I really need help to find restrictors on the 50&90 predators to gain a few more miles per hour. pictures would be helpful.
thanks

 

on the 2 stroke units you had to remove the wire tab from the box up under the front plastic.its right in the front under the nose piece and on the left side. its a small rectangular box with 2 screws on the side. loosen them up and ratote the tab upwards and tighten the screws back up....on the 4 stroke models there is no restrictor other than the throttle stop on the handlebars that you adjust

 

Should be small plate on cdi located above air box secured with 2 screws, loosen screws,remove plate and will have full power. Also should be screw and locknut at throttle,can adjust for more/less travel.
