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 The previous version was outdated and no longer supported.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

Need help! 449 started to run crappy today.

Regulator is after the pump inside the tank. Pressure will remain constant in the fuel hose as long as the pump has enough volts & fuel to 'over-deliver' to the regulator.

That is a good question, looking at the schematics, the 449 show's a pressure regulator, but I have been told that the ecu can vary voltage to the fuel pump to increase/decrease pressure as needed.

I don't think it is that clever.
It might be, but it isn't even using the map sensor that is fitted....
 
I posted that over a year ago. Since then I have made huge improvements into the fuel system for the 449. I have purchased new Viton o-rings for the pump and regulator and am putting them into a kit. The oem o-rings leak so much fuel that pressure is rarely constant.
 
Took the lower fuel tank and pump apart today. I think I have low pressure from fuel pump and possible a clocked injector. After taking it apart and cleaning as good as I could the bike was getting on the gas better but FAR from rideable.
I find I'm pretty carefully not getting dirt in my fuel but where is all this black shit coming from?
Is it possible to buy new filters for the fuel pump and how the heck do you take the filter section off the plastic bits?
Where have you fitted the external fuel filter?

Dude, that's nasty!

From the thread, looks like they were fitting the filter in the hose between the main & tanks.
On the CFR450R filter, the similar filter is a unitary throw-away.
Unclip it & bin it, gauze & plastic frame are one piece. About $85 aus.

If the Husky one isn't avail separately [not listed in my parts pdfs i have :( ], maybe one of the other Keihin bikes may fit (YZF, CRF,KX, KTM....)
 
Those bag filters are the best, you should replace that one with the same. We also have recently developed a new fuel filter for efi bikes that is 10 micron stainless steel and it is an absolute filter unlike our competition's paper one.

Bag filter? As the one sitting inside the fuel tank on the pump? Maybe i have to finally order the ss oil filter and fuel filter from you guys!
Ordered my self a water temp sensor. Didn't cost more then 50$ so not an economy breaker.
 
Yes, the one on the pump. I can toss in a few updated o-rings for your pump too, the oem ones are junk.
 
Do u know how much the filters are. I was having the same problem with mine and have it apart right now sounds like a good thing to change.

No idea on the quality (i imagine not great) but here's a fuel pump kit with filters.
Could keep the pump as a back-up & just use the filters if price was an issue.:)

Injector was the faulty part! Better see what i can do in regards to adding another fuel filter to 2nd fuel tank.
