heads up. Suzuki uses very little to no grease in the suspension.
have you taken apart your rear linkages and pulled the swing-arm ever?
if not, do it asap as you are probably light on grease.
torque specs are in the engine sub-cat of all the nuts and bolts.
i used mobil 1 syn grease.
you also need grease up front at the steering head bearings but those are not as critical as the water soaked rear ones.
