Title: KDX Manual or specs?
Post by: Goat on May 17, 2011, 04:57:46 AM

Anyone have a KDX manual I can get in pdf form? Need cylinder, head torque specs and also ring end gap specs.

Got new rings and gaskets. Will be putting it together as soon as I find out the specs I need.

It's a 1991 KDX200 all stock. No Mods.
