Difference 06 to 09 header - pics

I've got an '06 header to run on my '09, thought it might be worth posting the pics of the two OEM headers. The 06 header is a little less than an inch and 5/8's, the 09 header is a little better than an inch and 3/4.

Below the pics of the headers is a pic of my '09, I've got everything greased and am starting to put it back together.

That's exactly what my bike looks like. :banana: Just waiting on some parts so I can put it back together. Can you measure the overall length of the 06 and 09 headers.:lol: You'll need a soft (flexible) tape measure . Thanks.

The headers were the same legnth, when I took the pics they were lined up and at the time I noticed the similarity in legnth. There might be a 3/16" difference at the most, if any difference at all.

What parts are you waiting on ?

I'm waiting on updated steering stem bearing with seal, 06 header, Radiator cages, NFPR needle, etc.. I like to completely go through all my new bikes and become familiar with them and also fix some things the guys mess up at the dealership:bonk:

I've got the bike almost all put back together, here's what I've done so far :

'06 stock header

'06 Pro Circuit T4 slip-on

'06 CDI

NFPR needle, 165 main jet

Boyesen accel. pump cover

Here's what I'm waiting on :

280mm front brake rotor

xw-ring chain & Ironman sprockets

Used plastic set & seat - I'll put the new stuff away.

Wondering about gearing though, I might ride it with the stock 13/49 then decide what I want to do. Which means waiting on ordering the Ironman stuff. I greased the steering stem bearings the other day, noticed that the seal has a double edge on it - what does the updated bearing/seal have that's different ?

Are you an MX guy or a woods rider? For woods you'll want a flywheel weight and lower gearing.

I'm an MX guy, might ride in the woods once every two or three years. I was wondering about putting a little bigger fly wheel weight on. Not something that would make a drastic difference, but I'm guessing there might be something (weight wise) that may give me a little better performance - even on an MX track. I've got to do a little more research on that though..

DIDO:thumbsup:

Yeah, I'm not really sure about the updated bearing, it was what I was told.

Things I've got so far:

06 Header

Modded stock muffler

06 Cam

50 tooth rear (cheap steel one)

RK520EXW Gold (Do I need a spacer)

Extra set of plastics

Moose radiator cages

Works Connection skid plate

First I'm going to ride it stock to get a base line and then I'll start adding and changing parts to find out what does what. It's a new bike so I need to dail it in, Lots of testing:ride:

The 06 header is a little less than an inch and 5/8's, the 09 header is a little better than an inch and 3/4.

So why put the smaller header on? Wouldnt the newer 09 thats larger flow better and therefore perform better?:banana:

No the bigger header flows too well once you get rid of the restricted shorty muffler. It takes away from the bottom end so a little bit smaller diameter will give you back the bottom end that is desired for rocketing out of corners.

I had an 06 and it was an awesome bike, had to sell it though and havent had a bike for a couple years. Did you have an 06 and Is the 09 much different or better?

sound simple, good to know why they actully change some stuff.:banana:

Just call me the rocketman.:banana: That's what I would like to happen, now all I need is my bike back together and some nice weather so I can start testing.
