great tip. this should save some people money, better to do this than buy an aftermarket shock.Guys,
In all my testing, the grom/MSX125 forks need 30wt fork oil. I use Spectro, and I mix my own. The forks respond well to added air pressure, 12psi/15psi, and I weight 190 lb's. Just a thought, until you replace the rubber bushings in the swingarm, don't waste you money on an aftermarket shock. The swingarm is so bound up by the bonded steel/rubber bushings that it will not make a difference.
