  • 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 The previous version was outdated and no longer supported.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!

te450 questions

Hi bought myself a 09 te450 last week and the thing is a beast !
I do have a couple of Questions though if someone would be kind enough to answer for me.

Im pretty sure the guy who owned it before me has done the standard power up, cos the lambda sensor has been removed.

but the thing is LOUD ! too loud for me

so i found in my little box of goodies a insert for the exhaust (about 20cm with holes in the end which is held in by a clip) i think most around here call it a db killer.
and now i find at WOT the bike backfires and coughs a little and blows a little black smoke

so my questions are
is a little backfire smoke and cough normal at WOT ??
does this db killer come standard with the bike ???
will my bike run noticably better without it ???
and if i choose to keep it in will i need to get my efi map changed ??
 
There is OPEN, Spark Arrestor, DB Killer (really not a db killer more like a gutted arrestor), Euro DB Killer
DB killer is not standard in the US- the spark arrestor is.
If you were running it open and it was tuned/or running appropriately in that state and you then put in the Euro DB killer (LONG tube, 20cm> sounds about right) then YES that will affect fueling and your tuning ALOT.

If you are going to run the a different incert you usually have to make fueling changes for optimum performance- sounds like this made a significant differeance for you. I personally would seek someone to tune with Ibeat. I would not continue to run it back firing, running overly rich(black smoke) and coughing
 
I also just bought a TE450. But no box of goodies :( I don't mind the noise and I'm sure mine has had the power up because there's a lack of O2 sensor and the thing is a weapon! But there is a MASSIVE rattle coming from the can. Sounds like it's coming from the back of the can but not too sure. Any ideas? Could it be the spark arrestor? Is it bad to remove that thing?

As a side note, I'm new to dirt bikes. Been riding street bikes most of my life. Maybe this can rattle is normal??

While we're asking questions here... I'm going to check and see if I have the cat converter in my midpipe. If I remove it, will I have to have the bike remapped?
 
AusHusky- you probably have all the "goodies" on your bike- the rest is junk that you take off the bike and put in that same box and call it "a box o' junk" that weighs 30 lbs...

The rattle is normal for these exhausts (the spark arrestor or insert you have is held by a circlip) there is just enough clearence to allow a rattle0 many have tried to get rid of that rattle- but most in the end slowly ignore it... Best I have found is putting some High Temp RTV silicone on the contact points when reinstalling the insert/spark arrestor).
