2010 FE 570 hard starting cold

I have had a new fuel pump @ 100 miles & the remap both under warranty. The problem now is its real hard to start cold. I beleive there is not enough cold start enrichment. Anybody able to shed some light on this. Lomg crank time, pops, then finally starrts. Cold start knob pulled out has no effect. Thanks

Re: 2010 FE 570 hard starting cold

How long is long? Mine usually needs to be cranked for good 3-4 seconds when dead cold. Sometimes it pops a little and starts after that. Warmed motor starts right away. Could the battery be reason for this or my aggressive map on the map switch?

My friend -10 570 starts pretty much right away even in dead cold condinition. But his bike is stock with just akra pipe.

Might want to check the idle adjustment. Had a friend who had been inadvertently turning the idle adjustment when he was pulling the "choke" out. That button is also you idle adjustment. If it gets far enough out of whack, the bike is really hard to start cold.

Pretty much standard for mine. Mine got better over time but what I do now is just punch the button to prime the pump then barely crack the throttle and try to start it. Usually works. Here at sea level in the heat of Florida the cold start button has no effect. I recently rode in Colorado at 8-12k and 40 degree temps and the cold start buttom actually worked in that scenario.

Re: 2010 FE 570 hard starting cold

Heres the drill to get it started cold...punch starter once to get pump primed. Then crank crank crank stop. Crank crank crank stop. Crank crank crank stop. Crank crank crank sputter. Crank crank crank sputter some more. Crank crank crank FIRE. That wasnt so bad until the other day it wouldnt reastart after sitting for half an hour. Finally started after almost an hour...man, I was sweating bullets. I was in the middle of Nowhere by myself w no possibility of pushing it out to the road & no access roads in. Spoke to dealer , hes talking to Husaberg about another pump.They really are trying to help.Went out w a freind yesterday & it was pretty much ok all day except for a couple of times it didnt refire right away w varying lengths of sitting in between. the battery is always fully charged and cranks fast. Although the battery bolts need to be tightened every few hours. Runs like a monster any other time. Thanks for any ideas.

Re: 2010 FE 570 hard starting cold

1Trak,

So, did you try Crazy Ted's suggestion about altering the idle speed? If you have the idle speed set too high it will be hard to start cold. Try setting the idle speed lower and let us know if that helps on cold start.

I'm also wondering at this point about the health of your injector. Typically when the injector starts to go bad it will drip some fuel after the bike has been running, causing it basically to be flooded after sitting for a bit when hot.

That's what my 09 started doing after about 100 hours. I replaced the injector at 130 hours, and now it starts hot if you barely touch the button.

Sounds like your dealer is doing you right, so here are a couple of suggestions.

Have the dealer check the fuel pressure. They have an in line plug in fuel pressure gauge, and this is part of the regular maintenance to check the health of the in line/in tank fuel filter, as well as the disposition of the fuel pressure regulator.

See if your dealer will throw in a new injector for you to see if this cures your problem.

I have a question...............What type of fuel, and octane rating are you running?

Re: 2010 FE 570 hard starting cold

Yes, I tried a lower idle speed all that did was cause stalling on big log hops. Now i know why fact. spec. for idle is 1700 - 1800 RPM. I am using Sunoco 93 w 10 % ethanol. I will try to get them to put in a new injecter ,I think they did clean it last time. It had the white crap in it. Will post what happens.

Husaberg has authorized another fuel pump for me. We will clean the injecter as well. Hopefully this will be the end of this. At least they are being a stand up company. Will post results.

Re: 2010 FE 570 hard starting cold

When I bought my 2011 570 I was told it might be harder to start when cold but was told to pull the "choke"...and it would start...only ridden twice in 2 weeks, both times it started no problem.
