Post by: rodo68 on May 01, 2010, 04:49:16 PM

i resently bought a 93 fj 1200 the front shocks seem soft its real noticable when cornering is this normal, if not what can i do about it. other bikes i have owned had pump up shockes on then i thought the fj might have something available like that for them considering they are such a big bike, any help would be great thanks.

The stock springs are weak at best unless you dont weigh much. Think about upgrading to straight rate fork springs. Many here are running 1.0kg springs and are happy with them...

I'm currently running Sonic 1.0 in '89 forks on an '86. I tried the Progressive-brand springs and there wasn't much improvement over stock - the Sonics are much better (6'3", 160 pounds).

Hey Rod, +2 on what Eric and Rossi said.
Stay away from progressive springs, (that's old technology) and go with some straight rate springs.
While you're addressing your front forks, go ahead and install some cartridge emulators, available (as well as the springs) from Race Tech:
