough the WE shock oil is a very poor oil. If you service a Stock PRO WE shock with less than 100 miles on them you will find contaminated oil with a substantial amount of wear residue stacked up on the floating piston.
You will hear from dealers that you need to give your shocks a 300 mile break in interval. That's wrong, springs need a break-in period. Your stock WE shocks are toast at that mileage. You need good oil to start with. That is why I recommend Amsoil 5 weight. Look for a discussion on shock oils we did around a year ago. There is a thread pertaining to shock oils.
Geo, is correct, you must keep up with servicing your shocks if you want that ultimate reaction/ride from your suspension.
Now let's get to components. FOX, in my opinion, offers the best valve shims in the industry. When you replace the shim stack use FOX shims. Much of shock fade and poor performance has to do with valve shim burnout. The only size not available from FOX is the 1.20", you must purchase them from WE. In all reality, most FOX components will fit your WE. So why is a FOX shock superior to a WE?
We spend hundreds of dollars on aftermarket shocks, when in reality all we need is an affordable revalve. Now when you revalve, you must be honest with your tech, every discipline takes a different build spec. You can't take snow cross specs to the mountain or vice versa. You can build a happy medium, but if you want a boondock setup specify it.
Now onto "clicker" shocks. Let's be honest with ourselves. How many of you that have the clicker shocks know if they are compression or rebound adjustable? Do you adjust them for the ride in and out on the trail? Then adjust them for the days ride in the powder. I doubt it. I'll bet most "clicker" owners haven't touched them or adjusted the springs. No matter how you adjust the stock WE "clicker" you cannot slow the low speed rebound. The IFS shocks once loaded will unload you faster than you can compensate the action. Believe me, I've been there. As stated in another thread, I played with my "clickers" and tossed them for a set of my revalved mono tube WE. All is good now.
If your shocks are doing their job, the CG will be closer to the center of your sled. i.e.: over the front torque arm. If not your CG will be closer to the rear torque arm. Think of it this way, when you launch big air, do you personally move closer to the front torque arm for that flat landing or the rear torque arm?
OK, I need to get back to porting my weed eater.
