i just took out the skid to install a new rail, i put it all back together , and the back sits up high enuff to put the front of my shoe under it , my straps are loose , i loosened up front shock to see if this would help , and nothing , this thing sits up from the two front wheel back its off the ground? how do i push the back down ? my straps are 1 inch thread showing, im 220 pounds , it looks funny , ive never seen a sled sit like this? seems like the ski's will be off the ground all the time and i wont be able to steer? please any info would be great as this is my first srx
