Super 8 / 2008 Super 8 50cc 4-Stroke De-restriction advice
« on: April 27, 2011, 01:01:55 PM »
Hi All,
Sorry, I'm a newbie here so I may be asking a question already been answered. I purchased a Kymco Super 8 second hand for my son and I want to improve the top speed. I have read a lot of posts on a number of different forums and I'm getting various answers about what I can try. I understand that there are a number of mods that I could make, as follows;
1. CDI - cut one of the pink/violet wires or replace with an unrestricted CDI unit
2. Variator Boss - Replace the tapered boss with smooth boss
3. Variator rollers - Replace the standard ones (what weight?) with lighter ones for better acceleration or heavier ones for better top speed.
4. Carburetor Main Jet - Change the size from 80 to 82 or 84
5. Carburetor Air Flow - Remove the plastice restricter from the back of carb.
6. Exhaust - Remover the restrictor (if there is one) or change the exhaust (Leo Vince or similar)
I have checked the CDI wire and this has already been cut but it doesnt seem to have made any difference? I even reconnected it to see if that made things worse which it doesnt seem to have? My questions are
1. Does anyone know why the CDI wire mod doesn't work
2. Can anyone recommend any of these work best as I dont want to waste money on ones that dont
Thanks Dave
