How to turn Jeff's rear shock spring for the 2004 WR450 lowering link setup

Jeff from Nevada asked for some setup advice on his 2004 Yamaha WR450F suspension. Our reply.... "I always use my hand to turn the shock spring. One side of your bike will be easier than the other to slip your hands in. Make sure the threads are cleaned and maybe put some lube on the threads so the spring turns easier. One complete revolution is about 2mm. Six mm is .25 inches."
