• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
    TE = 4st Enduro & TC = 4st Cross

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Slip-on silencer suggestions for TE511?

California .....:censored:

Santa needs to treat all dual sport motorcycle owners with new exhaust systems before the end of the year!
I think I will order a new Mega Bomb and a new system for the te310 now :thumbsup:
 
No Tinken, I have one of Ty's TXCs. Yes it is the Factory 4.1 RCT and Megabomb. It is hella loud without the "spark arrestor plug" in. Let me try and make a video.
 
Here you go. Best I can do in the garage with my phone. Didn't want to rap it out too much because it was cold so didn't really hear how loud it can get. Oh yeah, just now putting on my new to me SM wheels, so not fully buttoned up.

Video says it is private.
 
Works! Looks great and doesn't seem too loud. Did you have the spark arrestor/quiet plug in?
 
There is a special bushing that goes into the TC header to adapt it to a TE head, FMF makes it, but I do not have a part number available yet.


TC449 header to TE parts:
1 - 8000 H5995 Gasket
1 - 8000 H5992 Flange
1 - 8000 H5994 Sleeve
2 - 8000 H5393 Springs

Thirty dollars for a spring, really? Why did I buy a Husky again? Oh yea, I remember now...

TC449 header to TE parts: $158.78

1 - 8000 H5995 Graphite Gasket $24.15
1 - 8000 H5992 Flange $35.88
1 - 8000 H5994 Outer Sleeve $66.97
2 - 8000 H5393 Springs $29.28
 
I gotta say that overall I havent found Husky parts to be any worse than Honda for prices....and I have to buy very few of them.
 
cheaper than oem KTM parts, that's for sure. But that Outer Sleeve and flange are way over priced. Ty designed a prototype that was better and FMF manufactures the part. Hopefully I can use one of those.

Went to go pick up my new exhaust today, but it was stolen from the shop. Thankfully have one on order to pickup in a few days :)
 
Yep. I just priced them trying to figure out how to get a proper headpipe mounted on our new TXC310R we will be racing this year.
 
Finally got my adapter set for my TC header.
In the image below, #3 is misleading, it is a copper ring gasket that fits inside the head and #5 presses against it. I substituted Moose Racing stainless steel springs for husky springs since they were $13.95 for two vs. $50 for two. The end of the header actually fits inside of #5 and not around it and presses against the copper ring gasket.

And here is what Santa left for me under my Christmas tree:

Almost identical to Drd's system, except for the modified insert. This is the full GYTR race system used on the factory bikes @ Zip-Ty Racing. Stainless steel Megabomb header, mid pipe and titanium factory 4.1 blue anodized rct.

The insert can be created from a stock insert that is bored horizontally. Then a custom wire mesh can be welded on the interior of the quiet plug. This allows enough gas to pass in order to tune to peak hp and still keep close to a 96dB tone.

This is the stock unmodified 94dB quiet insert, but constricts a little too much.
Bellow is the insert from a Akrapovic TC exhaust and has been modified in a similar fashion, but this one does not have the screen over the tuned ports.

Another mod is to purchase just the GYTR spark arrestor and use double sized screen. I don't have an image of mine yet, I will remove it from the silencer and post an image later.

This pertains to riders in California.

California SB435 LAW changes concerning Loud Motorcycle Exhaust Pipes. It looks like the LAW comes into power on the 1st January 2013. However, from 1983 performance exhausts must have a DOT approved sticker ? For us folks in California that means a fmf has to have a sticker !!! - So if you buy a exhaust after the 1st, have them back date your receipt... haha. Damn Harley people...


