449/511 airbox mods

[spud1968]

I was looking at g2 didnt see one for a 449

 

[Dan Rich]

they have one for all 4 stroke huskys - will let you know how it goes when it gets here (cmon cmon cmon cmon cmon)

 

[socalsealkiller]

so your saying order a 2012 airbox and put it on the 2011?

No. Just the bottom half. That along with the boot between the throttle body and airbox.

 

[socalsealkiller]

Have you got one? pics? did you notice any change?

This info was via Husky North America and the guys @ Southern California Husqvarna in Brea. Bought my bike there and they are helpful and knowledgable. Especially Jeff in sales and Alan in service.

Fella's , following this thread here..... I have a 2012 TE 511 will the tc449 exhaust bolt up ? I been eyeballing the mega bomb FMF systems for the tc ..... Also since I have some SM patrons on this one I have some really nice SM wheels for a crf450r fit 04 and up I am selling or will trade strait across for a pair that will fit my husky.... I'm here in Cali and can make a trip !.... Thanks !

Got my wheels for $995 with sprocket, discs and spacer with black rims and red hubs from SoCal Husky. Pimp daddy!

Seal killer - what happened with the airbox? worth doing?
G2 throttle is here, installing it tomorrow, will let you guys know how it is to ride re throttle response, accel etc . . . .

 

[Dan Rich]

OK - G2 quick turn throttle - increases response by a claimed 10%. Verdict: pretty fucking good.

First of all as a comparison base my bike is 511 SMR, with the akrapovic ti pipe, no other mods, soon to have a JD tuner (awaiting its arrival).

Find it much easier to get the power that I wanted to the wheel with it - Im not sure if its just preference but now that its installed for me to be at max throttle is simply the drop of the wrist with no need to drop the elbow at all - feels like im able to roll on the throttle just as accurately if not more so through the turns - at the start of the twist it doesnt seem like its too much either. Lots easier to get the full throttle position, for power on demand and pulling wheelies either clutch or power in 1st.

Installation was simple, bar end off, switched the throttle tube and a small adjustment to the cables in the throttle body - side note - the internal bolt on the throttle body isnt long enough to compensate for the slack on my bike (pretty sure it will apply to everyone else too) and I dont like a slack uptake, moved both screws to the outside and tightened and it works like a charm, tightened them up and have marked it with chinagraph pencil to test movement at all, rode about 200 kms today with the new throttle - zero movement, easy solution. Great product.
Any questions let me know.

Been busy but will post when I know!

How did it go with the 2012 airbox??

 

[reveille]

Wow this thread just fizzled out??? What is the final verdict with the stock TE511 airbox? Leave it alone? Install the TC449 version? Possible DYI mods? Inquiring noobs want to know. LOL
I have a G2 ergo dirt tamer on my 310 and it rocks! Wondering if it will fit a 511? probably is my guess...

 

[K5PL5]

Im pretty sure guys have been placing the TC449 lower box with intake horn on their TEs.

 

[ascribner]

Just remove it completely. That is what I did.

 

[Rearwheelin]

I hated that stupid airbox too ! And I have all the hardware you need in the box , never used to replace the whole stock box with a pod filter setup( minus the k&n ) will give it free with purchase of my like new CS sprockets . I have the oem 13,14,15t plus oem chain and stock rear sprocket. $50 shipped ! Pp lol

Barking up wrong tree there, modern day airboxes are way more advanced the XR650 or TE610's. In particular, the airbox design on the 449/511 is very optimized for performance. Of all the things they have modified for factory Dakar bikes, stock airboxes are just fine there and not a choke point. Muffler and header is your first priority, then a tuner if you want to fine tune.

Bunch of SM guys on supermotojunky say the Dyno shows very good results from airbox mods. Bikes have limited space for the airbox and is still a place to gain power from.

Never bothered with the intake horn (no one I know personally has), but the 2012 TC449 airbox lid is a good start, or just holesaw a few 40mm holes in your stock lid and epoxy some mesh over the cut outs.

 

[Tinken]

There are gains in the air box, but replacing with a K&N without retaining the air horn will put you backwards in the gains department. The older TC air horn is smaller than the newer SMR/TE horn. This is because the original throttle body was 42mm instead of 46mm which is huge. That whole down spout tube is tuned to the engine. I think a better option would be to do away with the front lid all together. Replace the foam filter with a K&N box filter and add a retaining mechanism.

When I see the data from the dyno, I will believe it. I will see if I can get mine over for a dyno day here sometime soon and we can talk about it once I have some data. I may snag the air horn and run back to back with the horn and with the silicon tube. Depends how much time I have on the dyno. You don't happen to have a spare one lying around do you? (I mutilated my original when trying to make the K&N work).
