CDI compatibility ?

Will a CDI from an 03 or 04 plug into an 09 450?

The connector interface "looks" the same, and I've heard people say they've done it.  That's about as far as I can go with it.  I was never interested enough to try it, even though I had both bikes for a time.  The '06 map has much better power management at the low end and revs considerably better above 7000 or so than the '03 I had.

I have the 06 cdi and a Dr D pipe and there r times I want more grunt. What about other year cdi's? Edited by Gunner354

Gray, I'm interested in getting the 06 CDI for my 09 because it seems like a cheap, easy bolt on mod. I was wondering do I have to get an oem 06 CDI box, or can I get an after market one like BigGun? If I get an new aftermarket CDI, do I still get the one made for the 06, or get one for the 09 & it'll have the improved timing/etc?

I picked up an OEM box from an '06 on eBay for $75 for my 2009. Direct bolt on, very easy mod and it really helped the bike all around but especially down low. This one is a must do for an '09 in my opinion.

Most of the aftermarket stuff is programmable to some extent, or come with at least two maps to pick from.  Can't beat the reliability and simplicity of the stock '06, though.

The only two that might boost low end beyond what the '06 does would be the '03 or '04, both very similar maps.  The '05 was an attempt to "civilize" the '04 so mere mortals could ride it, but they went way overboard with it, and turned it sluggish.

 

Another thing to look into if those are the only two mods you've done to the '09 is to replace the exhaust cam with one from an '06, or replace both with '06 parts.  The exhaust cam swap will add more low-mid, while the '09 intake will hang onto some of the high end power.  If you don't run it really hard at high RPM too often, and you think you can give up 1 HP on top, the pair of cams is the way to go.  Or, beyond that yet, there's the pair of cams from the '03-'05 engines.  That gives up another 1-1.5 HP, though.

Cool thanks. I found an 06 on eBay for $68 at the cheapest I think. I'll just go with that one.

Well I just bought an 03 cdi and will report back when I try it. I realize the 03 was a monster, but I'm sure the cams were part of the combination. The 06 made a difference in my 09 but maybe the 03 will give it some more low end similar what the 06 did just more. The stock 09 cams should keep it from being a monster. Edited by Gunner354

I'm pretty excited to hear what the end result is here. Please report back on your findings.

Curious about the progress report on that. I too liked the change the '06 box did to my 2009, but if I could get even more bottom without sacrificing too much on top I would be interested. I'm not a rever anyway. Interesting thought about the more aggressive mapping of the 03 box with the mellow cams of the '09.

Yea I'd like to hear how that goes to. The kind of riding I do in the mountains doesn't ask for high reving. I like to carry my speed anyway, so if I can really add to the bottom & mid, I'll trade a little top for it. Let us know. Bet those are cheap, I haven't heard of a demand for that year, or is there like the 06?

I'm not sure if anyone has tried one on an 09. I found one at an unbelievably low price so I have to try it.

There's no jetting needed when changing out the CDI right? Man there's a few good deals on 03s right now, but I wanna wait to hear how yours goes. My 09 is smooth as butter & a little more grunt would be cool, but to much won't be good.

The 06 is definitely a big improvement along with the DrD pipe. Certain conditions I want a little more than what the 06 produces. Edited by Gunner354

I've got the fmf power bomb & 4.1. Does it really matter which pipe aslong as it isn't the stock can?

It matters, but not as much as getting rid of the stock can does.  To put it in perspective, switching to anything else is like a 20% improvement.  You can make another 5% improvement by selecting from among the different options.

 

The system you have is a good one.

Put a13.5 piston in it,it's got to be due for piston,etc.the bike's a 9.

Mine already has a new top end & timing chain.

Kinda off topic but compression is a relevant point as far as bottom end punch because the 03-05 came with 12.5:1 and the 06-09 came with 12.3:1