SB 435, Pavley. Vehicles: pollution control devices.
(1) Existing federal regulations require a motorcycle manufactured
on and after January 1, 1983, and exhaust emission systems for those
motorcycles, to meet specified noise emissions standards and require
that a label be affixed onto the motorcycle or exhaust emission
system indicating that the motorcycle or exhaust emission system
meets the noise emissions standards.
This bill would make it a crime for a person to park, use, or
operate a motorcycle, registered in the state, that is manufactured
on and after January 1, 2013, or a motorcycle, registered in the
state, with aftermarket exhaust system equipment that is manufactured
on or after January 1, 2013, that does not have the above label, and
would make a violation of this provision punishable by a specified
fine, thereby imposing a state-mandated local program by creating a
new crime. The bill would require the person to whom a notice to
appear is issued, or against whom a complaint is filed, for the above
violation, to provide proof of correction. The bill would authorize
a court to dismiss the penalty imposed for a first violation if the
person produces proof of correction to the satisfaction of the court.
(2) The California Constitution requires the state to reimburse
local agencies and school districts for certain costs mandated by the
state. Statutory provisions establish procedures for making that
reimbursement.
This bill would provide that no reimbursement is required by this
act for a specified reason.
THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS:
Page 1
SECTION 1. Section 27202.1 is added to the Vehicle Code, to read:
27202.1. (a) Notwithstanding any other law, a person shall not
park, use, or operate a motorcycle, registered in the State of
California, that does not bear the required applicable federal
Environmental Protection Agency exhaust system label pursuant to
Subparts D (commencing with Section 205.150) and E (commencing with
Section 205.164) of Part 205 of Title 40 of the Code of Federal
Regulations. A violation of this section shall be considered a
mechanical violation and a peace officer shall not stop a motorcycle
solely on a suspicion of a violation of this section. A peace officer
shall cite a violation of this section as a secondary infraction.
(b) A violation of this section is punishable as follows:
(1) For a first conviction, by a fine of not less than fifty
dollars ($50), nor more than one hundred dollars ($100).
(2) For a second or subsequent conviction, by a fine of not less
than one hundred dollars ($100), nor more than two hundred fifty
dollars ($250).
(c) (1) The notice to appear issued or complaint filed for a
violation of this section shall require that the person to whom the
notice to appear is issued, or against whom the complaint is filed,
produce proof of correction pursuant to Section 40150.
(2) Upon producing proof of correction to the satisfaction of the
court, the court may dismiss the penalty imposed pursuant to
subdivision (b) for a first violation of this section.
(d) (1) This section is applicable to a person operating a
motorcycle that is manufactured on or after January 1, 2013, or a
motorcycle with aftermarket exhaust system equipment that is
manufactured on or after January 1, 2013.
(2) Penalties imposed pursuant to this section are in addition to
penalties imposed pursuant to any other applicable laws or
regulations.
(3) This section does not supersede, negate, or otherwise alter
any other applicable laws or regulations.
SEC. 2. No reimbursement is required by this act pursuant to
Section 6 of Article XIII B of the California Constitution because
the only costs that may be incurred by a local agency or school
district will be incurred because this act creates a new crime or
infraction, eliminates a crime or infraction, or changes the penalty
for a crime or infraction, within the meaning of Section 17556 of the
Government Code, or changes the definition of a crime within the
meaning of Section 6 of Article XIII B of the California
Constitution.
 
Finally got my adapter set for my TC header.

The constant struggle between noise and power!

I didn't see that one pictured above in the TC parts pdf, but it looks like one of the 'quiet' inserts I've ordered (but who knows with website stock images). I spent a bit of time trawling through Akra pdf's trying to find compatible inserts for my full Akra Ti EVO system to knock the noise down but not power. Hopefully both ones I've ordered turn up before I'm at the track early February where they have a calibrated db meter. With the pipe fully opened up it's too way loud (no idea on db), with the provided insert (P-SA004) it's way too restricted and down on power. Does let you hear some awesome induction noise though...

Pic of the size diff between opwn and restricted Here Ignore the crack in the CF, don't move bikes when you have an inner ear infection and no sense of balance!

I have no idea what the inserts look like so I've ordered blind, I'm assuming that they fit as the P-SA004 insert supplied with my pipe is also listed in the Akra PDF's for other bikes (eg. CRF250R) where the other inserts were listed as optional. I'll post up pictures and noise readings when I get to the track.

On order are both Akra items;
P-SA014 - 2 Metre Max insert and
V-TUV077/Ti - Noise Reduction Insert.

Ultimate aim is to get the noise *just* under the limit without sacrificing too much power.
