Re: SCRAMBLER 50 CHEAP MODS
The foregoing mods only apply to the 50cc model, especially the head mod as the 90cc head MUST be replaced completely.
The K&N filter "RU-200" can be ordered from any shop that sells K&N. Heck, you can order it from Kragen Autoparts. If you want to have it shipped with an outterwear, call Trinity Racing. 714-632-3434.
On the 90, remove the restrictor sleeve located above the carb slide, add the K&N and drill the main jet to .032" to start. Your next mods would include a pipe, head and cylinder height change.
