2003 Scrambler 50

I can not find the restrictors on my scambler 50. The thumb throttle screw has been removed. I have herd of the exhaust washer and the double jets in the carb. I have checked both places and can't find any thing. Any help would be appriciated. Also does anyone know about the 03 cdi, I have herd it will allow the bike to rev to 9000. Is this true and if so is it nessasary to replace it unless hard core mods are made.

Re: 2003 Scrambler 50

hi, the exhaust restrictors at the head and back of the mufflers have been removed on all 2003 polaris youth models in favor of a new cdi box with a removable restrictor. the new cdi box has two screws that have a jumper wire between them. when installed (like it comes from the factory) the speed on the 50 cc is limited to 10 mph. remove the jumper wire and it will increade to about 15 mph. a trick i used on my son's 2002 scrambler 50 was to put a 2002 scrambler 90 cdi box in place of the stock one. it plugged right in and really allowed it to rev out. i haven't clocked it but i'm guessing we got another 5 or 6 mph on the top.
