The only way to find any problems or things that need to be adjusted is to test ride. Just make sure that the front doesn't sit too much lower than the rear or you get alot of darting from the skis, due to too much ski pressure. If this is the case, just tighten up the front shock springs and loosen the M-10 shock springs. Should make a world of difference on the trails compared to stock. One more thing to check: If you have jacked up the front you may need to modify the rubber piece between the ski and the steering spindle. Jacking up the front will cause more pressure on the front of the skis which will kill your ability to turn, there wont be enough pressure on the actual carbide. To fix this, Take off the ski ( be sure to remember which side of the rubber bushing or spacer (whatever they call it) was facing forward) then shave approximately an 1/8 of an inch off of the bottom of the front of that rubber bushing at a time and put that shaving under the rear of the bushing to balance it out. If you have the front of the sled off the ground, you will see that the ski will sit more level (instead of them angling down towards the front).
