Performance CDI box

Hi, I have a 2000 XR100R (4-stroke) And it is carbureted. Im wondering what's the advantage of having a "high performance" CDI box versus stock CDI box? All replies appreciated, Matt

They make it rev a bit more than the stock cdi

Unless your adding a aftermarket exhaust and a bbr big bore kit save your $$'s there not worth it and I've seen lots of reviews that there's a chance the box will come DOA which means your SOL on electronic items, had one on a 2007 crf100 and I swear it made it idle like crap but it did rev out a bit more than our other bike my guess 2mph quicker on the top end if that
