That sure would be nice, gathering up info on CDI's from 06-09 and seeing what kind of timing curve each one has.

I would think if you have an 08 or 09 then the 06 would be best but going from an 09 to an 08 would pretty much be the same thing.

Thanks for the info gunner I plan to buy an 06 box based on what you just posted.

The '06 advance curve is the most aggressive of the years listed in the original post. Although each is apparently different (given that they have different part numbers), based on their performance, I have the feeling that you'll find the '07-'09 to be somewhat similar. One of those 3 may still suit you better than another though. There are cam timing differences between the '06, '07, and '08-'09 models also.

I'm not aware of whether the '03 -'05 units will physically or electronically interchange with the later ones, but the '03 -'04 have a very aggressive map. In fact those years are typically criticized as too aggressive. The '05 was remapped in order to address this, but is generally thought to be too "soft" as a result.

... it is not possible for added weight to increase power.

It is if the engine in question is built with minimal rotating mass, and is being operated at the lower end of its rpm range:

Just got my 06 CDI delivered by UPS, it is the right part number (2s2-00). Can't wait to try it out. :banana::banana::lol::banana:

I have a 2007 and was wondering if the 06 would make it better like on the newer ones?

I have a feeling it will, but I won't know for sure until you try it. :banana:

Well, I just had the opportunity to try the 06 CDI on my 08 yz450f. My initial reaction was :jawdrop:, followed by :):applause::lol::cheers::thumbsup:. The first thing I noticed is how much easier it breaks the rear tire loose, even moderate applications of throttle caused the tire to spin significantly more than with the stock CDI. It's noticeable how much harder it pulls, it pulls harder than before at lower RPM's. I went to try out a section of hillclimbs with deep hard-pack whoops, it climbed beautifully and effortlessly. From there, I went to ride some black diamond single track trails, with sections going up, down, and parts full of loose rocks, along with some areas that call for lower speed. The surprise there was how much grunt it had right off from idle, trails like that used to required some clutch action to keep the engine from stalling, but now there was NO clutch slippage necessary, the bike just kept chugging along with minimal throttle application. My jaw pretty much dropped by how much the engine could be lugged in the slow areas. I'd rate the combination of the 08 yz with the 06 CDI a 10/10.:thumbsup: It's the best $40 I've spent in a long time.
