I don’t ride my 401 constantly at those high speeds, it’s a city bike, not a motorway tourer. If that’s what you do with yours, then you have the wrong bike. There are FAR better high speed motorway machines out there.

I get about 24km/litre on my city commute. And I’m pretty happy with that, especially as I’ve shortened the gearing.

It’s not a mystery that there is no change in voltage of those 6 wires when different lamps are lit. The lamp functions are driven from the CAN module on that circuit board. It takes input from the other bike CAN modules such as the ignition, engine, instrument pack, etc… And then it switches the different lights on and off digitally via those…[Read more]

Looking at that circuit board, you have 6 inputs:

GND = Ground

Vbat = 12V power

CANL & CANH = CAN network bus

HL_act = possibly flashing lamp button on handlebar

HB = high beam switch on handlebar

It might be that if you remove that CAN module (the headlight module) you may get other CAB Bus issues from other bike modules expecting to either…[Read more]

I always use Gear4 Motorcycles parts finder on their website. Has all the parts fiche and numbers and prices for all the Husqvarna bikes. If you tell me if your bike is EU or US spec (different fiches) I could check your part number. Or you could check out their website yourself if you prefer.

The tachometers on these bikes are more of a suggestion than an accurate instrument. Mine shows about 2000rpm when idling (after warming up) too. I think it’s fine, I’m not worried about it. I suspect the actual idle rpm might be a little less, as the little LCD ‘squares’ flicker, suggesting the RPM isn’t high enough to fully display the 2000rpm…[Read more]

I have the Anti-Gravity 801 on my Svartpilen 401, it’s a great piece of kit.

I have also recently installed a Rekluse manual Torq-drive Clutch pack to a bike (although not a Husqvarna) and I’ve been very impressed with it. It’s improved the clutch operation greatly, I’d definitely recommend it.

That doesn’t make sense, the ‘black box’ is the pre-muffler, it’s not the cat. The cat is smaller and is situated roughly half way between the engine and the ‘black box’.

Even though my 401 starts up just fine, I’m still going to check these solenoid connections and make sure they are nice and tight. Thanks for the heads up.

I think we will see at least another iteration of the small and mid sized ‘Pilens with petrol engines. The 901 Norden is coming soon, and I’d be surprised if we don’t see smaller twin cylinder Vitpilen and Svartpilen bikes badged as 501 and 801. The new “e-pilen” concept is a little disappointing for me as it is very low powered with just 10hp.…[Read more]

It is still based on the same chemistry though. Just that the electrolyte is held in gel ‘pads’ rather than just liquid acid. Yes, gel is better than basic lead acid, but I have found that lithium is more of an improvement again, over both traditional lead acid and gel types. I have run a lithium battery in my Svartpilen 401 for 18 months now,…[Read more]

My dealer could only improve the function of the fuel gauge or range indicator very slightly. They did do a software update which at least stopped the range telling me I had 320 miles each time I filled the bike up. It is still erratic, but less so than before the update. Maybe it will improve for you too?

I gotta say, like Svartron, I’ve had good success when swapping the lead acid battery out for a Lithium battery. I would do it again on another bike without any worries.

I dunno if you’ve read any of the previous posts on fuel gauge issues? The fuel gauges on these bikes are generally not great, either poorly set up at the factory, or just plain variable. The most annoying thing I’ve noticed with my 401 is that as soon as the low fuel sensor is triggered, it automatically stops showing any actual level…[Read more]

Yep, my bike (401) does this too. So I always make sure to come to a complete stop, bike into neutral, then turn off the engine with the key. This avoids the ‘light staying on’ issue. It’s evidence of Husqvarna/KTM engineering team carrying out a very poor or non-existent FMEA (Failure Mode Effect Analysis) when designing and developing the bike.…[Read more]

Very interesting, thanks for the post 😎

Have you tried Grip Puppies?

Would it be possible to saw off those clip-on bar mounting points from the top triple tree? Then file it flush with the rest of the triple tree and touch up with some black wrinkle coat paint for a more factory look?

Here is my original thread

Fuel gauge thoughts…

My 401 has that sloshing fuel noise when the tank is full too. I’m pretty sure that’s normal.

The fuel level sensor on these bikes is very poor. Mine used to be like yours, only read 6 bars when full. I made a post on this forum about a tool I made to insert into the tank and bend the fuel level float lever/rod slightly downward. This allowed the…[Read more]

Are you messing with me? That photo you posted is of a Vitpilen 401, not a 701.

No wonder I could not find that plastic cover on the 701 fiche!

The plastic part is called the headlight mask electrical system box cover. It is shown on the “Mask, Fenders” page of the parts fiche. The screws which you are referring to secure this cover to the rear…[Read more]
