That is good news! I await further developments eagerly 🙂

Oops! Oh well, my clamp is over-torqued then :-/

It took the 20Nm easily though and there is a spacer between the two halves so that no matter how tight the bolt is done up, they can’t touch each other.

All I can say is that it worked and doesn’t leak.

Will there be a version for the Svartpilen 401? And can I keep my original grips and switchgear?

On page 237 of my SP401 manual it gives the torque for the exhaust clamps as 20Nm. I removed my muffler (to remove the dB killer) and then put it back on using the original gasket and torqued to 20Nm and experienced no leaks.

Strictly speaking, gaskets are not re-usable, but as long as they are not damaged and still fairly new, you can usually…[Read more]

Yep, something to do with how soundwaves work. A smaller pipe sitting partially inside a larger one breaks up the power of the waves, hence ‘dB killer’.

You can see similar ones on other aftermarket systems such as Yoshimura, Akra, et al…

So making sure that the small pipe doesn’t sit inside the larger one, but instead meets it at the ends…[Read more]

I detailed how I made the Evotech Performance swing arm spools (paddock stand bobbins) fit my SP401 in the thread “Making Evotech Parts Fit” in the Accessories section of the SP401 forum page.

In short I made an adaptor, and I guess that a similar adaptor would need to be supplied by any company who wanted to offer spools to fir the 401’s with…[Read more]

So, it’s a bit of a late reply, but I got my exhaust back together after modifying the end cap. I cut off 60mm of the dB killer so that it ends flush with the end of the perforated pipe. This should stop any glass wool packing from coming out of the exhaust but still make the sound louder.

As I mentioned before, the inside of the end cap had…[Read more]

You can’t set the shift light function until after the first 1000km (621 miles). I think it also says this in the manual. This was certainly true for my bike. It makes sense because during the break-in period, the shift light is set to a factory recommended rpm limit that you are meant to stay below.

Just been to the London motorcycle show today, and of course I went to visit the Husqvarna stand. There were 6 bikes on show: two of the more traditional off-road Huskys, both of the new 2020 701 ‘Pilens, but annoyingly still no 2020 401s. Instead they displayed the 2019 401s. And also no ‘Norden’ concept bike either. I was rather disappointed and…[Read more]

Pretty sweet!

As a further refinement I decided to alter the bobbin stand-off lengths. I noticed that the right hand bobbin was much closer to the swing arm than the left hand bobbin so I made the following adjustment:
The Evotech bobbins come with an aluminium spacer that fits inside each bobbin. These make the bobbins stand off from the swing arm. They are…[Read more]

So, fitting the Evotech rear paddock stand bobbins to a standard Svartpilen 401 that hasn’t has it’s rear number plate bracket removed? It is possible, but requires the machining of an additional location adaptor.

The Evotech rear paddock stand bobbins that are sold for the Duke 390 include cap-head fixing bolts that are M10 x 1.25mm fine pitch…[Read more]

Nice photo!

In the owners manual at the back it lists all the torque values for all the external fixings and fasteners, plus general torque settings for M4, 5,6, etc… on the bike. There are no diagrams (there are in other sections of the manual) though, but I’ve still found it very useful and helpful.

Not sure about the 701, but in the owner’s manual that comes with each 401, all the nut and bolt and fixing torques are listed in the back pages of the manual. Very useful. IIRC the torque for the 401 rear axle nut is 90Nm.

I posted about this in the thread about removing the dB killer from the stock end can.

The factory use the cheaper unsealed (standard) rivets in the stock exhaust systems. For a vehicle with a supposedly Euro-compliant emissions system, this is very bad practise. Reputable aftermarket exhaust manufacturers such as Akra and Yoshimura use the…[Read more]
