    Cleaning carter/New issue: starter problems.

    Try paint thinner or spray gun cleaner on a cotton bud. Try it on the engine casing first somewhere you cannot see. If it does not melt the casing paint it should be safe to gently try on the white paint. If it does not melt the white paint you could paint over it with model (Airfix, Revell...

    My New Svart 401

    Standard suspension is very good for most situations, I agree. Being able to adjust the forks and shock is a great feature and one of the reasons I bought this bike. When I last rode a bike 15 years ago, WP suspension was a true upgrade, like £1500 minimum for a shock and forks. Obviously I...

    My New Svart 401

    Read your thread, 👍. Thank you for reading, as for mirrors I have bar ends in the down position. I tend not to drive in town - city as I live in a very rural part of the UK but need mirrors for overtaking and tend to not rely on them. My bar ends look great as they remove the bits sticking out...

    My New Svart 401

    New Nitron shock arrived today, a lot earlier than I expected too. the quality of the machining is superb, better than I thought it would be. I weighed the WP original at 3150g and this Nitron is 2035g, so a nice drop in weight aswell. I ordered for 90kg-95kg 'road' rider only weight as I will...

    Svartpilen 401 - Barcelona Catalunya RaceTrack

    What tyres are you running? I take it not the Rally STR! They look like Michelins?

    Svartpilen 401 - Barcelona Catalunya RaceTrack

    Love your videos, the sound adds such atmosphere. I am very envious of the weather you have though. Really makes me want to book a track day. 👍

    My New Svart 401

    Thank you, I preferred the silver to the black one. There is enough black on it already, if you can have too much black on a bike!!

    My New Svart 401

    Yes of course, the sag is not far off with my rear preload on max (10 ramps) though it could be less. The front is spot on but I may need to adjust my rebound and compression a little once the shock is in.

    My New Svart 401

    No a complete new shock from Nitron. I had looked into changing springs but there are no companies doing just a spring here in the uk. I found a company, Faulkners, that make springs. They make a 58.5mm internal spring in the length needed (180mm) for the WP rear shock. These come in various...

    My New Svart 401

    Suspension testing update…. I am running 180mm air gap of 5w oil in the forks using 15 clicks of rebound and 12 of compression. Front dives a little under hard braking but settles quickly back again, ride is firmer than stock springs but not harsh at all. I am using 10 (maximum) preload on the...

    2021 401 rear shock

    I have my rebound at 20 for the shock. It is overdamped for sure, I tried at 15 but the rear wheel felt like it was skipping and was going to lose grip mid corner. I kept backing the rebound off until it felt settled. Even on Max preload the damping on mine is next to nothing and still a bit...

    2021 401 rear shock

    My rear shock has 10 ramps for preload, mine was on 5 when I bought it new. I set it to 7 to begin with as for me 5 was too soft. I have it on 10 now as at 95kg it was still too soft. I assume your shock has 10 ramps also as the sticker under the seat says set to 10 for full payload? If the OP...

    2021 401 rear shock

    Sorry, I should have asked, is the spring white? Does the back end bounce when you push the seat down? When the bike is upright without you on it, can you lift the rear up a bit or a lot? As far as I can tell from many sources for svart-vitpilens and KTM duke 390’ I know of nobody running with...

    2021 401 rear shock

    Have a measure of the bikes static sag ( just bike, no rider) and rider sag ( bike with you, fully kitted out, helmet boots jacket etc) static should be around 5 to 10mm these bikes are light at the rear. Rider sag should be around 25% of travel so travel for your bike 142mm so 36mm roughly. If...

    Non-Running 2020 Vitplien

    Front headlight alone is £705 here in uk. You can probably get a very nice and most likely looked after second hand vitpilen 401 cheap now the new 2024 model has come out. Genuine parts for these bikes are very expensive and can take a long time to arrive. In my experience anyway. I can get a...

    Mods before run in!

    Yes I was surprised how much smoother the fuelX made the low end feel, genuinely the best mod I think. Yes I bought it in November last year but bike was stored over winter. You’ll be getting an 801 then?

    Mods before run in!

    So, passed 620 miles and no issues at all. In fact the quick-shifter is a lot smoother now and engine pulls hard from 6000 up. The last time I went out a week ago I had done 630 miles once back home. Today I reset the service reminder, I was expecting it to go to 620 mile but no, it went to 4661...

    Oil change options

    I would check first that Husqvarna in your country allow self servicing and the use of non Motorex oil to maintain Warranty. I dropped the factory (definitely not Motorex) oil out at 340 miles. I really wish I had done this earlier as the condition of the oil and the bits of liquid gasket in...

    Updated photos.. mods now complete, bar end mirrors, new exhaust, stickers removed and tail bag for tools as the space behind the battery is now used for FuelX lite and wiring. Modded airbox cover also fitted. Bike runs lovely now, I could hear the lumpyness smooth out in the first few seconds...
