SOURCE: would a cdi box cause

Not likely. would cause it to not run. you if this is a 2 stroke you may need to adjust your oil mixture. manual says 30;1 But 40:1 is much better.

SOURCE: Need a ignition wiring diagram for a 1999 yamaha

http://www.4shared.com/document/sMjNLzGr/2003_Yamaha_YZ250_FR_Wiring_Di.html

The link above is the wiring diagram from the 2003 Yamaha YZ250, but I am not sure if this will match the 1999 Yamaha YZ250.

Here is a link to the 1999 Yamaha YZ250 Service Manual, with the wiring diagrams: http://www.powersportresource.com/details.php?mID=237

It is less than $10.00, making it a great deal if the diagram I provided you doesn't match up.
