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 The previous version was outdated and no longer supported.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

2011 TE449 Running well with factory EFI system - finally

Oh and I just tried resetting the air screw to 2.5 turns out...I had it at 3...so its back in its "Range"

Got plenty of fuel in the tank....

Did my fuel pump die?

You must have loosened some wires during the airbox removal?? They probably only came fully out from engine vibration??

I've done this myself. Drove me crazy till I found the wires to the coil were loose and vibrated out.

Hope you still end up "huskyluv"
 
yes it is most likely a wiring loom joiner has separated - happened to me and the clip retainer tag had actually snapped of - now has a cable tie to hold it from coming apart again

Removed it.

2011 TE511
5600 ish miles
Has always been a pretty good running bike and better with each upgrade.
JD tuner
Free flow muffler
ZipTy remapped to map 3
Jumper plug in.
Clean air filter.
Earth-x battery installed / TPS reset

Was a fairly EZ mod. I greased the Airbox to boot/tube connection for extra safety. TB was slightly dirty but not bad for the miles / riding.

Starts quicker (Bat), started first time 6 or so times where before it seemed to do a start die once or twice before settling to a idle when cold. Not sure if this has anything to do with the BF (butterfly). Seems snappier and more responsive. Have only ridden it around the block real quick to warm the oil to change it and make sure it ran OK. It does seem snappier. I will know a lot more after a good off road ride but seems positive at this point.

Mine was open like this, turned the key on stayed there.

Thanks for the photos Motosportz - we look forward to seeing a more detailed ride report when you get the chance.
 
umm so. It started after it charged for a bit and seems okay. Maybe the battery was low then it got flooded or something....


Side note now my quickshifter wont fit at all. AT ALLLLLLL. So that is making me huskygiveup after the issue with the back warp 9 wheel....then my breather kit didn't fit because of the angle I welded my pcv auto tune sensor. UGH!

I need beer.
 
You just need to ride the crap out of that awesome bike bro. If you need a quick fix, I'll let you take either of mine for a spin...

Very odd Huskylove. My own bike would not start at times (before mods) with the old lead/acid battery, it sounded normal cranking, but found out it had been very slow after I got the Lithium battery. I imagine it was too low for the ECU to let it start.

same happend to me. I removed the FBW flap and started. Bike died and i had a hard time to start again. I recharged my battery and did TPS calibration. Then everything was good.
And i am happy with it now.
 
Just a thought for you guys with the newer (not 2011) bikes, while you are doing efi work you would need to make sure the 'run switch' is off (same as ignition switch on older bikes).
Possible the system is getting 'confused' if the 2nd shaft moves while removing screws & the system is 'live'.

Sounds like 9880sts worked well with a tps reset.

I don't have a '12 or '13 bike to test so just a theory.
 
Tinken is not convinced.

I do doubt that mid to top range power will be increased through the FBW butterfly removal - how about someone do a before and after dyno comparison
 
Correct, I don't see how full power would be better at all.
If the original system opens up the top butterfly properly at full cry, then they should be the same.

It is the rideability at the other throttle settings that improved out of sight, including mid range.
Dunno about you guys, but I'm not a full-house racer, I can't hold it wide all the time where we ride.
I do like my bike to 'snap' to attention when I get on the gas though, it does this now.

Also, & I mean this with the greatest of respect, Tinken isn't riding my bike.
 
I was installing a new fuel pump, and heat wrapping some wiring, kept thinking about this so, I disconnected
The battery and removed the secondary flap. Should be able to give it a go on friday/saturday.
 
Thinking about it (a lot obviously) I reckon the idea was to reduce the effective size of the throttle body at lower rpm & have it open up at high revs for maximum flow, a kind of have your cake & eat it too arrangement.
Just it doesn't always work on every bike....I reckon there are a few 'Monday' bikes like mine =(
What are they, 46mm throttle body or something? It is a huge port for a 450.
So I get what they were trying to do, but you have an injector, not carb & jets, good tuning of the maps should be able to conquer any dramas in the bottom end.

I can still tractor around in 1st on the original gearing, slipping the clutch & launching up rock faces without any surprises, then crack it & roost off down an open track. I'm loving it.
