I got offered a aftermarket CDI box of $35.00 I was wondering if that would be a good idea and i will be finding out what brand it is. He claims it raises RPM level and increases the timing to some where around 6 degrees. Would that be a bad investment? It came off of a 02 400ex and i have a 04 400ex with a DG slip on, jetted with K&N's. Seems from what i have read that the aftermarket CDI boxes really wake up the 400ex is that true? I have also been considering a smaller front sprocket. Where i ride is in sand pits and threw the ditches alot. If any could give me any "performance" pointers and yet still be a reliable machine i would appreciate (sp) alot... Thanks
