KDX Manual or specs?
« 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.
It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.
